Abstract
In the immediate postoperative period, echocardiography was used to study left ventricular function in 69 children after correction of various congenital cardiac malformations. Left ventricular contractility indices and systolic time intervals measured from aortic cusp echoes were repeatedly obtained during the fist postoperative week. The degree of impairment of left ventricular function was assessed for different diagnostic groups and are tabulated. Decrease in left ventricular function was strongly correlated to operating time, cardiac bypass time, and aortic clamping time, the most important factor being cardiac bypass time. Left ventricular ejection time (LVET) was the most useful parameter of cardiac function in the immediate postoperative period and was of prognostic value in 5 patients who died early in that period. Abnormal septal movement was seen in most patients, but usually normalized within 2 wk. After extensive operations, changes in the movement pattern of the aortic leaflets were also seen. Although pericardial effusion was commonly found during the postoperative period, it did not indicate postcardiotomy syndrome and disappeared spontaneous within 2 mth.
本文采用超声心动图对69例小儿先天性心脏畸形矫治后的左心室功能进行了研究。术后第一周反复测量左心室收缩指数和主动脉瓣尖回声测量的收缩时间间隔。评估不同诊断组的左心室功能损害程度,并将其制成表格。左室功能下降与手术时间、旁路手术时间和主动脉夹持时间密切相关,其中以旁路手术时间最为重要。左室射血时间(Left ventricular ejection time, LVET)是术后即刻心功能最有用的参数,对5例术后早期死亡的患者具有预后价值。大多数患者中隔运动异常,但通常在2周内恢复正常。广泛手术后,主动脉小叶的运动模式也发生了变化。术后虽常发现心包积液,但不提示开心术后综合征,术后2个月内自然消失。
