I was hospitalized with chest pain in 2008 and again last week. I am scheduled for a stress test this Fri. They did an echo with bubbles, the following are echo results. Mild concentric left ventricular hypertrophy . Right ventricle is borderline dilated. Injection of contrast documented an interatrial shunt . Mitral valve leaflets appear midly thicked. Trace tricuspid regurgitation. Trace pulmonic valvular regurgitation. Proximal ascending aorta is 4.3 cm AP. Borderline aortic root dilation.
