Direct surgical transcatheter heart valve implantation in a calcified mitral valve.

Surgical transcatheter stent-valve implantation in severely calcific mitral valves represents a bail-out technique  for avoiding ventricular rupture and calcium embolization in patients with a high surgical risk profile. In this video tutorial, we present the transcatheter implantation of a valve in a severely calcific mitral valve annulus, under direct surgical vision, using an anchoring stitch technique to secure the stent-valve to the mitral annulus.
