Abstract:
An 83-year-old woman with a history of coronary artery disease presented with anterior ST-elevation myocardial infarction. During coronary intervention, she was found to have a ventricular septal rupture, but was felt not to be a surgical candidate due to advanced shock. She was offered transcatheter repair using an Amplatzer post-infarction muscular ventricular septal defect occluder and recovered completely. She was discharged, but returned four months later with chest pain. A cardiac CT and contrast-enhanced echocardiogram revealed a left ventricular pseudoaneurysm. She underwent transcatheter repair using an Amplatzer Vascular Plug II and recovered without further sequelae.
