Summary
The purpose of this study is to evaluate blood clots after Percutaneous ASD Closure in
different age, sexuality and defective diameter; evaluating the relationship of blood
clotting with Occluder, injury of intima and inflammation;comparation of the effect and
safety between different anticoagulation after Percutaneous ASD Repair; explore propose an
optimal anticoagulation plan.
Clinical Details
Official title: A Multicentre, Randomized Controlled Study of Blood Clotting After Transcatheter Atrial Septal Defect Closure
Study design: Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Open Label, Primary Purpose: Prevention
Primary outcome: A Multicentre, Randomized Controlled Study of Blood Clotting After Percutaneous Atrial Septal Defect closure
Detailed description:
Atrial septal defect (ASD) is a common clinical congenital heart disease. It is estimated
that the congenital heart disease increase in children by about 15 million annual in China
, of which ASD accounted for 10% to 15%. Secundum ASD is the most common clinical type of
ASD, of which about 70% is suited to tanscatheter close. With the cardiac catheterization
advancing and the devices developing in recent years ,the method has gradually replaced
open-chest surgical repair to the person with Secundum ASD. At present, the most widely used
device is Amplatzer occluder. With the wide ues of the occlur,there has gradually emerged
occluder thrombosis after closure. there are much different methods to antiplatelet and
anticoagulation,not only in China but also in the world. so we perfom the study to evaluating
the blood clotting after Percutaneous ASD Closure in different age, sexuality and defective
diameter; evaluating the relationship of blood clotting with Occluder, injury of intima and
inflammation;comparation of the effect and safety between different anticoagulation after
Percutaneous ASD Repair; explore propose an optimal anticoagulation plan.
