Apical Left Ventricular Pseudoaneurysm With Left‐to‐Right Shunt: A Rare Mechanical Complication of Myocardial Infarction Involving Both Ventricles

The pseudoaneurysm involving both ventricles is an infrequent complication following myocardial infarction. The diagnosis is complex and the condition carries a high risk of rupture. Transthoracic echocardiogram (TTE) and cardiac magnetic resonance (CMR) are crucial for diagnosis. We present the case of a 79-year-old man who underwent percutaneous coronary intervention (PCI) for acute myocardial infarction (AMI). Subsequent TTE revealed an apical pseudoaneurysm. To confirm the diagnosis and observe the progression, follow-up TTE and CMR were performed, confirming the pseudoaneurysm involving both ventricles with secondary left-to-right shunt. Surgical repair was performed, with postoperative TTE demonstrating the complete resolution of this shunt.
