Background: Currently obesity is accepted as a relative contraindication for robotic mitral valve operations. This study evaluates the perioperative outcomes of robotic mitral valve operations and examines the effect of obesity as a risk factor.Methods: Consecutive 123 patient who underwent robotic mitral valve operation with or without additional cardiac procedure were evaluated. The patients were examined in two groups according to the body mass index (BMI); Group A included patients with BMI> or = 30 (n=36) and Group B included patients with BMI<30 (n=87). Perioperative outcomes were recorded.Results: Mean BMI was 33,4 ± 2,8 in Group A and 25,1 ± 2,7in Group B. Mean age was 54 ± 13 in Group A and 50 ± 213 in Group B. Cardiopulmonary bypass time and cross clamp time were 130±32 vs. 140±46 and 83±21 vs. 90±28 minutes in Group A vs. Group B respectively (p>0.05). Postoperative mechanical ventilation time, drainage, need for blood transfusion were similar in both groups. Mean intensive care unit stay time and hospital stay time were 21±10 vs. 26±27 hours and 6,5±5 vs. 7,9±19 days in Group A and Group B respectively (p>0.05). One mortality and 2 hospital readmission were observed in Group A, there was no mortality and 1 hospital readmission in Group B (p>0.05). Conclusions: Outcomes of obese patients after robotic mitral valve operations are similar with non obese patients. Robotic mitral valve operations can safely be performed in obese patients.
