Saphenous vein-internal mammary bypass links to anteroseptal MI alongside angina and arrhythmia relief.
Case Report (n=1)
Aortocoronary bypass surgery, complicated by an anteroseptal myocardial infarction, provided relief of medically refractory variant angina and ventricular arrhythmias in a young man.
May relieve refractory variant angina despite perioperative MI in select cases; leaves open any role in current practice.
A 30-year-old man with variant angina pectoris and ventricular arrhythmias had an angiographically demonstrable 60% obstructive lesion of the proximal left anterior descending coronary artery that was observed to progress to 100% during spasm. Control of pain and arrhythmia by pharmacologic means was unsuccessful. Aortocoronary saphenous vein-internal mammary coronary bypass was associated with an anteroseptal wall myocardial infarction and relief from both angina pectoris and arrhythmias. It is suggested that infarction of the ischemic myocardium played a role in the successful management of this case.

Charles A. Marsh (1976) conducted a case report in Variant angina pectoris and ventricular arrhythmias (n=1). Aortocoronary saphenous vein-internal mammary coronary bypass was evaluated on Relief from angina pectoris and arrhythmias. Aortocoronary saphenous vein-internal mammary coronary bypass was associated with an anteroseptal wall myocardial infarction and relief from both angina pectoris and arrhythmias.
