When the Heart Holds Its Own Rupture: A Case Report of a Clinically Silent Left Ventricular Pseudoaneurysm Following Myocardial Infarction.

Left ventricular pseudoaneurysm is a rare but potentially fatal mechanical complication of acute myocardial infarction, often associated with a non-specific clinical presentation and a high risk of rupture. We report a case of a patient who developed a left ventricular pseudoaneurysm following an acute myocardial infarction that initially remained undiagnosed. The lesion was incidentally identified during follow-up imaging. Multimodal imaging confirmed the diagnosis and guided urgent surgical management, resulting in a favorable outcome. Left ventricular pseudoaneurysm remains a diagnostic challenge due to its non-specific presentation. Early recognition using multimodal imaging and timely surgical intervention are essential to prevent catastrophic outcomes.
