[Rare case of quadricuspid aortic valve].
Quadricuspid aortic valve is rare congenital anomaly. There are only 197 cases published in literature so far. That includes clinical and autopsy reports. This congenital anomaly occurs more often in pulmonary valve but function stays normal in 10 of lies. On the other side, in aortic position valve is malfunctioning in 50% of cases. Valve regurgitation is more likely to occur than stenosis In this kind of malformation, valves are prone to early dysfunction and endocarditis due to different valve architecture and unequal distribution of mechanical stress along valve cusps. Aortic valve replacement is indicated in younger population of these patients. This is a case report of rare congenital anomaly of big blood vessels--aortic valve with four cusps. This anomaly produced significant aortic regurgitation so this patient was indicated for aortic valve replacement.
