Successful surgical treatment of giant main coronary artery fistula connecting to right atrium.

Coronary artery fistulas are rare; they are defined as congenital or acquired coronary artery abnormalities in which blood is shunted into a cardiac chamber, great vessel, or other structure, bypassing the myocardial capillary network. We report here on a case of successful surgical treatment of a giant left main coronary artery fistula in a 29-year-old man who presented to our institution with exertional dyspnea. In this report, the different methods of management are also discussed and the indications for the surgical technique are briefly outlined.
