[Interventional catheterization in children].

In children, interventional catheterization is performed to treat congenital heart diseases: balloon atrial septostomy; balloon valvotomy for valvar pulmonary stenosis, valvar aortic stenosis, valvar mitral stenosis; balloon angioplasty for venous or arterial stenosis. Transcatheter vascular occlusion can be accomplished using a wide range of devices: transcatheter patent ductus arteriosus closure, embolisation of arteriovenous malformations, systemic-pulmonary collaterals and other extracardiac shunts. Intracardiac or intravascular catheters can be removed.
