Background: Perioperative cardiovascular complications remain a major concern in patients undergoing noncardiac surgery. Coronary computed tomography (CT)-based imaging, including coronary artery calcium (CAC) scoring, coronary CT angiography (CCTA), and CT-derived fractional flow reserve (CT-FFR), enables noninvasive assessment of coronary plaque burden, anatomic stenosis, and functional ischemia. However, the comparative prognostic value of these CT-based imaging markers for predicting perioperative major adverse cardiac events (MACE) has not been systematically evaluated. Methods: We performed a systematic review and meta-analysis of studies evaluating CT-based coronary imaging before noncardiac surgery. PubMed, Embase, and Cochrane CENTRAL were searched from inception through December 2025. Studies were included if they assessed CAC, CCTA, or CT-FFR and reported perioperative MACE. Risk of bias was independently assessed by two reviewers using the Quality In Prognosis Studies (QUIPS) tool. Pooled effect estimates were calculated using a random-effects model. The CT-FFR analysis was pre-specified as exploratory given the limited number of eligible studies. Results: A total of 13 studies including 10,100 patients undergoing noncardiac surgery were included in the systematic review, and 9 studies were eligible for quantitative meta-analysis. Obstructive coronary artery disease detected by CCTA was strongly associated with perioperative MACE (pooled odds ratio [OR] 7.18, 95% confidence interval [CI] 3.89–13.25). CAC burden was also significantly associated with perioperative cardiac risk (pooled OR 2.48, 95% CI 1.76–3.50). One study evaluating CT-FFR demonstrated a strong association between CT-FFR-defined ischemia and perioperative events (OR 10.77, 95% CI 4.64–25.02). These findings suggest that different CT-based imaging markers provide complementary prognostic information, with anatomic and functional assessment offering higher point estimates than plaque burden scoring. Conclusions: CT-based coronary imaging markers are significantly associated with perioperative MACE in patients undergoing noncardiac surgery. CAC burden and obstructive CAD detected on CCTA demonstrated consistent prognostic associations with perioperative cardiovascular events across multiple studies. CT-FFR showed a strong exploratory signal in a single eligible study, suggesting a potential additional role for functional ischemia assessment, although further validation in larger prospective cohorts is required. CT-based coronary imaging may therefore provide valuable complementary information for perioperative cardiovascular risk stratification. Full article

Postoperative cardiovascular complications remain a leading cause of morbidity and mortality after noncardiac surgery, yet current risk models do not incorporate psychosocial stress. With over 300 million noncardiac surgeries performed annually worldwide and a substantial burden of perioperative cardiovascular complications, preoperative chronic stress is increasingly recognized as a potentially modifiable risk factor. Chronic stress produces HPA axis dysregulation, glucocorticoid resistance, sympathetic activation, inflammation, endothelial dysfunction, and hypercoagulability. These pathways overlap with the mechanisms underlying perioperative myocardial injury, arrhythmogenesis, and venous thromboembolism. Prospective data demonstrated that preoperative psychological distress independently predicted 30-day cardiovascular complications and 1-year mortality after noncardiac surgery. Allostatic load studies in noncardiac surgery patients showed that high preoperative physiological burden was associated with up to twofold increases in postoperative mortality and elevated rates of myocardial infarction and venous thromboembolism. Epidemiological evidence further supports that anxiety and depression independently increase cardiovascular risk. Converging evidence suggests that preoperative psychological distress is a relevant perioperative cardiovascular risk factor. However, no randomized controlled trial has evaluated whether targeted preoperative stress reduction can decrease postoperative cardiovascular events, representing a critical gap warranting prospective investigation.

