The risk of coronary arteriography is considerably increased in patients who have left main coronary artery stenosis (LMCAS). Among 1,060 patients undergoing coronary arteriography over a three-year period, 83 were found to have LMCAS and three of these patients died (3.6 percent) during or shortly after the arteriographic procedure. Bypass surgery, however, can now be carried out at a very low risk irrespective of the degree of coronary disease present--there was no hospital mortality in 74 patients with LMCAS undergoing bypass surgery at our institution during this period. In addition to careful attention to detail, techniques that can minimize the risk of both of these procedures in patients with LMCAS include invasive hemodynamic monitoring and various pharmacologic manipulations to prevent myocardial ischemia. In a small percentage of patients, rest angina may prove refractory to inhospital medical treatment, and intraaortic balloon pumping may be necessary to stabilize the conditions of these patients before proceeding with arteriography and myocardial revascularization.
