Abstract
This is a case of a chronic left ventricular pseudoaneurysm after inferior myocardial infarction that remained clinically silent for 5 years before presenting with sudden rupture, leading to hemopericardium and cardiac tamponade. We discuss the importance of surveillance for left ventricular pseudoaneurysms, the limitations of echocardiography, and the critical role of computed tomography angiography imaging to establish the diagnosis and guide therapy. (Level of Difficulty: Beginner.).
