Duplication of the tricuspid valve.
Duplication of the atrioventricular (AV) valves is a rare anomaly, more commonly seen in the mitral position. Only 13 cases have been reported in the literature.(1-10) The case described here represents an unusual variant of this anomaly and provides an opportunity to review the pathology and embryologic genesis of duplication deformities of the AV valves.
