ABSTRACT
Introduction:
The totally thoracoscopic approach for mitral valve (MV) disease is a minimally invasive method. We investigated the procedure’s feasibility, safety and effectiveness when it was performed by an experienced operator.
Methods:
We retrospectively analysed 96 consecutive patients with MV disease treated between March 2016 and November 2019 by minimally invasive procedures. The procedures were performed on a femoral artery-vein bypass through two ports, including a main operation port and a thoracoscopic port. The clinical data of patients were collected, including preoperative cardiac function, operative data, postoperative complications, and follow-up.
Results:
A total of 96 patients (57 male patients; average age, 49.7±14.5 years; left ventricular ejection fraction, 65.6±7.7%) were enrolled in this study. No intraoperative conversion incision or death occurred. The cardiopulmonary bypass and aortic cross-clamp times were 163.8±50.6 minutes and 119.7±38.9 minutes, respectively. Postoperative chest tube drainage in the first 24 hours was 232.8±108.1 ml. The ventilation time and length of intensive care unit stay were 13.2±6.2 hours and 2.9±2.2 days, respectively. One patient died of disseminated intravascular coagulation and prosthesis thrombosis 3 days after the operation, fearing anticoagulant-related hemorrhage. The overall success rate of valve repair during 1-year follow-up was 97.9%.
Conclusion:
The totally thoracoscopic procedure on mitral valves by an experienced surgeon is technically feasible, safe, effective and worthy of widespread adoption in clinical practice.
