Abstract
Objective To evaluate the ability of transthoracic Doppler echocardiography in assessing atrial secundum septal defect before and post-operation.Methods Retrospective reviewed cased from January 2010 to January 2013 who ad-mitted with secundum atrial septal defect and successfully received implemented interventional surgery ( n =20 ) .Analyzed the relationship between preoperative transthoracic echocardiography measured the maximum diameter of the defect and the catheter based measurement of the balloon occluder model .Transthoracic Doppler echocardiography were applied at 3 d after operation and three months after operation , to review the position and shape of the occluder , the size and function of the right atrium and right ventricle , as well as changes in the pulmonary artery .Results Preoperative atrial septal defect size measured by transthoracic echocardiography was 7-40 (24.6 ±8.2) mm, intraoperative determination the size and then success release of the balloon occluder , the measured value was 8-40 (24.8 ±8.5) mm, Spearman correlation analysis showed that there was a significant correlation between the two measurement ( r =0.930, P <0.01).After 3 d and 3 months of operation, transthoracic color Doppler echocardiography examination showed normal morphology and position of occluder , the right atrium diameter and anterior to posterior diameter of the right ventricle , pulmonary artery diameter , right ventricular end-diastolic vol-ume (RVEDV), right ventricular end-systolic volume ( RVESV), right ventricular stroke volume ( RVSV) were improved significantly compared with the before operation , and the difference was statistically significant ( P <0.01).Compared with the before operation , 3 d and 3 months after operation , right atrial diameter from top to bottom , anterior to posterior diameter of right ventricular , pulmonary artery diameter , right ventricular systolic diameter , right ventricular end-diastolic diameter and right ventricular stroke volume was significantly reduced ( P <0.01), after three months improved more significantly ( P <0.05).Conclusion Transthoracic Doppler echocardiography is safe , effective and easy way to guide and evaluate secundum atrial septal defect occlusion .关键词
