Repair Versus Replacement in Mitral Valve Papillary Muscle Rupture: A Multicenter Study.

ABSTRACT:

Objectives

Papillary muscle rupture (PMR) is a rare but potentially fatal mechanical complication after acute myocardial infarction (AMI). Although surgery is considered the gold-standard treatment for post-AMI PMR, the optimal surgical strategy remains unclear.

Methods

Data from post-AMI PMR patients submitted to mitral valve replacement (MVR) or mitral valve repair (MVr) surgery in the period between 2001 and 2019, from 20 international centres, were collected in the CAUTION study database. In-hospital and long-term post-discharge mortality were the endpoints. A multivariable logistic regression model was used to determine mortality independent factors.

Results

The patient cohort available included 218 patients. MVR was the most frequent type of surgery (81.6%). Com
