ABSTRACT
Objective:To study the application value of echocardiography in transcatheter atrial septal defect closure.Methods: Chosen 2012-2014 years our hospital 68 patients with transcatheter atrial septum closure, using the thoracic echocardiography in patients with transcatheter atrial septum closure under general anesthesia guided and cardiac function monitoring.Results: All 68 patients with atrial septal defects under the guidance and monitoring via thoracic echocardiography defect plugging successfully completed, the average operation time was (23.8±4.7)min; the average hospitalization day was (5.2±1.3)day. Three days, 3 months after operation, right ventricular end-diastolic diameters were narrowing (t=11.232,t=16.589;P<0.05); The right atrium insides were narrowing (t=10.573,t=14.793;P<0.05); left ventricular end-diastolic diameters, were increasing (t=9.378,t=12.245;P<0.05); pulmonary artery diameters were narrowing (t=10.026,t=13.873;P<0.05).Conclusion:Echocardiography can do the entire guide, cardiac function monitoring in transcatheter atrial septal defect closure, postoperative follow-up and curative effect evaluation.
