Right coronary revascularization using the right internal thoracic artery in situ with persisting side branches.
There is a controversy about flow steal when the internal thoracic artery is used, with its remnant branches, to revascularize the coronary system. We report a case of a 64-year-old man who was submitted to revascularization using an in situ right internal thoracic artery, with persisting side branches, to supply the right coronary system. Angiography, Doppler echocardiography, and echocardiography at rest and under stress were performed. We found no evidence of flow steal.
