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.
