Right heart function assessment with real-time three-dimensional echocardiography before and after atrial septal defect surgery
Objective:To study the clinical value of right heart function assessment with real-time three-dimensional echocardiography before and after atrial septal defect surgery. Methods:Patients with atrial septal defect who received transcatheter closure in our hospital were selected for study and divided into non-pulmonary hypertension group and pulmonary hypertension group according to pulmonary artery systolic pressure (PASP), real-time three-dimensional echocardiography was conducted before and after operation, and right ventricular end-diastolic volume (RVEDV), right ventricular end-systolic volume (RVESV), right ventricular stroke volume (RVSV), right ventricular ejection fraction (RVEF) and right ventricular cardiac output (RVCO) were calculated;serum was collected, and brain natriuretic peptide (BNP), atrial natriuretic peptide (ANP), angiotensin I (AngI), angiotensin II (AngII) and endothelin (ET) contents were detected. Results:After operation, RVEDV, RVESV, RVSV, RVEF and RVCO as well as serum BNP, ANP, AngI, AngII and ET contents of both groups were lower than those before treatment;RVEDV, RVESV, RVSV, RVEF and RVCO were positively correlated with contents of BNP, ANP, AngI, AngII and ET. Conclusions:Using real-time three-dimensional echocardiography before and after atrial septal defect surgery can accurately assess right heart function, and it has good correlation with right heart volume load and pulmonary circulation blood flow.
