A 73-year-old man with a history of coronary artery disease and inferoposterior myocardial infarction was referred for cardiology consultation with symptoms of chronic heart failure in NYHA class III.

Transthoracic echocardiography revealed a thrombus partially filling a giant pseudoaneurysm/aneurysm of the inferoposterior wall, causing significant deformation of the ventricular geometry (Figure 1; Videos 1–4). Despite the size of the aneurysm, the subvalvular mitral apparatus was intact, with no regurgitation. Given the uncertainty surrounding the differential diagnosis, cardiac magnetic resonance imaging was performed, which confirmed a giant ventricular aneurysm (long axis 6.7 cm) containing a thrombus (Figure 2; Videos 5 and 6), and anticoagulant therapy was begun. Myocardial perfusion scintigraphy excluded ischemia and confirmed necrosis of the inferoposterior territory. Preoperative cardiac catheterization showed chronic occlusion of the proximal right coronary artery but no significant left coronary disease, while ventriculography documented a large ventricular aneurysm (Figure 3; Video 7). The patient underwent surgical repair of the aneurysm of the left ventricular inferior wall (Figure 4) by partial aneurysmectomy under extracorporeal circulation, with removal of a large wall thrombus and closure of the aneurysm neck with a 2 cm × 3 cm Dacron® patch (Figure 4). The left ventricle was closed using continuous sutures. The postoperative period was uneventful and the patient was discharged home on the fifth postoperative day.
