[Interventional catheterization in pediatric cardiology: tools and indications].

During the last decade, a remarkable number of transcatheter methods were developed. These developments include balloon dilatation to treat vascular or valvular obstructive lesions, intravascular stents to manage obstructive lesions that cannot be satisfactorily balloon-dilated, transcatheter closure of atrial septal defects, patent ductus arteriosus, and ventricular septal defect. More recently, pulmonary valve replacement has become possible through a percutaneous technique enlarging a bit more the field of interventional cardiology.
