Mitral valve repair versus replacement: is it a different story for percutaneous compared to surgical valve therapy?

Abstract The complementary role of mitral valve repair versus replacement is based on evidence of long-term results in open surgery. Transcatheter mitral valve repair and replacement are both under rapid development but subject to clinical feasibility and first in-human short- and midterm outcome studies. The present article aims to review mitral valve repair and replacement by both techniques and to elucidate similar and potentially different aspects among the open and interventional approach.
