Case report describes successful surgical repair of a rare aorta-right atrial tunnel in a 36-year-old male patient, highlighting diagnostic and management challenges.
Congenital aorta-right atrial tunnel (ARAT) is a rare cardiovascular lesion and has a varied clinical presentation. Angiographically, these must be differentiated from relatively common entities such as ruptured sinus of Valsalva aneurysms and coronary-cameral fistulas. Management protocols vary depending on anatomical course/caliber of the tunnel and the status of the coronary ostia. We describe a case of a 36-year-old male patient who was diagnosed with this entity on computed tomography angiography and underwent successful surgical repair.
