title: Quadricuspid aortic valve.
abstract: A rare case of a quadricuspid aortic valve discovered incidentally at autopsy is described. A shallow raphe joined the supernumerary and adjacent cusp, possibly representing early fusion of the commissures. There was no symptomatic hemodynamic abnormality. Other than a probe-patent foramen ovale, no congenital anomalies were present. This is only the sixth example of a quadricuspid aortic valve with a raphe reported in the English language literature.
