Minimally Invasive Port Access Approach for Reoperations on the Mitral Valve.

摘要: Background In patients requiring a second-time or more operation on the mitral valve (MV), we assessed whether outcomes of minimally invasive port access approach (port group) were equivalent to those traditional redo sternotomy (redo group). Methods retrospective review (1998–2011), 409 had previous MV operations reintervention. Of those, 67 patients approach, and 342 the redo approach. latter, 220 met the inclusion criteria because emergencies, with endocarditis, concomitant procedures involving aortic aorta excluded. Results New York Heart Association class 2 above, age, atrial fibrillation, surgical indications similar in both groups. The group with repair (78% [n = 52] vs 41% [n = 90], p  = 0.4). re-repair rates (19% 10] 22% 20], 1). cardiopulmonary bypass times (153 ± 42 minutes 172 83 minutes, 0.07) cross-clamping (104 38 versus 130 71 0.5). postoperative stroke (3.0% 2] 3.2% 7], On echocardiography, freedom from regurgitation >2+ was 100% 99% group. mean hospital length stay 11 15 days 14 12 ( 0.07). Conclusions can be safely adopted for reoperations without compromising mortality function.
