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.
