Abstract

Abstract: Introduction: Robotic cardiac surgery offers mitigated risks for obese patients requiring mitral valve surgery. We aimed to study the safety of robotic mitral surgery in the obese patient population by analyzing the outcomes of mitral surgery patients in our center for robotic cardiac surgery. Method: This study retrospectively included 123 consecutive patients who underwent robotic mitral valve operations in a single center for robotic cardiac surgery. Patients with body mass index (BMI) ≥ 30 were compared against patients with BMI < 30 for demographic and operative parameters as well as postoperative outcomes. Results: Mean BMI was 33.9 ± 2.8 in the obesity group ( n = 87) and 25.4 ± 2.7 in the no‐obesity group ( n = 36). Female gender (80.6% vs. 52.9%, p = .004), diabetes (25.0% vs. 10.3%, p = .036), and hypertension (48.6% vs. 26.4%, p = .018) were more common in patients with obesity. The obesity group was operated with similar cardiopulmonary bypass and total operative times with the no‐obesity group. Postoperative drainage and blood transfusion requirements were similar between the groups. Mechanical ventilation times (6.1 ± 2.2 vs. 8.0 ± 4.4 h, p = .003) and intensive care unit stay (20.4 ± 1.6 vs. 29.4 ± 3.7, p = .027) were shorter in the obesity group. Other postoperative outcomes of infection, atrial fibrillation, hospital stay duration, and readmission rates were similar between the groups. Conclusion: Robotic mitral surgery is safe to perform in obese patients. Obesity should not be a contraindication for robotic mitral surgery as obese patients have outcomes similar to nonobese patients despite increased challenges and risk‐factors.