Perioperative neurocognitive disorders (PND) encompass a spectrum of cognitive impairments occurring across the surgical period and are associated with significant morbidity, delayed recovery, and reduced quality of life. Although established risk factors include advanced age, cardiovascular disease, and preexisting cognitive impairment, the contribution of mood disorders to PND susceptibility remains incompletely understood. This review systematically examines the neurobiological overlap between mood disorders, particularly major depressive disorder (MDD) and bipolar disorder, and PND, with emphasis on shared biomolecular mechanisms. We identify convergent pathophysiologic pathways including hypothalamic–pituitary–adrenal (HPA) axis dysregulation, chronic neuroinflammation, NF-κB-mediated cytokine signaling, microglial priming, tryptophan–kynurenine pathway dysregulation, and brain-derived neurotrophic factor (BDNF) suppression. These mechanisms collectively suggest that patients with preexisting mood disorders may enter surgery in a biologically sensitized neuroimmune state, lowering the threshold for exaggerated neuroinflammatory responses and postoperative cognitive dysfunction. Recognition of mood disorders as modifiable perioperative vulnerability states may inform preoperative risk stratification, guide anesthetic and analgesic management, and support the development of targeted interventions to reduce postoperative cognitive complications and improve surgical outcomes.

Background: Sodium–glucose co-transporter-2 (SGLT-2) inhibitors are widely prescribed for type 2 diabetes mellitus (T2DM) because of their cardiovascular and renoprotective benefits. However, their use is associated with euglycemic diabetic ketoacidosis (EDKA), a rare but potentially life-threatening complication characterized by severe ketoacidosis despite relatively normal blood glucose levels. Failure to discontinue SGLT-2 inhibitors before surgery, as recommended in current guidelines, together with perioperative fasting and surgical stress, increases the risk of EDKA. Diagnostic complexity is compounded when concurrent postoperative surgical complications provide an alternative explanation for persistent metabolic acidosis. Methods: A 71-year-old man with T2DM receiving uninterrupted empagliflozin underwent direct lateral interbody fusion under general anesthesia. On postoperative day 2, he developed severe high anion-gap metabolic acidosis (pH 7.204, HCO3 10.1 mEq/L) with near-normal blood glucose levels (178 mg/dL). Pneumoperitoneum identified on imaging was attributed to Hemovac drain-related peritoneal injury, and emergent laparoscopic exploration was performed under a working diagnosis of surgical sepsis. Although surgical source control was successfully achieved, severe metabolic acidosis persisted postoperatively (pH 7.275). Euglycemic diabetic ketoacidosis is an uncommon diabetic complication associated with several perioperative risk factors, including prolonged fasting and surgical stress. Subsequent serum ketone analysis demonstrated markedly elevated beta-hydroxybutyrate levels (4.8 mmol/L), confirming co-existing EDKA. Results: Following empagliflozin discontinuation, targeted treatment with concurrent insulin–dextrose infusion resulted in complete resolution of acid-base imbalance within five days. Conclusions: A concurrent surgical complication appeared to mask EDKA and contributed to a delay in its recognition. In patients receiving SGLT-2 inhibitors, metabolic acidosis that persists after an apparent surgical cause has been addressed should prompt measurement of serum ketones, irrespective of the blood glucose concentration. Structured perioperative protocols for SGLT-2 inhibitor management and postoperative ketone surveillance may help to prevent similar events. Full article

