Quadricuspid aortic valve associated with unruptured sinus of Valsalva aneurysm

Quadricuspid aortic valve is a rare congenital anomaly. It may present as an isolated anomaly but is occasionally associated with aortic regurgitation. Sinus of Valsalva aneurysm (SVA) is also an infrequent congenital anomaly, typically associated with tricuspid aortic valves. There are only a few reported cases of SVA (ruptured) associated with quadricuspid aortic valves in the literature. We report the first case of the association of quadricuspid aortic valve with an unruptured SVA in an adult patient.
