This report presents a 15 year review of the surgical treatment of 9 patients with congenital mitral stenosis seen at the Columbus Children's Hospital. The over-all mortality rate was 45 per cent. Seven patients had associated lesions, mostly coarctation of the aorta and patent ductus arteriosus. In the planning of the operative procedure, distal obstructive lesions of the left heart should generally be relieved first. The mitral valve should be explored with the use of cardiopulmonary bypass and the anatomic type of the valve determined. Type I valves will often respond to open valvulotomy, whereas Type II and III valves must be replaced.
本报告对哥伦布儿童医院收治的9例先天性二尖瓣狭窄患者的手术治疗进行了15年回顾。总体死亡率为45%。7例患者伴有其他病变，主要是主动脉缩窄和动脉导管未闭。在手术方案规划中，左心远端阻塞性病变一般应首先解除。应在体外循环下探查二尖瓣并确定瓣膜的解剖类型。I型瓣膜通常对直视瓣膜切开术有反应，而II型和III型瓣膜则必须进行置换。