Background: Simultaneous pancreas–kidney transplantation (SPKT) restores both renal function and endogenous insulin secretion in selected patients with type 1 diabetes mellitus (T1DM) and end-stage renal disease (ESRD). Whether SPKT provides superior patient survival, kidney graft outcomes and cardiovascular benefit compared with kidney transplantation alone (KTA) remains debated, particularly when KTA is performed from a living donor. Methods: A systematic review was conducted according to PRISMA 2020 guidelines. PubMed/MEDLINE was searched using a predefined strategy including terms related to pancreas transplantation, kidney transplantation alone, T1DM, and ESRD/chronic kidney disease. Eligible studies included adult T1DM/ESRD populations comparing SPKT with KTA, including living-donor kidney transplantation (LDKT) and deceased-donor kidney transplantation (DDKT) and reporting clinically relevant outcomes. Full texts were reviewed and categorized as core comparative evidence, secondary/supportive evidence or excluded records. A quantitative synthesis was additionally performed for studies reporting directly comparable adjusted hazard ratios for patient mortality and kidney graft failure in the SPKT versus LDKT comparison. Results: Nineteen observational studies met the inclusion criteria and were included in the qualitative synthesis. SPKT consistently provided superior metabolic control and insulin independence when pancreas graft function was maintained. Compared with deceased-donor or mixed KTA cohorts, SPKT was frequently associated with more favorable long-term patient survival and cardiovascular outcomes in selected recipients. However, comparisons with LDKT yielded less consistent results, with several registry-based analyses reporting equivalent or superior kidney graft and survival outcomes after living-donor transplantation. Quantitative synthesis of the two studies providing directly comparable adjusted hazard ratios demonstrated a higher risk of patient mortality (HR 1.30, 95% CI 1.10–1.54) and kidney graft failure (HR 1.43, 95% CI 1.24–1.66) following SPKT compared with LDKT. Formal meta-analysis of SPKT versus DDKT was not feasible because of substantial heterogeneity in outcome definitions, statistical reporting methods and follow-up duration across studies. Conclusions: In adults with T1DM and ESRD, successful SPKT provides a durable metabolic advantage and may improve long-term outcomes compared with deceased-donor KTA in selected patients. Across analyses that included all transplanted recipients from the time of surgery (intent-to-treat), early perioperative risk is higher after SPKT but may be offset over time when pancreas graft function is maintained. Evidence does not support a universal survival superiority of SPKT over living-donor kidney transplantation. Our quantitative synthesis of intent-to-treat, transplant-date analyses indicates that LDKT is associated with lower risks of patient mortality and kidney graft failure compared with SPKT when a suitable living donor is available. Treatment decisions should be individualized, considering living-donor availability, anticipated waiting time and dialysis exposure, cardiovascular and surgical risk, and the likelihood of durable pancreas graft function, with greater weight given to contemporary cohorts.

Myocardial strain imaging, derived from speckle-tracking echocardiography (STE), has evolved from a research tool into a reproducible technique for detecting subclinical myocardial dysfunction. Recent advances in automated contouring and artificial intelligence have improved feasibility, reproducibility, and analysis speed, making multichamber strain assessment increasingly accessible in perioperative practice. Perioperative cardiovascular complications, including myocardial injury after non-cardiac surgery (MINS), postoperative atrial fibrillation (POAF), and heart failure, are associated with substantial postoperative morbidity and mortality. Conventional echocardiographic parameters, particularly left ventricular ejection fraction (LVEF), lack sensitivity for detecting early myocardial dysfunction. By quantifying myocardial deformation, strain imaging identifies subtle abnormalities in ventricular and atrial mechanics before conventional echocardiographic abnormalities become evident. Among available parameters, left ventricular global longitudinal strain (LV-GLS) and left atrial reservoir strain (LASr) provide the strongest evidence for perioperative risk stratification, with impaired values independently associated with MINS and POAF, respectively. Right ventricular strain (RV-GLS, RV-FWLS) and right atrial reservoir strain (RASr) remain promising but less standardized parameters supported mainly by observational data. Despite these advances, several barriers continue to limit widespread implementation, including vendor variability, the lack of standardized thresholds, and the absence of validated transesophageal echocardiography (TEE)-specific reference values. Importantly, current evidence supports myocardial strain primarily as a tool for risk stratification rather than for guiding therapy. No randomized trial has demonstrated that strain-guided perioperative management improves clinical outcomes, and its incremental value beyond established perioperative tools, including clinical risk scores, biomarkers, and conventional echocardiography, remains to be established. This review aims to provide a practical framework for the perioperative use of myocardial strain by summarizing the current evidence, clarifying its methodological limitations, simplifying its acquisition and interpretation for non-expert users, distinguishing established clinical applications from future research directions, and identifying the key evidence gaps that must be addressed before strain-guided strategies can be incorporated into routine perioperative care.

