Quadricuspid aortic valve has been classified based on leaflet size. However, no association is seen between classification and severity of aortic regurgitation ( AR ). Bicuspid aortic valve is classified according to the number of cusps, with significantly higher prevalence of AR in cases with a raphe. We classified cases according to raphe number. In 1 patient with no raphe, AR severity did not change into the eighth decade. However, AR severity worsened in patients with a raphe, in 1 case requiring aortic valve replacement in the fifth decade. Unequal shear stress may lead to leaflet fibrosis and progressive AR .
