Three cases of subaortic stenosis due to accessory mitral tissue are presented. The diagnosis of the cause of obstruction was correctly established in each child before surgery, by 2D echocardiography and cineangiography. Resection of the accessory mitral tissue through a simple aortotomy gave excellent results. The eight previously published cases are discussed, emphasising the importance of accurate preoperative diagnosis. The cause of obstruction is difficult to determine at surgery, which may have disastrous consequences, whilst simple resection of the abnormal tissues leads to a complete and definitive cure.
本文报告了3例因二尖瓣附属组织导致的主动脉瓣下狭窄病例。通过二维超声心动图和心血管造影，在术前正确诊断出了每个患儿的梗阻原因。通过简单的主动脉切开术切除二尖瓣附属组织，取得了良好的效果。文中讨论了之前发表的8例病例，强调了准确术前诊断的重要性。梗阻原因在手术中很难确定，这可能会带来灾难性后果，而简单切除异常组织则可实现完全且明确的治愈。
