Abstract:
Objective To study the prevalence and risk factors of heart conduct block after transcatheter closure of ventricular septal defect (VSD)surgery. Methods A total of 1 069 cases underwent transcatheter closure VSD were retrospectively analyzed. The risk factors were assessed by multivariable logistical analysis. Results The median follow-up time was 2.2 (1 to 4.16) years. The early post-procedure heart conduct block was 20.5 %(219 cases), and 35 cases underwent severe conduct block (3.3%). During the follow-up, there were 43 late onset heart conduct block (4.0%), including 4 (0.4%) complete atrioventricular block. Multivariable logistic analysis showed that implanted of asymmetrical occluder from foreign company was the risks factors for early onset severe conduct block, with longer procedure time. Placement of thin-waist-big-side occluder were risk factor for the late onset conduct block. Conclusions Heart conduct block after transcatheter closure VSD is common , light and recovery. The late onset severe conduct block is minor. Symmetrical occluder should be chosen in transcatheter closure VSD if possible.
