Robotic Mitral Valve Repair for Anterior Leaflet and Bileaflet Prolapse

摘要: Background Centers have expanded indications for robotic mitral valve repairs to include complex pathologic features. We studied our results after repair anterior leaflet or bileaflet prolapse. Methods Data were collected contemporaneously on 289 patients operated from May 2000 September 2006. Every patient underwent preoperative transesophageal echocardiography. Follow-up consisted of serial echocardiograms, clinic visits, and phone conversations with their physicians. Results A total 66 (anterior leaflet, n=14; bileaflet, n=52) identified. Mean age was 52.6 ± 7.1 years, 57 (86%) had New York Heart Association functional class II III symptoms. Cardiopulmonary bypass cross-clamp times 171 52 132 39 minutes, respectively. The 30-day late mortality rates 3% (n = 2) each time point. There no device-related perfusion-related complications sternotomy conversions. Complications included 2 strokes (3%), bleeding reexplorations 10 pleural effusions requiring intervention (15%). length hospital stay surviving 5 3 days, extubation averaged 9.5 13 hours. 6 (9%) required reoperation. follow-up 795 495 echocardiographic regurgitation 60) none trace 35, 58.3%), mild 19, 31.6%), moderate 2, 3.3%), severe 4, 6.7%). Conclusions Robotic prolapse is feasible safe. Outcomes degree are similar series using conventional techniques. Long-term formally address the efficacy
