Very high repair rate using minimally invasive surgery for the treatment of degenerative mitral insufficiency

Minimally invasive mitral valve surgery (MIMVS) is an established alternative to median sternotomy for mitral valve repair. However, this technique has yet to gain widespread adoption, partly because of concerns that this approach might yield lower repair rates or repairs that are less durable than those performed through a sternotomy. The purpose of this study was to report our inaugural experience with MIMVS, with a focus on mitral valve repair rate and midterm outcomes.
