Abstract:
The quadricuspid aortic valve is a very rare congenital malformation and usually presents with aortic insufficiency. Other associated congenital malformations have been described and particularly coronary anomalies have to be considered and investigated. We report the case of an intraoperatively diagnosed quadricuspid aortic valve in a 70 years old patient and discuss the clinical relevance of this rare congenital malformation.

Heart Valves
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...
