Objective: Robotic total endoscopic coronary artery bypass grafting (TECAB) has been under development for 10 years. With increasing experience and technological improvement, double-vessel TECAB has become feasible. The aim of the present study was to compare the current outcomes of single- and double-vessel TECAB., Methods: Between 2001 and 2011, 484 patients underwent TECAB by 4 surgeons at 2 institutions. The median patient age was 60 years (range, 31-90), and the median European System for Cardiac Operative Risk Evaluation was 2 (range, 0-13). Single-vessel (n = 334) and double-vessel (n = 150) procedures were performed using the da Vinci, da Vinci S, and da Vinci Si robotic systems., Results: Compared with the single-vessel procedure, double-vessel TECAB required a longer operative time (median, 375 minutes; range, 168-795; vs median, 240; range, 112-605; P < .001) and had an increased conversion rate to a larger thoracic incision (31/150 [20.7%] vs 31/334 [9.3%]; P < .001). The median ventilation time was 10 hours (range, 0-288) for double-vessel versus 8 hours (range, 0-278) for single-vessel procedures (P = .006). The hospital stay was comparable, with 6 days (range, 2-27) for double-vessel TECAB and 6 days (range, 2-33) for single-vessel TECAB (P = .794). Perioperative mortality was 0.3% (1/334) with single-vessel TECAB and 2.0% (3/150) with double-vessel TECAB (P = .090). Freedom from major adverse cardiac and cerebral events at 5 years was similar after double- and single-vessel TECAB (73.5% vs 83.1%, P = .150). The 5-year survival was 95.8% and 93.9% (P = .708)., Conclusions: Double-vessel TECAB appears feasible and reproducible. The operative times were longer and the conversion rates to a larger thoracic incision were greater than with single-vessel TECAB. Also, the postoperative ventilation time was longer. Other perioperative morbidity and mortality and the recovery time and long-term clinical outcomes, however, were comparable., (Copyright © 2012 The American Association for Thoracic Surgery.

Objective: Robotically assisted totally endoscopic coronary artery bypass grafting (TECAB) is a viable option for closed chest coronary surgery, but it requires learning curves and longer operative times. This study evaluated the effect of extended operation times on the outcome of patients undergoing TECAB., Methods: From 2001 to 2009, 325 patients underwent TECAB with the da Vinci telemanipulation system. Correlations between operative times and preoperative, intraoperative, and early postoperative parameters were investigated. Receiver operating characteristic analysis was used to define the threshold of the procedure duration above which intensive care unit stay and ventilation time were prolonged. Demographic data, intraoperative and postoperative parameters, and survival data were compared., Results: Patients with prolonged operative times more often underwent multivessel revascularization (P < .001) and beating-heart TECAB (P =.023). Other preoperative parameters were not associated with longer operative times. Incidences of technical difficulties and conversions (P < .001) were higher among patients with longer operative times. Prolonged intensive care unit stay, mechanical ventilation, hospital stay, and with requirement of blood products were associated with longer operative times. Receiver operating characteristic analysis showed operative times >445 minutes and >478 minutes to predict prolonged (>48 hours) intensive care unit stay and mechanical ventilation, respectively. Patients with procedures >478 minutes had longer hospital stays and higher perioperative morbidity and mortality. Kaplan-Meier analysis revealed decreased survival among patients with operative times >478 minutes., Conclusions: Multivessel revascularization and conversions lead to prolonged operative times in totally endoscopic coronary artery bypass grafting. Longer operative times significantly influence early postoperative and midterm outcomes., (Copyright © 2012 The American Association for Thoracic Surgery. Published by Mosby, Inc.
