Coronary-subclavian steal syndrome: an usual cause of refractory unstable angina.

ABSTRACT

A 73 year old woman, with previous history of coronary artery bypass grafting, was admitted for refractory unstable angina. The angiography revealed a significant stenosis of the ostium of the left subclavian artery. The patient underwent successful stenting of the subclavian artery and remained symptom free until hospital discharge a few days later.
