Coronary subclavian steal syndrome is a rare cause of recurrent angina after coronary artery bypass grafting. Identification of the myocardial ischemic region is crucial because it guides revascularization interventions to improve symptoms and myocardial ischemia. Positron emission computed tomography (PET) with rubidium might be a helpful tool because it identifies ischemia, localizes more precisely the ischemic region, and evaluates coronary flow reserve. Here, we report a case of recurrence of angina after coronary artery bypass grafting caused by an obstruction in the left subclavian artery and consequently by coronary steal syndrome confirmed by PET.
