Key result
Minimally invasive mitral valve surgery is associated with ~87% freedom from 30-day major complications.
Why the study?
A systematic safety analysis of minimally invasive mitral valve surgery based on a comprehensive list of pre-specified 30-day complications defined by MVARC criteria was lacking.

Does minimally invasive mitral valve surgery through right mini-thoracotomy result in low 30-day major complications in patients with mitral valve pathology?
Minimally invasive mitral valve surgery is associated with a high rate of freedom from 30-day major complications (87.2%) and low mortality and stroke rates.
Ko et al. (2020) conducted an observational in mitral valve pathology (n=745). Minimally invasive mitral valve surgery was evaluated on composite of 30-day major complications based on MVARC definitions. Minimally invasive mitral valve surgery was associated with an 87.2% freedom from 30-day major complications, with an overall 30-day mortality of 1.2% and stroke rate of 0.3%.
