摘要
以多普勒超声心动图技术评价42例室间隔缺损修补途径与术后早期心功能变化的关系。结果表明,经右室切口修补组术后早期右室收缩功能,和左室舒张及收缩功能受损程度明显加重,且恢复延迟。因此采用经右心房或肺动脉切口修补,有助于减少术后心力衰竭的发生。
The relationship of different repairing approaches and their early postoperative ventricular function were investigated in 42 cases of ventricular septum defect by Doppler echocardiography. In the group (n=22) repaired by ventricul-otomy, early postoperative EPEP/RVET was twice as long as in that group (n= 20) repaired by right atrial or main pulmonary artery and also recovered significantly slower. Diastolic filling (E/A) and contractibility (LPEP/LVET) of the left ventricle were significantly correlated with EPEP/EVET. These results, suggest a nonventricular approach to be beneficial in lessening early postoperative ventricular dysfunction.
