Abstract

Acute pericardial pathologies, such as pericardial effusion, pericarditis, and cardiac tamponade, have been reported rarely in patients presenting as ST-elevation myocardial infarction (STEMI). We present a series of 3 patients with STEMI, where an undiagnosed pericardial effusion led to pericardial tamponade and subsequent cardiocirculatory collapse. This is a case series of 3 patients, all women, aged 72, 64, and 54 years who presented to the emergency department with chest pain or syncope and were found to have STEMI with hemodynamic instability. They were taken to the catheterization laboratory for urgent coronary revascularization requiring mechanical circulatory support (intra-aortic balloon pump or impella). During catheterization, all 3 patients were diagnosed with large pericardial effusion using hemodynamic parameters and bedside transesophageal echocardiogram. Commonly ignored, pericardial tamponade and acute large pericardial effusion can be the cause of cardiocirculatory collapse. Two of the 3 patients survived with aggressive interventions requiring pericardial drains, long-term mechanical circulatory support, and effective postoperative rehabilitation. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: It is im...Continue Reading
