Concomitant tricuspid valve repair in patients with minimally invasive mitral valve surgery

Background: The aim of this study was to investigate the 10-year Leipzig experience with minimally invasive mitral valve(MIMV) surgery in combination with tricuspid valve(TV) surgery. Methods: Between January 2002 and December 2011, a total of 441 patients with mitral valve(MV) dysfunction and concomitant TV regurgitation(TR) underwent MIMV surgery at the Leipzig Heart Center. The mean age was 68.7 +/- 10.0 years, mean LVEF was 56.7%+/- 13.1% and 184 patients(41.7%) were male. The Average logEuroSCORE was 8.3%+/- 7.2%, and patients had an average follow-up of 3.4 +/- 2.4 years. Results: Pre-discharge echocardiography showed no or mild mitral regurgitation(MR) in 95.1% and no or mild TR in 84.1%. Overall 30-day mortality was 4.3% with nineteen deaths. Five-year survival was 77.2%+/- 2.5%. Five-year freedom from TV-related reoperation was 91.0%+/- 1.8%. Conclusions: Our 10-year experience show that MIMV surgery in combination with TV surgery can be performed routinely with good peri-and post-operative results. Our observations support current recommendations to perform concomitant TV repair, particularly if tricuspid annular dilation is present.
