Background: Totally endoscopic mitral valve surgery has gained increasing interest as an evolution of minimally invasive cardiac surgery. However, concerns remain regarding the implementation of endoscopic techniques and their potential impact on procedural safety and operative efficiency. The present study aimed to evaluate the early experience of transitioning from direct-view minimally invasive mitral surgery to a totally endoscopic approach in an experienced minimally invasive center. Methods: A retrospective analysis of consecutive patients undergoing minimally invasive mitral valve surgery was performed. The study included 209 patients, comprising 36 totally endoscopic and 173 direct-view minimally invasive procedures. Propensity score matching was performed using age, left ventricular ejection fraction, and New York Heart Association functional class, resulting in 36 matched pairs. Continuous variables were compared using Student’s t-test and categorical variables using Fisher’s exact test. Results: After propensity score matching, baseline characteristics were well balanced between groups. The endoscopic cohort demonstrated significantly shorter cardiopulmonary bypass time compared with the direct-view group (120.4 ± 44.3 vs. 153.1 ± 40.1 min; p = 0.001). Aortic cross-clamp time was also significantly shorter in the endoscopic cohort (77.1 ± 23.9 vs. 97.8 ± 32.0 min; p = 0.002). Postoperative outcomes remained comparable between groups. The incidence of de novo atrial fibrillation was similar (11.1% vs. 13.9%; p = 1.0), as were blood transfusion requirements (47.2% vs. 50.0%; p = 1.0). Major postoperative complications occurred infrequently in both cohorts. Procedural success was achieved in 94.4% of direct-view procedures and 100% of endoscopic procedures (p = 0.493). Conclusions: Transition from direct-view minimally invasive mitral surgery to a totally endoscopic approach was associated with significantly shorter cardiopulmonary bypass and aortic cross-clamp times while maintaining comparable early postoperative outcomes. These findings suggest that implementation of totally endoscopic mitral surgery can be achieved safely in experienced minimally invasive centers and may be associated with shorter operative times while maintaining comparable early postoperative outcomes. Further multicenter studies are warranted to better define the impact of endoscopic techniques on operative performance and clinical outcomes. Full article

Background: Augmented reality (AR) and mixed reality (MR) promise to enhance anatomical understanding, spatial orientation, and workflow in cardiac surgery. Their clinical adoption remains limited and the translational path is incompletely defined. Methods: A PubMed search was conducted by two independent reviewers from database inception through July 2025 and identified peer-reviewed, English-language articles describing peri- or intra-operative AR/MR applications in cardiac surgery. Relevant clinical, preclinical, technical, and review articles were selected for inclusion based on scope and content. Given the narrative approach and heterogeneity across studies, findings were synthesized qualitatively into application domains. Results: Fourteen studies were included. Five domains emerged: (1) preoperative planning and patient-specific modelling—MR enhanced spatial orientation and planning for minimally invasive and valve procedures; (2) intraoperative navigation and visualization—AR improved targeting and interpretation with preclinical overlay errors ≈ 5 mm; (3) physiological/functional guidance—thermographic AR detected ischemia in vivo with strong correlation to invasive thermometry; (4) robotic integration and workflow optimization—AR-guided port placement and stepwise robotic adoption supported the feasibility of totally endoscopic CABG; (5) AR-based early rehabilitation. Conclusions: Early clinical and preclinical evidence supports AR/MR feasibility and utility for visualization and orientation in cardiac surgery. Priorities include deformable, motion-compensated registration, ergonomic integration with robotic platforms, and multicentre trials powered for operative efficiency and patient outcomes.

