Answer

Exclusion of coronary artery disease by coronary angiography is important in all patients older than 35 years who are being considered for valve surgery. Coronary angiography should also be performed in patients younger than 35 years if they have LV systolic dysfunction, symptoms or signs suggestive of coronary artery disease, or 2 or more risk factors for premature coronary artery disease, excluding gender. Generally, the incidence of associated coronary artery disease has been reported to be 50% in patients with aortic stenosis who are older than 50 years. Coronary angiography need not be performed in young patients with no atherosclerotic risk factors and in circumstances where the risk involved outweighs the benefits. [5]
