A 2-week-old newborn girl underwent successful surgery in our clinic for critical subaortic stenosis caused by accessory mitral valve tissue, which, because of excessive growth, protruded into the left ventricular outflow tract. The preoperative pressure gradient below the aortic valve was 80 mm Hg. The operation consisted of resection of the accessory tissue through a combined aortotomy and atriotomy approach without residual pressure gradient and mitral valve incompetence. This approach is recommended to ensure that accessory tissue is removed without damaging the mitral valve.
一名2周大的新生女婴在我们诊所接受了成功的手术，治疗由副二尖瓣组织引起的严重主动脉瓣下狭窄，该组织因过度生长而突入左心室流出道。术前主动脉瓣下方的压力梯度为80毫米汞柱。手术包括通过联合主动脉切开术和心房切开术切除副组织，术后无残余压力梯度和二尖瓣关闭不全。建议采用这种方法以确保在不损伤二尖瓣的情况下切除副组织。
