Transcatheter Mitral Valve Repair in Acute and Critical Cardiac Conditions.

Acute mitral valve regurgitation (MR) is an emergency condition that requires an early diagnosis of the etiology and rapid management. Surgical intervention is the first-line treatment for acute severe MR. However, many patients are denied surgical intervention due to the acute risk of surgery. Transcatheter mitral valve repair (TMVr) is a less invasive technique and becoming a potential alternative to surgery in inoperable patients but is underrepresented in the literature. This review aims to discuss the published data on the use of TMVr in unstable MR patients presenting with acute or critical cardiac conditions.
