Left ventricular free wall rupture (LVFWR) is a rare but lethal complication of acute myocardial infarction (AMI). Urgent surgery is essential but associated with high postoperative mortality. Even worse, LVFWR patients may experience sudden death without a chance for surgery. In this article, we report our successful transcatheter closure of a patient with the most extensive pseudoventricular aneurysm after AMI reported thus far. Cardiac magnetic resonance imaging (MRI) revealed a giant pseudoventricular aneurysm located in the inferior and lateral walls of the left ventricle; the rupture diameter was 28 mm, and the maximum tumor diameter was 90.2 mm. We used transcarotid approach (TCA) and atrial septal defect closure umbrella to complete the operation, which solved the lack of special interventional instruments to treat pseudoventricular aneurysm after AMI. In addition, we still needed to treat liver and kidney failure caused by hemolysis after operation, and undergone strict follow-up. In conclusion, transcatheter closure is practical and feasible for the treatment of pseudoventricular aneurysm after AMI, although hemolysis and decline of cardiac pumping function after the successful interventional treatment deserve special attention. Future multicenter studies are required to identify patients best suited for interventional treatment timing. And further developments in devices and delivery techniques are required in order to optimize interventional outcomes.
