Objective To discuss the individualized choice of the type of the occulder is the key prevalence and prevention therapy of conduction blockade after interventional occlusion of perimembranous ventricular septal defect(PMVSD). Methods 243VSD patients were acceppted the interventional occlusion successfully. The distance from upper margin of the defects to the ring of the right aortic valve(DDRAV), diameter of the VSD were measured by ultrasonicm before the interventional occlusion. Conduction Blockade after interventional occlusure treatment was analyzed retrospectively in all 243 VSD patients. Results Relative to the ring of the right aortic valve(DDRAV) and the diameter of the VSD, The type of the occulder plays important roles in the development of conduction blockade after interventional occlusion(P =0.001). Conclusion The type of the occulder plays important roles in the development of conduction blockade after interventional occlusion. Most of the conduction blockade can resume after timely therapy.
