The care of complex congenital heart defect (CHD) patients should be contin
uous through life. Medium- and high-risk patients should be seen in special
facilities for grown-up congenital heart (GUCH) patients, and followed for
life. CHD in the adult is different than CHD in the child. Transitional pr
ograms should be available to prepare the adolescent patient to take charge
of his/her own health. The patient should be transferred smoothly from ped
iatric to adult care. GUCH care should be regionally anchored in special fa
cilities (groups or sometimes individuals) willing to make a commitment to
their care. Ideally, pediatric and adult cardiologists will collaborate. GU
CH care should be multidisciplinary wherever possible - and certainly in su
praregional centers. Surgery, diagnostic catheterization, interventional ca
th procedures, EP management, and even MRI should be done in selected cente
rs with high quality services for all cases other than the most simple lesi
ons. Care should be available at all times. Surgeons who operate on childre
n with similar conditions should perform the most GUCH surgery. GUCH surger
y should be performed in centers with adequate institutional and individual
surgeon's volumes. In determining which surgeons and units have adequate v
olumes, both pediatric and adult volumes should be combined.
