Item Percutaneous cannulation for cardiopulmonary bypass in robotic mitral valve surgery with zero groin complications(WILEY, 2022-01-01) Bastopcu, Murat; Senay, Sahin; Gullu, Ahmet U.; Kocyigit, Muharrem; Alhan, CemIntroduction Robotic valve surgery utilizes the femoral vessels to set up cardiopulmonary bypass (CPB) which translates to groin wound and lower extremity vascular complications. A less invasive technique is a totally percutaneous bypass using vascular closure devices (VCDs) with concerns for lower limb ischemia and arterial stenosis. Since April 2018, we have adopted the standard use of total percutaneous CPB in our robotic mitral cases. We report our institutional results with this technique. Methods All consecutive patients who underwent robotic mitral valve surgery between April 2018 and December 2020 in our institution were included in our study. Hospital database data on demographics, operative variables, and surgical outcomes were recorded and analyzed. Results Robotic mitral valve surgeries were performed on 32 consecutive patients (mean age 57.2 +/- 14.8) between April 2018 and December 2020. None of our patients developed an infection at any site. Seroma, hematoma, or pseudoaneurysm were not observed at puncture sites. Surgical repair of the femoral vessels or an additional VCD was not necessary for any of our patients. Patients were followed up for a mean duration of 23.5 months. Our patients did not present with a late wound infection, a seroma, or a pseudoaneurysm, nor had complaints of limb ischemia or claudication. Conclusion Total percutaneous bypass is the least invasive method of establishing extracorporeal circulation for cardiac surgery and can be performed with excellent results. The benefits of robotic surgery can be expanded with better results in groin cannulation by the adoption of total percutaneous CPB.Item 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, CemBackground 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.
