Key result
Minimally invasive thoracoscopic mitral valve replacement required longer cardiopulmonary bypass time than median sternotomy (P<0.001) but reduced hospital stay (P<0.001) without increasing mortality.
Why the study?
To compare surgical outcomes after mitral valve replacement via minimally invasive thoracoscopic surgery versus traditional median sternotomy, and determine short- and mid-term clinical outcomes.
Does minimally invasive thoracoscopic mitral valve replacement improve short- and mid-term clinical outcomes compared to traditional median sternotomy in patients undergoing mitral valve replacement?

Does minimally invasive thoracoscopic mitral valve replacement improve short- and mid-term clinical outcomes compared to traditional median sternotomy in patients undergoing mitral valve replacement?
Minimally invasive thoracoscopic mitral valve replacement is safe and effective, offering faster recovery and shorter hospital stays compared to traditional median sternotomy, despite longer operative times.
Liu et al. (2019) conducted an observational in Mitral valve replacement (n=404). Minimally invasive thoracoscopic (MIs) mitral valve replacement vs. Traditional median sternotomy (MS) was evaluated on Surgical outcomes and postoperative complications. Minimally invasive thoracoscopic mitral valve replacement required longer cardiopulmonary bypass time than median sternotomy (P<0.001) but reduced hospital stay (P<0.001) without increasing mortality.
