Abstract:
Aorta-right atrial tunnel is a rare and distinct congenital anomaly. It is a vascular channel that originates from one of the sinuses of Valsalva with a tortuous course anterior or posterior to the ascending aorta, and terminates either in the superior vena cava or in the right atrium (RA). We report a 42-year-old female briefly with aorta-right atrial tunnel in which the left coronary artery arose from the tunnel and terminated into the RA.
