What are the perioperative outcomes and safety of minimally invasive mitral valve replacement through right minithoracotomy?
Minimally invasive mitral valve replacement through right minithoracotomy is a feasible and safe alternative to conventional sternotomy, with low mortality and morbidity.
Low mortality and short stay suggest feasibility in selected patients; leaves open need for RCTs versus sternotomy.
Background: Minimally invasive mitral valve replacement surgery (MIMVR) is gaining popularity for its multifold advantages. Here we report our single-institution experience with MIMVR through the right minithoracotomy over two years. Materials and Methods: This study was a retrospective analytical study. Forty-two patients undergoing MIMVR between August 2019 and July 2021 were included. Recorded perioperative data were collected and evaluated retrospectively. Results: A total of 42 patients were included in the study, of which 29 were females (69%). The mean age was 43.2+/- 8.2 years. Overall 30-day mortality was 2.38% (n = 1). Mean operating time, cardiopulmonary bypass, and aortic cross-clamp times were 264.9 ± 48.7, 151.5 ± 39.8, and 89.8 ± 25.6 minutes, respectively. Tricuspid valve annuloplasty was performed in 8 patients (19%). One patient (2.38%) required conversion to median sternotomy, and three patients (7.1%) underwent re-explorations due to bleeding. The median postoperative hospital stay was 5 days. Conclusions: MIMVR through right minithoracotomy is feasible, safe, and reproducible with low mortality and morbidity. Mitral valve surgery through a small anterior thoracotomy is a good alternative to conventional thoracotomy.

Gupta et al. (2022) conducted an observational in Mitral valve disease requiring replacement (n=42). Minimally invasive mitral valve replacement (MIMVR) through right minithoracotomy was evaluated on 30-day mortality. Minimally invasive mitral valve replacement through right minithoracotomy demonstrated a 30-day mortality rate of 2.38% and a median postoperative hospital stay of 5 days.
