Clinical application of intraoperative epicardial echocardiography in cardiac valve surgery / 中华超声影像学杂志

ABSTRACT

Objective To evaluate the clinical value of epicardial echocardiographic examination in cardiac valve surgery.Methods Epicardial echocardiography were performed in 46 patients undergoing valvular plasty or valvular replacement surgery to estimate the function of valve and left ventricle and residual shunt during cardiac surgery.Results Twelve cases of 46(26.1％)showed abnormality during cardiac surgery.Two cases of 15 patients performed valvuloplasty were changed to valvular replacement because of remarkable regurgitation of native valves.There was 1 case of periprosthetic leakage,3 cases of left atrial appendage thrombus,1 case of patent foramen ovale and 5 cases of low ejection of left ventricle in all 31 cases of valvular replacement.Conclusions Epicardial echocardiograpyc examination is an effective examination in cardiac valve surgery with clearly image,simplicity operation and promptness.
