The aim of this study is to prospectively assess the early arrhythmia after transcatheter closure (TCC) of perimembranous ventricular septal defects (VSD) using the asymmetry and symmetry septal occluder device made in china. From June 2003 to January 2008, 53 patients with perimembranous ventricular septal defects underwent TCC using the device at a median age of 13.1 years (1.3 to 40.0 years) and median weight of 39.0 kg (11.0 to 81.0 kg). Electrocardiography (ECG) and ambulatory Holter monitoring was performed as pre and post-procedures. ECG and Holter analysis included heart rate (HR), PR interval, QRS duration, corrected qt interval (QTc), supraventricular ectopy (SVE), ventricular ectopy (VE), junctional tachycardia, ventricular tachycardia and conduction defects, including arterialventricular block and bundle branch block. It was revealed that, catheterization material and interventional treatment resulted to, surgical success, mean pulmonary artery pressure (mmHg) and lack of Qp/Qs diameter (cm), apart from the aortic distance (cm), occluder diameter (cm), the operation time (min), X-ray exposure time (min) and the two groups of comparisons that were found to be nonsignificant between each group. A significant increase in post-closure number of VE (P = 0.03) was noted. There is no significant difference before and after procedure in SVE change (P = 0.05), PR interval, QRS duration or QTc. Between the two groups × 2 test, the average rate (HR), PR in terval, QRS wave width, calibration QT interphase QTc (atrioventricular junction area), (AVE), ventricular premature beat (VE), border tachycardia (SNRT NPJT) and NPVT ventricular tachycardia (paroxysmal atrioventricular), showed no significant difference in conduction block. However, the independent variables and ventricular premature beat the linear regression analysis; on the other hand, the increase of age and early number ventricular premature beat (P = 0.02), weight, gender, chamber of occluder diameter and ventricular size or number of borders changes at an earlier stage. After transcathete closure, the patient significantly increased the number of ventricular premature beat, accelerated border and ventricular arrhythmia independently, but we should prevent postoperative highly atrioventricular block occurrence and strengthen the postoperative patients ECG monitoring. © 2010 Academic Journals.
