Incidence
The incidence of aortic insufficiency in the elderly is low in comparison to the incidence of aortic stenosis and mitral regurgitation[1]. Majority of elderly patients have combined aortic stenosis and aortic insufficiency and the incidence of pure aortic insufficiency is rare[2].
Etiology
Acute aortic insufficiency in elderly is due to either aortic dissection or infective endocarditis . Chronic aortic insufficiency is due to hypertension or calcific aortic stenosis or a bicuspid aortic valve causing ascending aorta dilatation with resultant aortic insufficiency.
Treatment
The goal of surgery is to improve quality of life, hence presence of symptoms is the most important guide to determining whether or not aortic valve repair be performed. However, asymptomatic chronic aortic insufficiency with evidence of marked left ventricular dilatation or left ventricular dysfunction is often recommended prophylactic aortic valve repair[3]
