Interventional therapy for congenital heart disease (CHD)was introduced in the 1960s following animal experiments and clinical studies using transluminal technique. However,it was not widely accepted in clinical applications until the 1990s because of the limitations of interventional devices and catheter technique. Interventional therapy is now well developed as a result of successful animal studies and clinical trials. It has a higher success rate than that of surgery in some CHD cases such as patent ductus arteriosus (PDA), pulmonary valve stenosis (PS), atrial septial defect (ASD) and coarctation of the aorta (CoA), and it may palliate some CHDs by atrial septostomy and interventional embolization of the pulmonary arteriovenous fistula.