Minimally Invasive Cardiac Surgery (MICS) was developed in the late 1990s and has taken giant strides over the last 30 years. Nowadays, it is an important part of the cardiac surgery practice, accounting for one-third of total heart surgeries globally, with remarkable results. It is mostly performed for Mitral Valve repair but also for Aortic Valve Replacement and coronary artery bypass. However, the chronological evolution that led MICS to its current status has never been properly described. The best format to share a historical journey is the state-of-the-art (SotA) review. To the best of our knowledge, there are no orthodox SotA reviews on MICS. The aim of our study is to describe the current key MICS techniques, their historical development, and to discuss their role in the future of our specialty. 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

Background: The minimally invasive approach is increasingly recognized as the standard for surgical management of mitral valve disease. Advances in endoscopic visualization and surgical instrumentation have enhanced precision while minimizing trauma, improving both functional and esthetic outcomes. This study presents a single-center experience with total endoscopic mitral valve repair (MVR) performed using two- or three-dimensional video-assisted technology. Methods: Between October 2022 and September 2025, 239 patients underwent total endoscopic MVR at our institution. Demographic, operative, and postoperative data were collected and analyzed. Results: Median age was 63 years, with 64.4% male. Median logistic EuroSCORE and EuroSCORE II were 2.53 and 0.83, respectively. Most patients were NYHA class II (54.4%), and 47.7% had pulmonary hypertension. Mitral annuloplasty was performed in 99.2% of cases; 78.6% received Gore-Tex chordae, 6.3% underwent posterior leaflet resection, and 11.7% edge-to-edge repair. Conversion to sternotomy occurred in 0.4%. In-hospital mortality was 1.3%; stroke occurred in 0.4%. Postoperative atrial fibrillation developed in 26.8%, while major complications such as sepsis (2.1%) and renal failure requiring dialysis (1.3%) were infrequent. Median ventilation time was 5 h, ICU stay was 2 days, and hospital stay was 7 days. Pre-discharge echocardiography showed ≤mild regurgitation in 99.2%. Conclusions: Total endoscopic MVR using two- or three-dimensional video assistance is safe, feasible, and yields excellent clinical, functional, and cosmetic results, with low morbidity and rapid recovery.

Background: Totally endoscopic techniques have become increasingly popular in cardiac surgery, with minimally invasive mitral valve repair emerging as an effective alternative to median sternotomy. This approach could be particularly advantageous for patients with Noonan syndrome, who often present with structural thoracic anomalies and other comorbidities like bleeding disorders. Endoscopic mitral valve surgery is rapidly establishing itself as the new standard of care for mitral valve operations, demonstrating both safety and efficacy. Noonan syndrome is an autosomal-dominant multisystem disorder with variable expression and is the second most common syndromic cause of congenital heart disease, surpassed only by Down syndrome. A wide spectrum of cardiovascular phenotypes is associated with Noonan syndrome, including pulmonary valve stenosis (often with dysplastic valves), hypertrophic cardiomyopathy, secundum atrial septal defect and mitral valve abnormalities. Methods: Given the limited data in the literature regarding the experience of other centers with endoscopic mitral surgery in patients with this condition, we aim to present the case of a 46-year-old male with a known diagnosis of Noonan syndrome who presented to a cardiologist with a 6-month history of dyspnea and fatigue. Transthoracic echocardiography revealed severe mitral regurgitation. Following multidisciplinary discussions within the Heart Team and after obtaining informed consent from the patient and his family, the decision was made to proceed with totally endoscopic mitral valve repair. Results: The patient experienced an uneventful postoperative course and was discharged 8 days after the procedure. In this case, endoscopic surgery was essential for successfully repairing the mitral valve. Structural abnormalities, such as chest wall deformities causing heart malrotation and atypical positioning, significantly impaired visualization. Conclusions: The endoscopic approach provided superior access to the mitral valve, enabling precise and effective repair. Additionally, it offered benefits such as improved esthetic outcomes, faster recovery, and a reduced risk of exacerbating thoracic deformities due to improper sternal bone healing. Full article

