Double-orifice mitral valve is an rare anomaly characterized by a mitral valve with a single fibrous annulus and 2 orifices that open into the left ventricle. It is often associated with other congenital anomalies, most commonly atrioventricular canal defects, and rarely associated with a stenotic or regurgitant mitral valve. A patient who was diagnosed with congenital double-orifice mitral valve with severe mitral stenosis was treated successfully by percutaneous balloon mitral valvotomy rather than the conventional open surgical approach, demonstrating the utility of percutaneous correction of this anomaly.
双孔二尖瓣是一种罕见的心脏结构异常，其特征为二尖瓣具有单一纤维环和两个开口于左心室的孔口。它常与其他先天性异常相关，最常见的是房室通道缺损，很少与二尖瓣狭窄或反流相关。一名被诊断为先天性双孔二尖瓣伴严重二尖瓣狭窄的患者，成功接受了经皮球囊二尖瓣成形术治疗，而非传统的开放手术方法，这证明了经皮矫正这种异常的实用性。
