Ventricular Rupture With Pseudoaneurysm Causing Compression Effect on the Right Ventricular Cavity

Left ventricular pseudoaneurysm (LVPA) typically results from incomplete rupture of the ventricular wall. Here we describe the case of a 79-year--old patient who presented with acute chest pain, was found to have acute anterior and inferior ST-segment elevation myocardial infarction, and was accidentally discovered to have a subacute LVPA creating compression effect on the right-sided cardiac chambers. A multidisciplinary team promptly decided to proceed with surgical repair. This case highlights the varied presentations of LVPA, which can easily be overlooked during the initial evaluation. The use of multimodality imaging played a crucial role in the timely diagnosis and management of this condition.