Background: Intramural surgery techniques, particularly esophageal peroral endoscopic myotomy (E-POEM), gastric peroral endoscopic myotomy (G-POEM), and peroral endoscopic myotomy for Zenker’s (Z-POEM), have emerged as forefront minimally invasive endoscopic procedures. While several studies have reported on the outcomes in North America and Asia, evidence in the Middle East and North Africa remains limited. This study aims to evaluate the feasibility and safety of intramural surgery techniques within this region. Methods: This retrospective cohort study was conducted with approval from the institutional review board. All patients who underwent esophageal peroral endoscopic myotomy, gastric peroral endoscopic myotomy, and peroral endoscopic myotomy for Zenker’s from January 2016 to August 2023 were included. Results: In total, 119 patients underwent intramural surgery procedures during this period. The esophageal peroral endoscopic myotomy group had 81 (68%) patients, the gastric peroral endoscopic myotomy had 34 (28.6%) patients, and the peroral endoscopic myotomy for Zenker’s had 4 (3.4%) patients. The full cohort was 48.7% female, with a mean overall age of 40.5 years. The mean overall body mass index was 27.5 kg/m². The chief complaint was dysphagia (n = 80, 67.2%). All cases were successfully completed endoscopically. During the first 30 days, the most common complications were nausea/vomiting requiring admission (n = 4, 4.76%) and pneumomediastinum (n = 2, 2.38%). At a follow-up of 19 months, there were four mortalities; the causes of death were cardiac arrest (three cases) and end-stage prostate cancer (one case). Conclusions: Intramural surgery techniques are safe and technically feasible with low complication rates. Our study suggests that clinical success in the Middle East and Northern Africa population is comparable to larger international series. Full article

Background: Recently, minimally invasive access via right anterolateral mini-thoracotomy (RAMT) has been gaining popularity in cardiac surgery. This approach is also an option for surgeons performing aortic surgery. The aim of this study is to present our surgical method, highlighting the total endoscopic minimally invasive approach via RAMT for replacement of the ascending aorta (AAR) with or without involvement of the aortic root and the aortic valve. Methods: Clinical data of 44 patients from three participating institutions with AAR with or without involvement of the aortic valve or aortic root via RAMT between April 2017 and February 2024 were retrospectively analyzed. According to surgical procedure, patients were divided into two groups, in the AAR and in the Wheat/Bentall group with concomitant valve or root replacement. Operative time, length of ventilation, perioperative outcome, length of intensive care unit (ICU) as well as postoperative hospital stay, and mid- and long-term results were retrospectively analyzed. Results: Mean age was 61.4 ± 10.7 years old with a frequency of male gender of 63.6%. Mean cardiopulmonary bypass (CBP) time and aortic cross-clamping time was 94.9 ± 32.5 min and 63.8 ± 25.9 min, respectively. CPB and aortic clamp time were significantly lower in AAR group. In the first 24 h, the mean drainage volume was 790.3 ± 423.6 mL. Re-thoracotomy due to bleeding was zero. Sternotomy was able to be avoided in all patients. Patients stayed 35.9 ± 23.5 h at ICU and were discharged 7.8 ± 3.0 days following surgery from hospital. Mean ventilation time was 5.8 ± 7.6 h. All patients survived and 30-day mortality was 0.0%. At a median follow-up time of 18.2 months, all patients were alive. The results were similar in both groups. Conclusions: The full endoscopic RAMT approach with 3D visualization is a safe, feasible and promising technique that can be transferred in the field of aortic surgery without compromising surgical quality, postoperative outcomes, or patient safety when performed by an experienced team in a high-volume center.

(1) Background: The development of totally endoscopic aortic valve replacement has the potential to enhance clinical results compared to mini-sternotomy. To our knowledge, no comparison between these two techniques has been conducted before. Therefore, the objective of this retrospective study is to examine the results after both totally endoscopic and mini-sternotomy approaches. (2) Methods: This study covered all elective patients who underwent isolated aortic valve replacement, either totally endoscopically (n = 392) or through a mini-sternotomy (n = 323), between 2013 and 2021. Multivariable analysis was used to account for baseline variations between the two groups. All data were retrospectively gathered and analysed. The primary objective of this study was the one-year mortality rate. (3) Results: The mean aortic cross-clamping and cardiopulmonary bypass times were significantly longer in the totally endoscopic approach (cross-clamping: 43.73 ± 13.71 min and 61.93 ± 16.76 min, p-value < 0.001; CPB time: 64.86 ± 23.02 min and 93.23 ± 23.67 min, p-value < 0.001). However, perioperative bleeding was lower (706.40 ± 542.77 mL and 444.50 ± 515.84 mL, p-value < 0.001). The primary objective, one-year survival, did not significantly differ between both groups (Mini-AVR: 94.5% vs TEAVR: 93.3%, p-value = 0.520). (4) Conclusions: Our results show that totally endoscopic aortic valve replacement has comparable clinical results compared to aortic valve replacement through mini-sternotomy. Full article

