Inferior Wall ST-elevation Myocardial Infarction Complicated by Ventricular Septal Defect and Free Wall Pseudoaneurysm with Rupture

Abstract

Myocardial infarction (MI) is associated with complications in spite of appropriate management. The incidence of mechanical complications declined over time secondary to reperfusion therapies, improved control of blood pressure, the use of beta blockers and angiotensin-converting enzyme inhibitors, and aspirin. A high degree of suspicion is required, especially in elderly patients with complications post-PCI (percutaneous coronary intervention). Herein, we present a case of elderly male diagnosed with an inferior wall MI who had a PCI. He was found to have a post-infarction ventricular septal rupture (VSR) and basal inferior wall aneurysm that progressed over three weeks to a myocardial free wall rupture with hemopericardium. This case emphasizes the need for close monitoring of complications.
