Surgical patch repair using a prosthetic bypass graft is an effective treatment for left ventricular pseudo-pseudoaneurysm, a rare mechanical complication of myocardial infarction.
May inform rare post-MI pseudo-pseudoaneurysm repair; leaves open need for larger studies on durability.
We report a case of pseudo-pseudoaneurysm, which is a very rare complication of myocardial infarction. A 69-year-old man was admitted to our clinic with chest tightness and dyspnea. He had undergone aortic valve replacement with a pericardial bioprosthetic valve, ring mitral annuloplasty, and reconstruction of an aortic annular defect due to infective endocarditis with bovine pericardium 4 years prior. Echocardiography and computed tomography showed pericardial effusion and a 16-mm cavity at the anterolateral wall of the left ventricle. Magnetic resonance imaging suggested either pseudo-pseudoaneurysm or myocardial abscess. We successfully repaired the myocardial defect using a patch made from a vascular graft with pledgeted horizontal mattress sutures under cardiopulmonary bypass.

Kim et al. (2011) conducted a case report in Left Ventricular Pseudo-pseudoaneurysm with Hemopericardium (n=1). Surgical repair with a prosthetic bypass graft patch was evaluated on Clinical recovery and recurrence. Surgical repair of a rare left ventricular pseudo-pseudoaneurysm using a prosthetic bypass graft patch was successful, with no recurrence or abnormal wall motion at one month.
