Abstract:
Objective To evaluate the feasibi1ity and efficacy of transcatheter closure of perimembranous and muscular ventricular septal defects (VSD) using the new Amplatzer membranous and muscular VSD occluder and observe the effect of membranous VSD occluding procedure on atrioventricular(AV) conductive system.Methods Twelve patients (7 males,5 females) with perimembranous VSD and two patients (1 male,1 female) with muscular VSD underwent an catheter closure using the new Amplatzer membranous and muscular VSD occluder.All patients who were eligible for device closure by means of cardiac Doppler echocardiography were routinely measured the parameters of blood dynamics before catheter closure. Artery-venous track was set up under the X-ray fluoroscopy,transesophageal (TEE) or transthoracic echocardiography (TTE) guidance. Devices were released in the right ventricular side.Twelve patients with perimembranous VSD underwent the cardiac electrophysiologic examination,including atrioventricular conductive time (AV interval) and atrioventricular nodal refractory time,before and after catheter closure.A11 patients were followed up at 2 weeks,1 month,3 months and 6 months after the procedures.Results The devices were deployed successfully in 14 patients.There was complete closure in 12 patients immediately,and tiny (