Coronary artery bypass grafting (CABG) remains one of the most effective treatments for advanced coronary artery disease; however, substantial variability persists in both perioperative and long-term outcomes despite advances in surgical technique, myocardial protection, and risk stratification. Oxidative stress is a central mediator of tissue injury during cardiac surgery, contributing to ischemia–reperfusion injury, endothelial dysfunction, systemic inflammation, and postoperative organ complications. At the same time, chronic exposure to ambient air pollution has emerged as an important environmental determinant of cardiovascular disease through mechanisms that converge on many of the same redox-sensitive pathways. We propose the concept of environmental oxidative priming, whereby long-term exposure to particulate matter, nitrogen oxides, ozone, and other pollutants establishes a persistent state of endothelial dysfunction, mitochondrial impairment, chronic inflammation, nitric oxide depletion, and reduced antioxidant reserve before surgery. Within this framework, CABG represents a second oxidative challenge superimposed on a pre-existing environmentally conditioned phenotype. We discuss the mechanistic overlap between air pollution-induced cardiovascular injury and cardiac surgical stress and examine how this interaction may contribute to postoperative complications, graft adaptation, major adverse cardiovascular events, and long-term survival. Recognition of air pollution as a modifier of biological resilience provides a novel framework for understanding outcome heterogeneity after CABG and may support future precision-based risk stratification and preventive strategies.

Background/Objectives: Hybrid operating rooms combine advanced intraoperative imaging, endovascular capabilities, and multidisciplinary resources within a single procedural environment. However, their use in otolaryngology remains insufficiently characterized. This study evaluated institutional patterns of hybrid operating room use, principal clinical indications, multidisciplinary involvement, and perioperative resource utilization in otolaryngology. Methods: We conducted a retrospective single-center study of eligible otolaryngologic procedures performed between 1 October 2018 and 31 December 2025. Patient characteristics, operative sites, hybrid operating room applications, multidisciplinary involvement, intraoperative blood loss, postoperative intensive care unit admission, and length of hospital stay were analyzed. Results: A total of 55 unique procedures were included. The median age was 46.0 years (interquartile range, 33.0–58.5 years; range, 5–76 years), and 33 patients (60.0%) were male. Computed tomography-based localization and navigation represented the predominant application, accounting for nearly three-quarters of procedures. The sinonasal cavity, nasopharynx, and skull base were the most frequently treated anatomical regions, comprising approximately 60% of operative sites. Angiography and endovascular intervention constituted the second most common application. Multidisciplinary collaboration, most frequently involving cardiovascular surgery and interventional radiology, was required in nearly one-quarter of procedures. Procedures relying primarily on intraoperative imaging were associated with a median estimated blood loss of 20 mL and a median hospital stay of 3 days. Cases requiring vascular, cardiopulmonary, or other advanced hybrid capabilities showed greater postoperative resource utilization, including more frequent intensive care admission and longer hospitalization. Conclusions: The hybrid operating room served as a versatile platform for image-guided, vascular, and multidisciplinary procedures in otolaryngology. Its capabilities were used during the management of anatomically complex and high-acuity cases, while differences in postoperative resource utilization appeared to reflect procedural complexity and baseline clinical risk.

Background: Endobronchial tumors represent a heterogeneous spectrum of benign and malignant histopathological types. Selecting the optimal surgical strategy remains a multidisciplinary challenge. This study evaluates how the integration of spirometry, DLCO, and CPET can objectively stratify cardiorespiratory risk and guide surgical decision-making regarding resection type, postoperative complications, and perioperative mortality. Methods: A single-center, retrospective study was conducted between 2020 and 2025, evaluating an initial screening cohort of 93 patients with endobronchial masses. Following multidisciplinary tumor board review based on functional and anatomical criteria, 36 patients were excluded from major resection due to extensive disease or prohibitive functional risk, while 57 underwent tailored surgical interventions, including sleeve resections, lobectomies, bilobectomies, and pneumonectomies. Preoperative evaluation included spirometry, DLCO, cardiological assessment, CT, and autofluorescence bronchoscopy (AFB). Results: Spearman correlation analysis demonstrated that advanced age and higher ASA scores significantly correlated with reduced preoperative DLCO (p < 0.0001). The overall postoperative morbidity rate was 36.84% (n = 21) and perioperative mortality was 5.26% (n = 3). Stratified analysis by surgical magnitude demonstrated a significant escalation in overall complication rates from parenchymal-sparing sleeve resections (17.6%, 95% CI: 3.8% to 43.4%) to standard lobectomies (40.7%, 95% CI: 22.4% to 61.2%), bilobectomies (50.0%, 95% CI: 15.7% to 84.3%), and radical pneumonectomies (60.0%, 95% CI: 14.7% to 94.7%; p = 0.042). Severe morbidity (Clavien–Dindo Grade III–IV) was significantly lower in the sleeve resection subgroup (5.8%) compared to pneumonectomies (40.0%, p = 0.015). Fatal outcomes occurred exclusively following major resections and were attributable to ARDS and acute cardiovascular events. Conclusions: A multi-parametric preoperative protocol provides an informative framework for risk stratification in endobronchial tumor surgery, helping to describe baseline reserves and explore post-resection trends. However, the anatomical and hemodynamic magnitude of radical pneumonectomy constitutes an independent risk modifier that cannot be fully captured by preoperative functional testing alone, highlighting the exploratory nature of these single-center retrospective observations rather than a definitive algorithmic validation.

