Objective:
To summarize the surgical experience with robotic mitral valve replacement (MVR) over the last 6 years and demonstrate the clinical follow-up results.
Methods: From 2008 to 2014, a total of 44 patients underwent robotic mitral MVR with da Vinci Surgical System (Intuitive Surgical, USA) in our center. The patients’ average age was 45±13 years with male to female ratio 0.9. The median heart function was NYHA class II and 46.5% had atrial fibrillation. Rheumatic mitral stenosis (MS) was diagnosed in 74.3% of the patients. Mechanical or bioprosthetic valve was replaced via left atriotomy. Radiopaque titan clips was applied by Cor-Knot knot-tying device (LSI Solutions, Inc, Victor, NY) to anchor the valve. The patients were followed at outpatient clinic regularly out to 6 years.
Results: All cases were performed successfully by the same surgeon. No conversion to median sternotomy or operative mortality occurred. The operation time was 292±62 minutes (ranged, 140 to 450 minutes) with CPB time 125±27 minutes and aorta cross-clamping time 88±21 minutes. The mechanical ventilation was continued for 15±6 hours postoperatively. No myocardial infarction, ventricular tachycardia or excessive bleeding was complicated. All patients were successfully followed for a median of 4 years (range, 1 month to 6 years). No death, stroke, re-operation was reported and 39.5% of the patients still had atrial fibrillation.
Conclusions: Robotic MVR is a safe and effective procedure with excellent long term surgical outcome.
