Left ventricular (LV) pseudoaneurysms are a rare occurrence that may be seen after myocardial infarction (MI) or in patients with prior cardiac surgery and are associated with a significant risk of rupture and mortality rate. Repair options include primary repair, epicardial patching, or percutaneous repair with an occlusive device. To our knowledge, there has yet to be a repair utilizing a segment of the mitral valve, which we have demonstrated in this case report. Unfortunately, the patient in this case later expired after complications of mesenteric ischemia. The application of this technique is limited to cases in which the pseudoaneurysm is posteriorly located and in close proximity to the mitral valve so that the P2 segment may 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.
