Overview of prevalence, trends, and outcomes of post myocardial infarction mechanical complications

Although infrequently encountered in contemporary clinical practice, post-acute myocardial infarction (AMI) mechanical complications are associated with considerable mortality and morbidity (1). These complications include free-wall rupture (FWR), ventricular septal rupture (VSR), and papillary muscle rupture (PMR) (2). As the landscape of AMI treatment has evolved over the past decades with a focus on reducing ischemic time and timely reperfusion via primary percutaneous coronary intervention (pPCI), the mortality rates related to AMI have declined (3). However, a similar decline in mortality rates associated with post-AMI mechanical complications has not been observed (4).
