Background: Despite the increasing adoption of minimally invasive direct coronary artery bypass (MIDCAB), data on its long-term outcomes—particularly regarding sex-based differences—remain limited. This study presents a robust 20-year analysis comparing males and females, assessing perioperative outcomes, long-term survival, and independent predictors of mortality to inform sex-sensitive clinical decision-making. Methods: A retrospective cohort analysis of 676 patients (138 females, 538 males) undergoing MIDCAB was performed. Propensity score matching (PSM) generated balanced female and male cohorts (n = 129 each). Preoperative demographics, short-term outcomes, and long-term survival were assessed using Kaplan–Meier analysis and Cox regression modelling. Results: In unmatched cohorts, females exhibited significantly lower NYHA class distribution (p = 0.011) and higher atrial fibrillation prevalence (p = 0.038), with otherwise comparable comorbidities. Propensity score matching achieved cohort balance, and short-term outcomes—including 30-day mortality, stroke/TIA, and reoperation—were similar across sexes. Kaplan–Meier analysis of matched cohorts revealed no significant survival difference (log-rank p = 0.3370), though females demonstrated greater 20-year survival than males (77.6% versus 55.8%). In females, age 70–79 (HR 2.66; 95% CI: 1.02–6.95; p = 0.046) and cerebrovascular disease (HR 5.33; 95% CI: 1.49–19.03; p = 0.010) were independently associated with mortality. In males, significant predictors included diabetes (HR 1.86; 95% CI: 1.02–3.38; p = 0.042), chronic kidney disease (HR 4.92; 95% CI: 1.21–20.02; p = 0.026), pulmonary disease (HR 2.35; 95% CI: 1.20–4.60; p = 0.013), cerebrovascular disease (HR 4.77; 95% CI: 1.97–11.56; p < 0.001), and reduced left ventricular ejection fraction (HR 0.17; 95% CI: 0.06–0.43; p < 0.001). Conclusions: This 20-year study, the longest to date, demonstrates that MIDCAB achieves durable and equivalent long-term survival in males and females. It highlights sex-specific predictors of mortality, emphasizing the necessity for personalized preoperative risk assessment and postoperative management. Full article

Background: Minimally invasive off-pump coronary artery bypass grafting (MICS-OPCAB) offers potential advantages over conventional sternotomy, including reduced trauma and faster recovery. This study evaluates the safety and feasibility of MICS-OPCAB at our centre. Methods: We retrospectively analysed 50 consecutive MICS-OPCAB procedures performed via left anterior thoracotomy at our institution between January 2023 and June 2025. Data collected included patient demographics, operative details, and postoperative outcomes. Endpoints were 30-day mortality, conversion to sternotomy, and postoperative complications. Results: The cohort included 41 males (82%) with a mean age of 63.1 ± 8.7 years (range 40–80) and mean BMI 27.8 ± 4.3 kg/m2. Comorbidities included diabetes mellitus in 26%, COPD in 12%, and chronic kidney disease in 8%. Canadian Cardiovascular Society angina classes III–IV were present in 46%. The majority of patients (64%) had single-vessel CAD while 34% had two-vessel and 2% had three-vessel involvement. The mean Logistic EuroSCORE I was 2.19 ± 1.53. Left internal mammary artery (LIMA) grafting was performed in 96% of cases. Additional conduits included left radial artery in 32% and saphenous vein in 8%, with T-grafts in 26% and sequential grafting in 4%. The average number of grafts per patient was 1.35 ± 0.53 (range 1–3). The procedure was performed off-pump in 96% of cases, with two patients (4%) requiring CPB support during conversion from mini-thoracotomy. The overall conversion rate to sternotomy was 16% (eight patients), predominantly due to difficult or injurious IMA harvest or anatomical limitations. The mean operative time was 197.8 ± 76.8 min and decreased significantly after the first 25 cases (220 min vs. 175 min). Atrial fibrillation occurred in 18%, pleural effusion in 28% (10% requiring drainage), and chest infection in 8%. Wound complications arose in 4%. There was no 30-day mortality. ICU stay averaged 2 ± 2.2 days (range 1–14), and total hospital stay was 5.7 ± 2.7 days where institutional coronary bypass stay is normally 7.9 +/− 7.0 days. Conclusion: These results demonstrate that MICS-OPCAB is a safe and feasible approach for selected patients requiring multivessel coronary artery bypass grafting. There are some technical challenges during the learning curve for which conversion to open surgery can confer good outcomes. Traversing the early learning curve can confer additional benefits to later patients. Full article