Minimal-access cardiac surgery appears to be the future. It is increasingly desired by cardiologists and demanded by patients who perceive superiority. Minimal-access coronary artery revascularisation has been increasingly adopted throughout the world. Here, we review the history of minimal-access coronary revascularization and see that it is almost as old as the history of cardiac surgery. Modern minimal-access coronary revascularization takes a variety of forms—namely minimal-access direct coronary artery bypass grafting (MIDCAB), hybrid coronary revascularisation (HCR), and totally endoscopic coronary artery bypass grafting (TECAB). It is noteworthy that there is significant variation in the nomenclature and approaches for minimal-access coronary surgery, and this truly presents a challenge for comparing the different methods. However, these approaches are increasing in frequency, and proponents demonstrate clear advantages for their patients. The challenge that remains, as for all areas of surgery, is demonstrating the superiority of these techniques over tried and tested open techniques, which is very difficult. There is a paucity of randomised controlled trials to help answer this question, and the future of minimal-access coronary revascularisation, to some extent, is dependent on such trials. Thankfully, some are underway, and the results are eagerly anticipated. Full article

Patient-centred outcomes have grown in popularity over recent years in surgical care research. These patient-centred outcomes can be measured through the health-related quality of life (HRQL) without professional interpretations. In May 2022, a study regarding patient-centred outcomes up to 90 days postoperatively was published. Fourteen days after surgery, the HRQL decreased and returned to baseline levels after 30 days. Next, the HRQL significantly improved 90 days postoperatively. However, this study only focuses on a short-term follow-up of the patients. Hence, this follow-up study aims to assess the HRQL one year after totally endoscopic cardiac surgery. At baseline, 14, 30, and 90 days, and one year after surgery, the HRQL was evaluated using a 36-item short form and 5-dimensional European QoL questionnaires (EQ-5D). Using the 36-item short form questionnaire, a physical and mental component score is calculated. Over the period of one year, this physical and mental component score and the EQ-5D index value significantly improve. According to the visual analogue scale of the EQ-5D, patients score their health significantly higher one year postoperatively. In conclusion, after endoscopic cardiac surgery, the HRQL is significantly improved 90 days postoperatively and remains high one year afterward. Full article

Over the past years, minimally invasive procedures have been developed to reduce surgical trauma after cardiac surgery. The value of patient-centered outcomes, including the quality of recovery after hospital discharge, is increasingly recognized. Identifying meaningful changes in postoperative function that might have a negative impact on patients without noticeable complications can provide a more comprehensive understanding of the impact on the patient’s life. In total, 209 patients were included in this trial. Of these, 193 patients underwent totally endoscopic cardiac surgery, 8 underwent cardiac surgery through a sternotomy, and 8 underwent transcatheter aortic valve implantation. Patients who previously underwent cardiac surgery were excluded. Quality of life was determined through the Short Form 36 and European Quality of Life-5 Dimensions questionnaires before the surgery and 14, 30, and 90 days afterward. In patients who underwent totally endoscopic cardiac surgery, the quality of life improved over the three time periods. The different domains of the questionnaire evolved in a positive manner. However, 14 days postoperatively, a decline in quality of life was noted, followed by a return to baseline at 30 days and an increase at 90 days. In conclusion, totally endoscopic cardiac surgery improves the quality of life 90 days after surgery. Full article
