The mitro-aortic intervalvular fibrosa (MAIVF) connects the anterior mitral leaflet to the posterior portion of the aortic annulus. The pseudoaneurysm of MAIVF is one of the uncommon but catastrophic complications of native or prosthetic aortic valve endocarditis or chest trauma. We report a case of infective endocarditis of mitral valve complicated by development of pseudoaneurysm of MAIVF, and fistulous formation causing massive shunt flow from the ascending aorta above the non-coronary cusp to the left ventricle outflow tract. © 2012 King Saud University.