Background and Objectives: Bilateral adrenalectomy (BADx) is a definitive treatment for diverse adrenal disorders, though data across etiologies remain limited. This multicenter study evaluated perioperative risks, long-term survival, and shifts in comorbidities in patients undergoing BADx for Cushing’s syndrome (CS) and non-CS indications. Materials and Methods: We retrospectively analyzed 103 adult patients (CS, n = 52; non-CS, n = 51) from 9 tertiary centers. Primary outcomes included early (≤30 days) and late mortality, complications (adrenal crisis, Nelson’s syndrome), and changes in comorbidity profiles. Results: The cohort (mean age 50.59 ± 13.82 years) had a median follow-up of 96 months. Early mortality occurred exclusively in CS patients (5.8%), while late mortality was comparable between groups. Overall 5-year survival rates were 83.3% for CS and 89.9% for non-CS (p = 0.360), with no significant differences across CS etiologies (p = 0.760). Adrenal crisis was significantly more frequent in CS (23% vs. 7%, p = 0.023). Nelson’s syndrome developed in 28% of Cushing’s disease patients. Postoperatively, both cohorts showed increased reliance on psychiatric and cardiovascular medications. Notably, osteoporosis rates were significantly higher than preoperative levels exclusively in the non-CS group (p = 0.006), highlighting the impact of long-term glucocorticoid replacement in this cohort. Two patients with congenital adrenal hyperplasia demonstrated remarkable long-term survival (8 and 30 years) across different surgical timings. Conclusions: BADx delivers rapid systemic remission and definitive control across a range of adrenal pathologies. However, the primary cause and the timing of surgery significantly impact the clinical course and the risk of complications. The resulting state of irreversible adrenal insufficiency requires comprehensive, lifelong surveillance and tailored hormone replacement. Full article

The association of atrial fibrillation (AF) and neck of femur fractures (NOF) are common in old people, creating a complex clinical scenario with significant implications for morbidity, mortality, and healthcare systems. This narrative review explores the bidirectional relationship between AF and NOF, focusing on shared risk factors, pathophysiological links, and challenges in clinical management, and also reviews the benefit of an orthogeriatric model. Advanced age, frailty, osteoporosis, polypharmacy, and cardiovascular comorbidities predispose patients to both conditions, while AF itself increases fall risk through haemodynamic instability, syncope, and adverse effects of rate- or rhythm-controlling medications. Importantly, the physiological stress of hip fracture and subsequent surgery can precipitate new-onset or worsening AF via inflammatory, neurohormonal, and metabolic mechanisms. The main challenge for ortho-geriatricians lies in anticoagulation management and preoperative and postoperative management. While anticoagulation reduces thromboembolic risk in AF, it increases perioperative bleeding risk in patients with NOF, often leading to delays in surgery that are independently associated with poorer outcomes. This review examines the current evidence regarding perioperative anticoagulation strategies, timing of surgery, and postoperative resumption of therapy. In addition, the review examines important outcome parameters such as mortality, stroke, bleeding, length of hospital stay, and functional recovery. This highlights the importance of not only improving multidisciplinary care involving orthopaedics, cardiology, geriatrics, and anaesthesia to optimise outcomes, but also enhancing risk stratification. Standardised perioperative pathways and integrated geriatric–cardiac assessment may help mitigate complications. Therefore, understanding how AF and NOF interact is key to delivering holistic, patient-centred care for an increasingly elderly population in orthogeriatric wards. Full article

