This paper reports on two cases of more uncommon types of subaortic stenosis. A 2-year-old boy was found with accessory mitral valve leaflet (AMVL) attaching to the anterior leaflet, ballooning into the subaortic ventricular septum associated with a discrete subaortic membrane. The obstruction was successfully relieved by removal of the AMVL and resection of the membrane. A 19-day-old newborn with accessory tissue on the mitral valve (AMVT) causing subaortic stenosis, subaortic ventricular septal defect (VSD) and patent ductus arteriosus was operated on successfully. Accessory tissue excision through the VSD, VSD patch closure and ductus ligation were performed.
本文报道了两例较为罕见类型的主动脉瓣下狭窄病例。一名2岁男孩被发现有副二尖瓣叶（AMVL）附着于前叶，膨入主动脉瓣下室间隔，伴有一个离散的主动脉瓣下隔膜。通过切除AMVL和切除隔膜，梗阻得以成功解除。一名19天大的新生儿因二尖瓣上的副组织（AMVT）导致主动脉瓣下狭窄、主动脉瓣下室间隔缺损（VSD）和动脉导管未闭，手术成功。通过室间隔缺损进行副组织切除、室间隔缺损补片修补和动脉导管结扎。
