[Coronary lesions due to aortic valve disease. I -- Occurrence and clinical prognosis].
A multicentre retrospective study of 467 cases of operated aortic valve disease was undertaken to define the indications of coronary arteriography in the pre-operative work-up. Significant coronary artery disease was present in 15% of all cases or, more precisely, in 17% of cases with angina and in 8% when investigation was only routine. Coronary artery disease was more frequent in males, in patients with clinical or electrical evidence of previous myocardial infarction, in patients with ST-T wave changes, and when angina was severe (more than one attack per day). None of these factors was specific. It is therefore difficult to limit coronary arteriography to these patients or there would be a risk of missing significant lesions in a small number of cases. It is important to give the surgeon all the necessary information before aortic valve replacement and so coronary arteriography should be widely practiced in this context. However exceptions may be made for young patients and also those in congestive cardiac failure in whom coronary arteriography represents an unnecessary risk before surgery.
