Outline 1. Introduction: definitions; classification; recommendations for care 2. Special needs: arrhythmia; risk factors CAD; co-morbidity; changing interventional profile; prevention of complications
Spectrum of Disease GUCH Euro Heart Survey 4,110 patients 1998-2003 Engelfriet P et al, Euro Heart Journal 2005;26:2325
Classification of GUCH disease Simple Moderate Complexity Great Complexity Isolated valve Tetralogy of Fallot Cyanotic CHD Small shunts Coarctation Single ventricle (all variants) Repaired shunts (no complications) RVOT osbtruction or regurgitation (significant) Atrioventricular Septal Defects Ebstein s Non-isolated VSD Open shunts Simplified Bethesda Classification Warnes C et al, 2008: 118; e721 Valve atresia (all variants) Transposition Conduit repair Pulmonary Arterial HTN
Increase in Severe CHD Adults and Children 1985-2000 Marelli AJ et al, Circulation 2007; 115: 163
Changing landscape Patients with mild or moderate disease constitute the majority of patients followed even in specialized centers But the patient population which is growing at the fastest rate are the ones with severe disease which is going to alter what we see
ESC Guidelines Who should look after GUCH patients? Severe Disease GUCH care Moderate Disease Shared care Mild Disease Non GUCH centre care
Recommendations for Care General Cardiology General Cardiology GUCH Center ESC/AHA/ACC/CCS Guidelines
Increasing Numbers Equalization of Adults and Children Severe CHD 1985 to 2000 Marelli AJ et al, Circulation 2007; 115: 163
Health Services Utilization Hospitalization rates in Adults 22,096 adults 1996-2000 compared to the general population Mackie A.S et al, AJC 2007; 99:839
Changing landscape As a community, our goal is to keep up with the changing profile of the CHD population, to synchronize the care we deliver in order to ultimately improve its quality and make it more cost-effective

Complication Prevention Rushani D et al JACC 2012, 59(Suppl A): A199
Summary Most of what we see is moderate or mild disease Most cases should be referred to a GUCH centre at least once Atrial arrhythmias are common and have a different natural history in CHD compared to non CHD patients Pulmonary HTN is becoming increasingly interesting as a marker of poor outcome not only in those with PAH Risk factor control for CAD is very important especially in the young as shown in patients with CoA There are growing interventions especially for moderate disease Prevention of IE remains cornerstone and unsettled
