Measures for decreasing the early mortality after atrial septal defect and ventricular septal defect with unsuccessful interventional treatment / 中国医师进修杂志

ABSTRACT

Objective To probe the effective measures for decreasing the early mortality after unsuccessful interventional treatment for atrial septal defect(ASD)and ventricular septal defect(VSD).Methods A total of 16 patients who underwent surgical treatment of unsuccessful interventional treatment for ASD and VSD from January 2000 to December 2007 were included in this retrospective analysis.Surgical indication was the occluder abscission(7 cases),cardiac perforation(3 eases),the third degree atrioventricular conduction block(3 cases),valvular regurgitation(2 cases,1 case accompanied with the third degreeatrioventricular conduction block),residual shunt(1 case),unsuecesflful interventional treatment(1 case).An of 16 cases underwent surgical treatment including removal of the displaced occluder and/or the congenital heart disease repaired on cardiopulmonary bypass.After surgical treatment.all patients were transferred into ICU for further supervision and treatment.Results There Was no hospital mortality.Twelve ASD cases were performed after the interventional treatment,which included 5 cases with central ASD and 7 CaseS with inferior sinus venous ASD.Coincidental rate between operating exploration and preoperative diagnosis was 41.7%(5/12).Misdiagnostic rate between them was 58.3%(7/12).The diameter of ASD (31.0 ±1.0)mm by operating exploration after interventional therapy of ASD obviously increased compared with that(26.0±2.3)mm before preoperative diagnosis(P<0.05).The diameter of VSD(5.0±0.8)mm by operating exploration after intervenfional therapy of VSD obviously increased compared with that(4.0±0.3)mm before operative diagnosis(P>0.05).,The third degree atrioventricular conduction block(3 cases)restored sinus rhythm after operation.Procedure was successful in all patients.Conclusion It is necessary to monitor severe complications of unsuccessful interventional treatment for ASD and VSD to assure the successes of the operations.
