The mitral-aortic intervalvular fibrosa (MAIVF) is a fibrous, avascular region between the anterior leaflet of the mitral valve and noncoronary cusp of the aortic valve. This makes MAIVF vulnerable to injury and infection; thus pseudoaneurysm may develop. The pseudoaneurysm can cause compression to coronary arteries which causes angina or pulmonary artery resulting in pulmonary hypertension. We presented the pseudoaneurysm of MAIVF causing compression of superior vena cava and right atrium which was visualized by two- and three-dimensional transesophageal echocardiography and cardiac computed tomography.
