INCIDENCE OF QUADRICUSPID AORTIC VALVE AND THE DEVELOPMENT OF AORTIC REGURGITATION.
Aortic valve anomalies include unicuspid aortic valve, which is inherently stenotic; bicuspid aortic valve, which invariably progresses to aortic stenosis; and the rare quadricuspid aortic valve usually associated with aortic regurgitation, which we propose is related to advancing age.
In patients with isolated AS ([+ or -] AR) (only cardiac valve anatomically abnormal) the aortic valve may be unicuspid, bicuspid, tricuspid, or quadricuspid.

Quadricuspid aortic valve (QAV) is a rare congenital anomaly with the incidence rate of 0.
Because the anomaly of the quadricuspid aortic valve can also cause aortic stenosis, we performed cardiac catheterization to establish the main cause of the pressure gradient.
