【摘要】 目的 单心室临床表现颇复杂,为提高临床诊断准确率,我们分析73例单心室的临床特征。方法 分析73例单心室的心电图、超声心动图、心血管造影和手术所见,以探讨临床特征与形态学关系。结果 73例中,A型单心室61例,B型4例,C型8例;6例单心室并单心房,其中5例并心脏异位;61例存在房间交通;58例有二组房室瓣;15例为一组房室瓣;71例存在多处肺动脉狭窄。结论 单心室易并存多种心内畸形及心脏异位,手术前仔细观察心内各部位结构,有利于诊断和手术方式的选择。 【关键词】 心脏缺损,先天性 临床特征
Clinical features of single ventricle in 73 cases Shi Ljiang, Zhu Xianyang, Deng Dongan, et al. Shenyang General Hospital, PLA, Shenyang 110015 【Abstract】 Objective Single ventricle (SV) appears complex on clinical features. Clinical features in 73 cases of SV were studied in order to improve the diagnosis of SV.Methods Electrocardiogram, ultrasound cardiograph, cardioangiograph and operative finding in 73 cases of SV were analyzed.Results Sixty one cases were of type A, 4 of type B and 8 of type C. No case of type D was found in this series. Five of the 6 cases of SV with single atrium were complicated by malposition of the heart. Atrial communications were present in 61 cases. Double atrioventricular valves were detected in 58 cases and single atrioventricular valve in 15 cases. Multiple pulmonary stenoses were present in 71 cases. Conclusion SV is frequently associated with other intracardiac malformation and malposition so a careful preoperative study on the intracardiac structures is very helpful for the diagnosis and operation. 【Key words】 heart defects, congenital clinical feature
单心室是指三尖瓣和二尖瓣或共同房室瓣开放到单一心室腔(可有或无肺动脉狭窄)的一种复杂先天性心血管畸形,临床较为少见。此病易合并多种畸形和心脏异位,临床诊断困难。为提高单心室诊断准确率,我们分析73例单心室的心电图、超声心动图、心血管造影和手术所见,以探讨临床特征与形态学关系。
材料和方法
73例中,男48例,女25例,年龄2.5~34岁,其中2.5~14岁64例,15~34岁9例。均有完整的心电图、胸片、超声心动图资料,经右心房和单一心室造影确诊,其中48例手术证实诊断。按Van Praagh等[1]分类法将单心室分四种类型:A型:单纯左心室有右心室漏斗腔;B型:单纯右心室可有小的左心室;C型:两心室形态结构而无室间隔;D型:只有一个漏斗腔,而无左右心室体部。每一型又根据大血管关系再分I、II、III型。I型:大血管关系正常,II型:大血管右转位;III型:大血管左转位。
结果
