Abstract:
Objective To investigate the feasibility and clinical effectiveness of interventional ventricular septal defect(VSD) occlusion using asymmetric occluders in patients whose VSD are adjacent to aortic valves.Methods One hundred and fifty-two patients from our hospital whose VSD were occluded with asymmetric occluders were examined by echocardiography.Dimensions,shapes and shunts of VSD,structures around defects were observed and aortic valve prolapse(AVP) degrees were accessed before the interventions.The patients were followed up periodically after the procedures.The longest follow-up was 6 years.Results Sizes of VSD measured from left ventricular side were larger than those measured from right ventricular side.Twenty-seven cases with VSD had mild AVP.Right sides of defects had adhesions with variable morphological patterns in 85% patients with perimembranous VSD.After occlusion,there were 7 cases showed residual shunt,2 cases with the third degree atrio-ventricular blockages,3 cases appeared aortic-valve regurgitations (AR) and 1 case with slightly increased AR.Conclusions Immediate and medium-term effects of interventional occlusion with asymmetric occluders were satisfactory in the patients with VSD and mild AVP whose aortic valve margin were insufficient to symmetric occluders.Surgical operation should be preferred to patients with VSD and moderate to severe AVP and to very young children.Pre-closure echocardiographic evaluation is critical to the success of interventional closure with asymmetric occluder and the long-term out coming.
