Endovascular intervention in the treatment of congenital heart disease in adults.

Over the last years, endovascular intervention have become an important part of treatment in patients with congenital heart disease particularly for residual defects after surgery done in infancy. These transcatheter procedures can be described as dilatation of stenotic sites (angioplasty, endovascular stenting and valvuloplasty) or as a closure of anomalous openings (device closure defects and vascular embolisation). Balloon valvuloplasty, without or with stent, is the procedure of choice in adults with pulmonary valve stenosis, pulmonary arteries stenosis, bicuspid aortic valve stenosis without calcification, aortic re-coarctation. Treatment of native aortic coarctation is still under debate. Devices for closing atrial and ventricular septal defects or patent ductus arteriosus have been developed and are now widely used. Transcatheter, plug or coil occlusion is nowadays the goal treatment in a wide range of arterial and venous vascular connections. This review describes the current role of each major catheter-directed therapy in the treatment of congenital heart disease in adults.
