Directional coronary atherectomy for coronary artery spasm refractory to medical therapy.
A patient with severe medically refractory coronary artery spasm was treated successfully with coronary atherectomy of a mild (40%) left anterior descending artery stenosis. Before the procedure, the patient was dependent on intravenous nitroglycerin because of daily episodes of angina with ST-segment elevation despite receiving multiple combinations of antianginal therapies. Clinical response to coronary atherectomy was prompt and dramatic.
