Pseudoaneurysms of the mitral-aortic intervalvular fibrosa: survival without reoperation.

Background: the tissue spanning the mitral and aortic valves, the mitral-aortic intervalvular fibrosa (MAIVF), may be the site of pseudoaneurysm formation in the setting of infective endocarditis or congenital heart disease, or after valve surgery. Because of potential complications of MAIVF pseudoaneurysms, patients with such lesions are often referred for surgical repair.

Methods: we identified 3 individuals with MAIVF pseudoaneurysms who were followed without surgical intervention after diagnosis of the MAIVF pseudoaneurysm.
