[Transfer of cardiac catheterisation from a paediatric to an adult cardiological centre: results at 3 years].

The advances of surgical and interventional treatment of congenital heart diseases have allowed a large number of patients with congenital heart disease to reach adult age. This population involves almost 0.3/1000 of total population in West Europe and North America and can be estimated around 200000 patients in France. Patients with operated Tetralogy of Fallot, benign forms of pulmonary atresia with ventricular septal defect, simple or complex transposition of the great arteries usually survive beyond childhood. These patients can need repeated interventions to treat lesions of native or reconstructed pulmonary arteries and/or aortic arch, to occlude residual shunts, to treat pulmonary incompetence. More complex heart diseases such as single ventricle, rarely allow survival until the adult age. The majority of these patients undergo heart transplant, often made difficult by multiple cardiac surgeries, anomalies of pulmonary arteries, chronic cyanosis, aorto-pulmonary shunts. Patients with relatively simple or complex congenital heart diseases need to be followed-up in specialized units, like those created more than twenty years ago in the United States, Canada, and United Kingdom. Interventional cardiac catheterisation play a major role in the management of this population. The results of 3 years of activity in a new centre treating GUCH patients are illustrated.
