Urgent Open Atrial Transcatheter Mitral Valve Replacement as Bailout for Planned Surgery

JACC: Case Reports, 2020
Hybrid transcatheter mitral valve replacement (TMVR) has shown great promise for patients with severe mitral annular calcification. However, there have been limited reports of its use as a bailout for planned surgical MVR. Here, we present a bailout TMVR
