    Abstract:
    Surgery for congenital heart defects started 50 years ago with "closed" procedures, and open heart surgery is in its forth decade. Thus, long-term results are now available. Although a majority of patients lead normal lives, problems do exist. Hemodynamic anomalies can be related to residual lesions or to persistent systemic hypertension (after coarctation repair) or pulmonary hypertension (after late repair of left to right shunt lesions). Right or left ventricular dysfunction may be observed, due to longstanding overload, hypoxia or to the open heart procedure itself. Rhythm disturbances have a tendency to increase with the passage of time after surgery. After ventricular surgery (repair of ventricular septal defect and tetralogy of Fallot), conduction defects and ventricular arrhythmias are prevalent. They may lead to late sudden death. After atrial surgery, sinus node dysfunction and atrial arrhythmias are observed. Problems related to growth of the patient exist essentially in cases where foreign material (conduits, prostheses) have been implanted. Many patients, with definitive repair or palliative operation, have become adults. This is a new challenge for the adult cardiologist, and it is a duty of the pediatric cardiologist to hand over his knowledge of this pathology.
