OBJECTIVE: The aim of our study is to evaluate outcomes of minimally invasive mitral valve replacement (MIMVR) through a right minithoracotomy in patients with rheumatic mitral valve disease. METHODS:Between January 2005 until june 2018, a total of 198 patients underwent minimally invasive mitral valve replacement (MVR) with (135) 68% isolated MV surgery and (63) 32% with concomitant Tricuspid valve (TV) surgery underwent MIMVR surgery at King Fahad Armed Forces Hospital (KFAFH).. The mean age was 35 ± 15 years and mean LVEF was 45.6%± 7.2 % . The Average logistic EuroSCORE was 6.3%± 3%, patients had an average follow-up of 36± 12 months . RESULTS: Intra-operatively patient had a mean bypass time 75 ± 20 min , cross clamp time 60 ± 10 min and conversion to sternotomy 1% in 2 patients . Overall in-hospital mortality was 1.5 % with 3 in-hospital deaths , mean ICU stay 4 ± 2 days (d) and length of stay (LOS) 7± 2 d . Stroke rate was 0.5% in 1 patient , no lower limb ischemia and 4 % 8 patients with groin wound infection . 4 years follow up showed functional class NYHA I in 90% II in 6% III &IV IN 4%, freedom from MV-related reoperation was 97.4% and survival was 95%. CONCLUSIONS: Our experience in MIMVR for patients with rheumatic mitral valve disease showed that it is both a safe and effective with excellent short , midterm outcomes with improved patient satisfaction and recovery .
