作者测定了单纯室间隔缺损(VSD)患者手术前、后的左室射血分数(LVEF)、左室形态及收缩末期左室壁张力与收缩末期容量之比(ESWS/ESVI),来评价左心室功能。材料与方法:受检者分为病人和对照二组。病人组77例均经心血管造影证实诊断。其中未手术的64例(年龄0.4～8.2岁),按左向右分流程度分大、中、小三组,其左向右分流量与肺循环量之比各为>50％(22例)、35～50％(24例)、 <35％(18例)。这三组年龄分别为0.8±0.1岁、8.4±0.4岁、5.6±0.4岁。手术治疗的13例(年龄0.4～1.2岁)术前均有症状,为大分流量,术后0.9～2.3年进行了心导管复查。对照组为27例川畸病患者,年龄为0.5～6.8岁,在急性期后0.3～1.3年作冠状动脉和左室造影,均无异常发现。
The authors measured left ventricular ejection fraction (LVEF), left ventricular morphology, and end-systolic left ventricular wall tension vs end-systolic volume ratio (ESWS / ESVI) in patients with simple ventricular septal defect (VSD) before and after surgery to assess left Ventricular function. Materials and Methods: Subjects were divided into two groups: patients and controls. 77 patients were diagnosed by cardiovascular angiography. Among them, 64 cases (aged 0.4 ~ 8.2 years) without surgery were divided into two groups according to their left-to-right shunting. The ratio of left shunt to pulmonary circulation was> 50% (n = 22) ~ 50% (24 cases), <35% (18 cases). The three groups of age were 0.8 ± 0.1 years old, 8.4 ± 0.4 years old, 5.6 ± 0.4 years old. Thirteen patients (0.4-1.2 years of age) undergoing surgery had symptoms preoperatively and had a maximal flow rate. Cardiac catheterization was performed 0.9 to 2.3 years after surgery. The control group was 27 cases of Kawasaki disease, aged 0.5 to 6.8 years old, with abnormal findings at 0.3 to 1.3 years after coronary artery and left ventricular angiography.
