Multimodality Imaging Assessment of Ischemic-Related Submitral Left Ventricular Pouch: A Case Report

Submitral left ventricular aneurysm remains a rare condition with a varied etiology besides the congenital origin. We describe the case of a 62-year-old male patient who presented, two weeks after an inferobasal myocardial infarction (MI), with dyspnea and atypical chest pain. Transthoracic echocardiography (TTE) and cardiac computed tomography (CT) revealed a giant thin-walled submitral left ventricular aneurysm. He was managed conservatively given the high operative risk. The overall survival was five months after discharge. Despite its rarity, recognizing the causal relationship between ischemic heart disease and submitral aneurysm can prevent life-threatening complications and is therefore of major importance. In the era of advanced imaging, multimodality cardiac imaging techniques are a key element for guiding diagnostic and therapeutic strategies.
