Abstract
Chronic aortic valve disease involving stenosis, regurgitation or both is insidious and progressive. Severe valvular dysfunction may be present for years without symptoms, but functional deterioration is often rapid once congestive heart failure, angina or syncope with effort is present. As the severity of aortic stenosis may not be easy to assess clinically, the relative usefulness of various tests is considered in this paper. The difficulty with chronic aortic regurgitation lies not in diagnosing the problem but in detecting early left ventricular dysfunction in time to perform the surgery that can prevent further functional deterioration. Patients with significant aortic valve disease should undergo surgery when the important symptoms of dyspnea, angina or syncope with effort first appear. Surgery should also be considered in selected patients with aortic regurgitation in whom left ventricular function has diminished even without symptoms.
