Surgical Repair of Atrial Septal Defect in Adult Patients / 日本心臓血管外科学会雑誌

ABSTRACT

Fifty-five adult patients with atrial septal defect (ASD) were surgically treated. In the preoperative study, 6 patients showed high pulmonary artery systolic pressure (>50mmHg). However, there was no linear relation between PAP and age, nor between <i>Q</i>_p/<i>Q</i>_s and PAP. As for the additional surgical procedures, MVR (1), MAP (1), TAP (3), OPC (2) were carried out with ASD closure in 7 patients. Post-operative evaluation with echocardiography revealed increase in the left ventricular chamber size, decrease in the severity of tricuspid regurgitation and same grade mitral regurgitation compaired with pre-operative level. From these data, the prediction of the atrioventricular valve regurgitation after ASD closure seemed to be difficult just from the preoperative evaluation, Transesophageal echocardiography was useful for the evaluation of residual atrioventricular valve regurgitation during operation in the cases of ASD with over II grade regurgitation preoperatively.
