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.
房室（AV）瓣重复是一种罕见的异常情况，更常见于二尖瓣位置。文献中仅报道过13例。（1 - 10）此处描述的病例代表了这种异常的一种不寻常变体，并提供了一个回顾房室瓣重复畸形的病理学和胚胎发生学的机会。
