    BackgroundEuropean surgeons were the first worldwide to use robotic techniques in cardiac surgery and major steps in procedure development were taken in Europe. After a hype in the early 2000s case numbers decreased but due to technological improvements renewed interest can be noted. We assessed the current activities and outcomes in robotically assisted cardiac surgery on the European continent. MethodsData were collected in an international anonymized registry of 26 European centers with a robotic cardiac surgery program. ResultsDuring a 4-year period (2016-2019), 2,563 procedures were carried out {[}30.0\% female, 58.5 (15.4) years old, EuroSCORE II 1.56 (1.74)], including robotically assisted coronary bypass grafting (n = 1266, 49.4\%), robotic mitral or tricuspid valve surgery (n = 945, 36.9\%), isolated atrial septal defect closure (n = 225, 8.8\%), left atrial myxoma resection (n = 54, 2.1\%), and other procedures (n = 73, 2.8\%). The number of procedures doubled during the study period (from n = 435 in 2016 to n = 923 in 2019). The mean cardiopulmonary bypass time in pump assisted cases was 148.6 (63.5) min and the myocardial ischemic time was 88.7 (46.1) min. Conversion to larger thoracic incisions was required in 56 cases (2.2\%). Perioperative rates of revision for bleeding, stroke, and mortality were 56 (2.2\%), 6 (0.2 \%), and 27 (1.1\%), respectively. Median postoperative hospital length of stay was 6.6 (6.6) days. ConclusionRobotic cardiac surgery case numbers in Europe are growing fast, including a large spectrum of procedures. Conversion rates are low and clinical outcomes are favorable, indicating safe conduct of these high-tech minimally invasive procedures.

    An analysis of the learning curve for robotic-assisted mitral valve repair
    (WILEY, 2021-01-01) Gullu, Ahmet U.; Senay, Sahin; Kocyigit, Muharrem; Zencirci, Ertugrul; Akyol, Ahmet; Degirmencioglu, Aleks; Karakus, Gultekin; Ersin, Egemen; Karabiber, Alara; Alhan, Cem
    Background Many cardiac surgeons receive training for sternotomy-based cardiac surgical operations in residency programs and only a few education programs offer training specifically in minimally invasive cardiac surgery. In this report, we aimed to search and analyze the learning curve for robotic-assisted mitral valve (MV) repair in cardiac surgeons. Method Between January 2010 and July 2019, 60 robotic-assisted isolated MV repair surgeries were performed with DaVinci Robotic Systems in our center. Different kinds of surgical techniques were used. The assessment of the learning curve was based on cardiopulmonary bypass (CPB) and transthoracic aortic clamp (CC) times. Result There were 23 (38.3\%) men and 37 (61.7\%) women with a mean age of 48.3 years. The lesions of the MV were posterior leaflet prolapsus (n = 42, 70.0\%), anterior leaflet prolapsus (n = 8, 13.3\%), Barlow disease (n = 3, 5\%), and annular dilatation (n = 7, 11.6\%). The patients underwent notochordal implantation (n = 27, 45\%), quadrangular or triangular resection (n = 23, 38.3\%), isolated ring annuloplasty (n = 7, 11.7\%), resection, and leaflet reduction (n = 2, 3.3\%) or edge to edge repair (n = 1, 1.7\%). The maturation of the learning curve appeared to be about 30 cases. The statistical analysis showed that the mean CPB and CC times for the first 30 cases were greater compared with the 30 after learning curve (155.3 vs. 118.9 min {[}p = .00], 102.3 vs. 80 min {[}p = .00], respectively). There was no case of conversion to open surgery. No perioperative mortality was observed. Conclusion The maturation of the learning curve for robotic-assisted MV repair appeared to be about 30 cases in our group of patients. This study had encouraging results for surgeons who desire to start a robotic mitral surgery program.
