Echocardiographic Diagnosis of Atrioventricular Septal Perforation Caused by an Aortic Valve Vegetation

Diagnosis of Left Ventricular Outflow Tract-Right Atrial Shunt Using Color Flow Doppler and Transesophageal Echocardiography

“…Perforation of the right or noncoronary cusp of the aortic valve with endo carditis can lead to a flow jet of aortic insufficiency which strikes the septum. This in turn may lead to vegetation formation or disruption of the membranous septum [12]. Pseudoaneurysms have been reported of the mitral-aortic intravalvular fibrosa with endocarditis and less frequently with the membranous septum [13,14].…”