Objective: Cardiopulmonary bypass (CPB) via the right axillary artery (RAA) has become an alternative perfusion strategy, especially in complex aortic procedures. This study delineates our technique and outcome with direct axillary cannulation utilizing the Seldinger technique, which we adopted as the standard perfusion strategy in the sternum-sparing minimally invasive total coronary revascularization via left anterior thoracotomy (TCRAT) using CPB. Methods: From November 2019 to December 2023, a total of 413 consecutive patients underwent nonemergent isolated coronary artery bypass grafting (CABG) via left anterior minithoracotomy on CPB with peripheral cannulation via the RAA and cardioplegic cardiac arrest, using this technique as a default strategy in the daily routine. All patients had multivessel coronary artery disease. The primary outcome was intraoperative cannulation-related complications (bleeding, revision, ischemia, wound healing complications). The secondary outcome was cannulation-related events during follow-up (blood pressure differences, incidence of brachial plexus injury, clinical signs of circulatory problems of arm and hand, re-interventions). Mean midterm follow-up was 18.7 ± 12.3 [1.1–51.2] months. During follow-up, 16 patients died. Overall, a total of 397 patients (344 male; 67.6 ± 9.7 [32–88]) were included for follow-up (100%). Results: The RAA was successfully cannulated in 100% of patients. A cannula size of 16 Fr was used in 34.6%, 18 Fr in 63.9% and 20 Fr in 1.5% of all patients. There was no intraoperative bleeding complication. In two patients, intraoperative revision of the RAA was required, necessitating a venous patch repair. At follow-up, there were no differences between the systolic and diastolic blood pressure or the pressure gradients between the right and left arm. Transient numbness of the right hand was observed in two patients. Permanent numbness was not observed. No patient needed further intervention or surgical revision of the RAA. Conclusions: The right axillary cannulation is feasible and safe in terms of vascular injury and brachial plexus injury with excellent in-hospital and follow-up outcome. Full article

Total Coronary Revascularization via left Anterior Thoracotomy (TCRAT) represents a modern evolution of sternum-sparing, on-pump multivessel coronary artery bypass grafting. In this review, we will summarize the historical development, detail the surgical principles, and provide a comprehensive overview of the clinical outcomes of TCRAT. The technique combines cardiopulmonary bypass using peripheral arterial as well as venous cannulation and cardioplegic cardiac arrest using transthoracic aortic cross-clamping with surgical access through a left anterior minithoracotomy. By applying special slinging and rotational maneuvers, both a stable exposition of all coronary territories—in particular those of the right and the circumflex coronary artery—and a quiet, bloodless operating field enable complete anatomical revascularization and complex coronary surgery procedures, including all variations in multiarterial grafting in unselected patients. Data from all published clinical series were integrated, and a weighted analysis of a total of 2282 patients was performed. TCRAT proved to be very effective with regard to complete anatomical revascularization and modern grafting strategies, and it showed excellent perioperative safety in an all-comers population. Both the 30-day mortality and perioperative stroke incidence were distinctly below 1.0%. Data from mid-term follow-up, although rare so far, are promising and compare well to those of the important RCTs. The TCRAT approach eliminates sternal complications completely and accelerates recovery. As an on-pump arrested-heart surgery, TCRAT inherently permits the combination of minimally invasive multivessel CABG with a variety of other cardiac operations, mainly the combination with valve procedures. The integration of robotic and endoscopic assistance represents the next evolutionary step. With its reproducibility and broad applicability, TCRAT holds strong potential to become a standard routine technique in the field of minimally invasive cardiac surgery. Full article

Minimally invasive coronary artery bypass grafting (MI-CABG) has emerged as a transformative approach to coronary revascularization, offering reduced morbidity, faster recovery and improved cosmesis compared to conventional coronary artery bypass grafting (CABG). Performed without full sternotomy and commonly without cardiopulmonary bypass (CPB), MI-CABG encompasses a variety of techniques. These procedures present unique challenges for the anesthesiologist, necessitating a tailored perioperative strategy. This review explores the anesthetic management of MI-CABG, focusing on preoperative assessment, intraoperative techniques, and postoperative care. Preoperative evaluation emphasizes cardiac, respiratory, and vascular considerations, including suitability for one-lung ventilation (OLV) and the impact of comorbidities. Intraoperatively, anesthesiologists must manage hemodynamic instability, ensure effective OLV, and maintain normothermia. Postoperative strategies prioritize multimodal analgesia, early extubation, and rapid mobilization to leverage the benefits of a minimally invasive approach. By integrating surgical and anesthetic perspectives, this review underscores the anesthesiologist’s pivotal role in navigating the physiological demands of MI-CABG. As techniques evolve and experience grows, a comprehensive understanding of these principles will enhance the safety and efficacy of MI-CABG, making it a viable option for an expanding patient population.

Background: The non-robotic endoscopic harvest of the internal mammary artery (IMA) facilitates minimally invasive bypass grafting while minimizing chest wall trauma. The technique was pioneered in the early 1990s and has recently regained popularity due to its accessibility and reproducibility. This review aims to provide an overview of endoscopic IMA harvest from its inception to the present. Methods: In August 2024, a literature search was performed using the electronic databases of the Cochrane Controlled Trials Register (CCTR) and PubMed. To obtain optimal search results, the keywords “thoracoscopic”, “endoscopic”, “minimally invasive”, “video-assisted”, “video-assisted thoracoscopic surgery VATS”, and “internal mammary artery” or “internal thoracic artery” were used, excluding the term “robotic”. References from the extracted articles were also reviewed to identify additional studies on endoscopic IMA harvest. Results: A total of 17 articles were included in the final analysis. Left internal mammary artery (LIMA) harvest times of between 17 and 164 min were reported, with an injury to LIMA rates between 0.7 and 2.2%. Conclusions: After a 15-year period without scientific publications, interest in the endoscopic-assisted approach has rekindled in recent years due to the reduction in chest trauma compared to direct vision harvest and the widespread availability of conventional endoscopic tools. This renewed focus underscores the potential to make minimally invasive coronary surgery available in all centers. Full article
