Concomitant tricuspid valve repair during minimally invasive mitral valve surgery demonstrates good peri- and post-operative outcomes, supporting current guideline recommendations.

May support concomitant tricuspid repair during minimally invasive mitral surgery; leaves open need for randomized confirmation of benefit.
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.

Pfannmüller et al. (2013) conducted a cohort in Mitral valve dysfunction and concomitant tricuspid valve regurgitation (n=441). Minimally invasive mitral valve surgery with concomitant tricuspid valve surgery was evaluated on 30-day mortality. Minimally invasive mitral valve surgery combined with tricuspid valve surgery was associated with a 30-day mortality of 4.3% and a 5-year survival of 77.2%.
