[Surgical treatment of congenital abnormalities of the right heart].

The surgical treatment of complex congenital malformations of the right heart is described and discussed with regard to the following heart diseases: tetralogy of Fallot (FT), transposition of the great arteries (TGA), tricuspid atresia (TA), single ventricle (SV). The results of the patient material of Goettingen were focused on the right ventricular function. With reference of the FT-correction a residue pulmonary stenosis is considered to be better tolerated than a residual pulmonary insufficiency. The long-term results (observation time from 4 to 17,5 years) proved that the right ventricle (RV)-function can adapt itself to pressure load. Adequate growth to the hypoplastic right ventricle is documented due to right ventricular volume load after operative repair. The Fontan procedure for TA and SV has revealed that the inactivation of the right ventricular pumpunction has not resulted in negative effect on the function of the systemic ventricle, patients clinical conditions and exercise testing have improved.
