A Case of Severe Stealing Phenomenon (Regurgitation) in an Internal Thoracic Artery Graft Due to Excessive Blood Flow from the Ipsilateral Arteriovenous Fistula

〈Abstract〉 A 67(cid:514)year(cid:514)old male had undergone coronary artery bypass grafting (CABG) of the left anterior descending branch using the internal thoracic artery (ITA) three years ago. He presented with chest discomfort during an outpatient visit. The discomfort was caused by excessive blood flow through an arteriovenous fistula (AVF). Coronary angiography showed regurgitation into the ITA bypass graft (on the AVF side) and a high degree of stealing. The regurgitation disappeared after the AVF was closed, and the coronary stealing was ameliorated. We consider that the excess blood flow triggered the stealing phenomenon.
