Abstract

Coronary subclavian steal syndrome (CSSS) is a coronary steal phenomenon secondary to subclavian artery stenosis in patients who have undergone coronary bypass surgery with the internal thoracic artery. Most commonly, CSSS is diagnosed angiographically. Our case emphasizes that stress ultrasound assessment using reactive hyperemia in the ipsilateral arm elicits a functional diagnosis of CSSS.
