Quadricuspid aortic valve

Case contributed by Dr Vincent Tatco


Known case of aortic valve regurgitation with progressive shortness of breath.

Patient Data

Age: 60
Gender: Female

The aortic valve exhibits four equal-sized cusps (one right coronary cusp, one left coronary cusp and two non-coronary cusps) and calcifications.

Calcifications are also seen along the aorta and coronary arteries reflective of atherosclerotic disease. 

There is cardiomegaly with dilated left ventricle. 

Case Discussion

This case demonstrates a patient with quadricuspid aortic valve (QAV), which is a rare congenital valvular anomaly wherein there are four cusps, instead of the usual three, in the aortic valve.  In this case, the aortic valve is composed of four equal-sized cusps (type a QAV).  The most common complication of this valvular anomaly is aortic regurgitation due to inadequate closing of the four cusps during systole.
