Aortic insufficiency can be an [[acute]] illness or a [[chronic]] illness and the causes differ depending upon the acuity of the disease.  In general, aortic insufficiency is due to abnormalities of the [[aortic valve]] itself or the [[aortic root]].  Aortic regurgitation secondary to dilation of the [[ascending aorta]] has overtaken the valvular aortic disease as the most common cause of aortic regurgitation.

Overview

Aortic insufficiency can be an acute illness or a chronic illness and the causes differ depending upon the acuity of the disease. In general, aortic insufficiency is due to abnormalities of the aortic valve itself or the aortic root. Aortic regurgitation secondary to dilation of the ascending aorta has overtaken the valvular aortic disease as the most common cause of aortic regurgitation.[1]
