Coronaro-subclavial steal syndrome may develop as a rare complication of cardiac surgical revascularisation of the myocardium. Severe myocardial ischaemia may develop under certain circumstances if the internal mammary artery (IMA) is used as an arterial graft in aortic-coronary bypass surgery in the presence of haemodynamically significant subclavian stenosis. This is caused by the reversal of blood flow from LIMA to the subclavian artery. The authors present a case report of this syndrome in a patient with ventricular fibrillation as the first manifestation of this diagnosis.
