Operative strategies for acute mitral regurgitation as a mechanical complication of myocardial infarction

Abstract

Severe mitral regurgitation secondary to papillary muscle rupture is one of the mechanical complications after an acute myocardial infarction. Surgical strategies represent the cornerstone of treatment in this disease; in addition to surgical valve replacement, approaches involving surgical valve repair have been reported over time in different clinical scenarios to restore valve competency, improve cardiac function and reduce mechanical prosthesis-related risks. Moreover, in recent years, percutaneous trans-catheter procedures have emerged as an important alternative in high risk or inoperable patients.