Background: Mitral regurgitation (MR) is one of the most prevalent valvular heart diseases, with a rising global incidence. The 2025 European Society of Cardiology (ESC) guidelines introduced updated pathophysiological and morphological concepts for secondary MR, distinguishing ventricular and atrial mechanisms. Concurrent advances in cardiovascular imaging and therapeutic technologies have transformed the diagnostic and management landscape of MR. Methods: This review summarizes current evidence on the diagnosis and treatment of MR, with a focus on the updated ESC classification, multimodality cardiovascular imaging, minimally invasive surgical techniques, and contemporary transcatheter repair strategies. Recent literature was evaluated to highlight advances in anatomical assessment and individualized therapeutic approaches. Results: Multimodality imaging provides comprehensive evaluation of mitral valve anatomy, ventricular remodeling, and disease mechanisms, enabling accurate patient selection and procedural planning. Surgical management has evolved from conventional repair or replacement to minimally invasive approaches, including video-assisted right thoracotomy and robotic-assisted surgery, which have demonstrated favorable perioperative and clinical outcomes. In parallel, transcatheter interventions have expanded the therapeutic armamentarium for patients at high surgical risk or with complex anatomy. These include direct and indirect annuloplasty, transcatheter edge-to-edge repair, and emerging catheter-based repair technologies targeting specific structural abnormalities of the mitral valve apparatus. Conclusions: Contemporary management of MR requires an integrated understanding of disease pathophysiology, advanced imaging, and patient-specific anatomical characteristics. The combination of minimally invasive surgical techniques and rapidly evolving transcatheter interventions has broadened treatment options and supports a tailored, multidisciplinary approach to improve clinical outcomes and expand access to effective therapy for patients with severe MR.

Cardiac surgery remains a high-risk, resource-intensive domain in which perioperative complications significantly influence clinical outcomes, institutional performance, and healthcare expenditure. Despite advances in technique and protocol standardization, contemporary perioperative management largely relies on static risk stratification and reactive quality assessment. This narrative review synthesizes the current evidence on artificial intelligence (AI) and machine learning for perioperative risk prediction in cardiac surgery, spanning acute kidney injury, mortality, prolonged mechanical ventilation, postoperative atrial fibrillation, and intensive care unit deterioration, and critically appraises the methodological limitations, validation gaps, and fairness concerns that constrain clinical translation. Across these applications, predictive models have demonstrated incremental discrimination over conventional risk scores, yet remain predominantly endpoint-specific, single-institution, and disconnected from prospective clinical implementation. Building on this evidence, we propose Preventive Cardiovascular Intelligence (PCInt) as one possible organizing framework that integrates predictive analytics, dynamic risk trajectory modeling, and structured quality improvement methodologies, and we outline how such a framework might be operationalized across the surgical lifecycle. PCInt is presented as a conceptual proposal requiring prospective validation rather than as a validated system. We conclude by discussing implementation barriers, regulatory and ethical considerations, and priorities for future research toward anticipatory, value-based perioperative cardiovascular care.

Perioperative myocardial ischemia and myocardial injury after noncardiac surgery (MINS) remain prevalent contributors to postoperative morbidity and mortality. Recent advances, including high-sensitivity biomarkers and updated 2024 American Heart Association/American College of Cardiology (AHA/ACC) guidelines, have modified the clinical approach to preoperative ischemic evaluation. This review intends to synthesize contemporary evidence and provide a framework for perioperative ischemic workup. A narrative review of the current literature and major society guidelines was conducted, focusing on perioperative risk stratification, functional capacity assessment, biomarker utilization, noninvasive and invasive diagnostic modalities, and perioperative medical optimization strategies. Contemporary perioperative evaluation favors a stepwise, risk-based approach that uses clinical risk indices, functional capacity, and selective diagnostic testing. Biomarkers such as natriuretic peptides and cardiac troponins enhance risk prediction and enable the detection of MINS, which is strongly associated with increased mortality. Evidence does not support routine preoperative stress testing or prophylactic coronary revascularization in stable patients. Guideline-directed medical therapy, including sustained statin use and attentive management of antiplatelet and beta-blocker therapy, remains central to risk mitigation. Modern perioperative ischemic workup prioritizes individualized, evidence-based evaluation over routine testing. Integration of biomarkers, structured risk assessment, and multidisciplinary management may improve outcomes, though additional research is needed to define optimal strategies for detecting and treating MINS.

