Insights
This study found that while angina is more frequent in aortic stenosis patients, coronary artery disease incidence is similar between aortic stenosis and failure. Current criteria for coronary arteriography in aortic valvulopathy are supported.

Abstract:
We have analyzed coronary arteriographies of 170 patients, 120 with isolated aortic stenosis and 50 with isolated aortic failure. Patients with stenosis showed higher frequency of angina (73% versus 54%, p = 0.0223). No significant differences were observed with respect to the incidence of the coronary artery disease (26.7% versus 31.8%, p = 0.18). The presence of angina was significantly more specific in aortic failure (specificity 52.4% versus 31.8% in aortic stenosis, p = 0.039). Among the patients with less than 56 years of age, the probability of developing coronary artery disease in absence of angina was 6.3% (1 out of 16), the confidence interval ranging from 1.5% to 30.2%. Our results do not support any modification of the conventional criteria for conducting coronary arteriographies in patients with aortic valvulopathy.
