ABSTRACT
This case report delineates the clinical trajectory and management strategies of a 59-year-old Hispanic male diagnosed with a left ventricular pseudoaneurysm (LVPA) following a delayed presentation of ST-segment elevation myocardial infarction (STEMI), for which reperfusion treatment was not administered. Initially, an echocardiogram demonstrated an extensive anterolateral myocardial infarction, severe left ventricular systolic dysfunction, and an early-stage left ventricular apical aneurysm with thrombus, leading to the initiation of warfarin. Metabolic myocardial perfusion imaging via positron emission tomography indicated a substantial myocardial scar without viability, guiding the decision against revascularization. Post discharge, the patient, equipped with a wearable cardioverter defibrillator for sudden cardiac death prevention, experienced symptomatic ventricular tachycardia, which was resolved with defibrillator shocks. Subsequent imaging revealed an acute LVPA adjacent to the existing left ventricular aneurysm. Given the high surgical risk, conservative management was elected, resulting in thrombosis and closure of the pseudoaneurysm after two weeks. The patient eventually transitioned to home hospice, surviving an additional five months. This report underscores the complexities and therapeutic dilemmas in managing post-MI LVPA patients who are ineligible for surgical intervention.
