Coronary atherosclerosis in valvular heart disease.

To evaluate the usefulness of routine coronary arteriography in patients undergoing cardiac catheterization for the evaluation of valvular heart disease, we performed coronary arteriographic studies routinely in a series of 201 patients primarily catheterized for such evaluation. Coronary artery obstructive lesions in excess of 50% of the lumen were present in 45 of the 201 patients. In 18 of the 45 there was no history of chest pain. Three of the 18 had three vessels involved while 2 had two vessels involved. A total of 27 patients (13.4%) had luminal obstruction greater than 70%, and 9 of these had no pain. In 35 of the 201 patients, classic angina pectoris existed in the absence of radiographically significant disease. Severe coronary disease was found to coexist with hemodynamically severe valvular heart disease and was not predictable noninvasively.
