Abstract

Aorta-right atrial tunnel is a vascular anomaly that originates from the aortic sinus and terminates in either the superior vena cava or the right atrium. The patency of the tunnel can result in volume overload in both ventricles, bacterial endocarditis, aneurysm formation, and spontaneous rupture. Transesophageal echocardiography was performed in a 42-year-old male patient diagnosed with infectious endocarditis, and vegetation of the mitral and aortic valves, right atrial enlargement, and an extracardiac blood vessel connecting the aorta to the right atrium were discovered. Therefore, we were able to diagnose an aorta-right atrial tunnel leading to infectious endocarditis and proceeded with surgical treatment. Together with a review of the literature, we present a case report of a patient with aorta-right atrial tunnel accompanied by infectious endocarditis.
