A case of echocardiographic evaluation of ruptured pseudoaneurysm of the mitral-aortic intervalvular fibrosa by infective endocarditis.
This report describes an unusual case of ruptured pseudoaneurysm (PSA) of mitral-aortic intervalvular fibrosa (MAIVF) caused by infective endocarditis. The PSA ruptured into the left sinus of Valsalva in addition to the left atrium, resulting in complicated shunting among the aorta, left ventricle and left atrium, leading to refractory heart failure. The transesophageal echocardiography provided the precise information concerning the anatomical detail of the PSA, which is crucial for the surgical repair. This is the first report describing a patient with PSA of MAIVF with two rupture sites.
