Different Outcomes in Two Cases of Papillary Muscle Rupture with Different Timings of Coronary Revascularization, Mechanical Circulatory Support, and Surgery

Abstract

Papillary muscle rupture is a rare but devastating complication following acute myocardial infarction (AMI). Although preventing the development of cardiogenic shock is important in such cases, the optimal multidisciplinary treatment approach is still not established. Here, we report two cases of papillary muscle rupture following AMI with different outcomes due to differences in the timing of coronary artery revascularization and mechanical circulatory support.