Introduction: Coronary artery bypass grafting (CABG) in patients with chronic kidney disease/chronic renal failure (CKD/CRF) poses additional surgical risk, both perioperatively and beyond, compared to their non-renal failure counterparts. Patients with end-stage renal disease (ESRD) are at particularly high risk for complications with prognoses limited by cardiovascular (e.g., myocardial infarction, heart failure, stroke) and non-cardiovascular (e.g., infection) conditions associated with the disease itself and the treatment of it (i.e., dialysis). For decades, cardiac surgeons have continued to offer CABG to patients with ESRD on dialysis with variable success. The purpose of this report is to describe a relatively contemporary analysis of CABG surgery in ESRD patients utilizing a pump-assisted beating-heart technique with the analysis of and comparison to outcomes reported by other investigators as well as predictions generated by the Society of Thoracic Surgery outcome tool. We report both short- and intermediate-term outcomes. Methods: From 1 January 2019 through 31 May 2025, the data from all consecutive patients undergoing BH-CABG at a single institution by a single surgeon were collected. Demographic information as well as a preoperative risk assessment was performed using the Society of Thoracic Surgeon (STS) Risk Assessment tool. The BH-CABG was performed via median sternotomy with maintenance of normothermia and ventilation throughout the case. Postoperative outcomes were recorded including mortality, major morbidity, and length of stay (LOS). Hospital/operative results were compared to the STS risk calculations. On-going intermediate-term follow-up beyond the index hospitalization was completed using direct or indirect methods (i.e., clinic, telephone, email). Results: There were 439 BH-CABG patients during the study period. Fifty-nine patients (13.4%) had ESRD on HD. There were 39 men and 20 women with a mean age of 61 years (41–76 years). Fifty-one (86%) underwent pump-assisted BH-CABG (PADCAB) and eight patients underwent complete off-pump BH-CABG (OPCAB). The mean ejection fraction (EF) was 48% (15–70%). The mean number of grafts was 2.3 (1 to 4) and the mean cardiopulmonary bypass (CPB) time for the PADCAB cases was 80 min (34 to 118 min). Patient presentation consisted of the following: one with cardiogenic shock, one with cardiac arrest, two with STEMI, 18 with NSTEMIs, 10 with CHF, five with NSTEMI/CHF, six with unstable angina (USA), and 16 with a positive stress test in preparation for renal transplant consideration. There was one operative mortality (1.7%), one stroke (1.7%), no reoperation for bleeding, no deep sternal wound infection, one prolonged ventilation (1.7%), and one prolonged length of stay (1.7%); overall mortality/morbidity was 5.1%. Comparatively, the STS-predicted mortality was 5.7%, stroke 2.2%, reoperation for bleeding 3.5%, deep sternal wound infection 0.6%, prolonged ventilation 17.8%, prolonged LOS 14.8%, and combined mortality/morbidity 26.8%. Thirty-six of the 59 patients remained alive (61%) in the follow-up period. Twenty-three patients expired (39%) in the follow-up: 11 of cardiac issues, eight of sepsis, two of stroke, one of gastrointestinal issues, and one of cancer. The average duration of survival for expired patients was 2.28 years (13 days to 5 years and 4 months). Nine patients (15%) underwent renal transplantation and six of them remained alive (67%). Conclusions: CABG surgery in patients with ESRD is complicated with historically high mortality and morbidity. The results of this study demonstrate significant improvement in the reduction in hospital mortality and morbidity. However, intermediate-term outcomes remain poor with a preponderance of cardiovascular and infectious deaths. A trend toward improved intermediate-term outcomes appears in patients in whom CABG surgery was performed for purposes of renal transplantation. Full article
