Left ventricular pseudoaneurysm repair utilizing P2 segment of mitral valve: a case report

Abstract

Abstract Background Left ventricular (LV) pseudoaneurysms are a rare occurrence typically seen after myocardial infarction (MI) or in patients with prior cardiac surgery and are associated with a significant risk of rupture and mortality. Management includes primary repair, epicardial patching, or percutaneous repair with occlusive devices. Case presentation This case report describes a 46-year-old male with a large LV pseudoaneurysm that was surgically patched with a segment of his mitral valve. To our knowledge, there has not been a documented repair utilizing a segment of the mitral valve. Conclusions The applicability of this technique is limited to cases with posteriorly located pseudoaneurysms near the mitral valve, thus allowing the P2 segment to be used as a patch. This is a novel approach to LV pseudoaneurysm repair, though careful consideration towards patient selection is warranted, as comorbid conditions may contribute to morbidity and mortality.
