Abstract

Ultrastructural signs of compensatory hypertrophy (channels of granular endoplasmatic reticulum well developed Golgi complex, dilatation of T-system channels, alterations of the myofibrillar structure, appearance of non-parallel myofibrills, groups of small mitochondria, numerous intercalated disci) were found in the cardiomyocytes of the right ventricle effluent region of the adult (18-40 years) and young (6-12 years) patients with tetralogy of Fallot. Some cells showed degenerative changes-a transition of the hypertrophic cells in the stage of decompensation.
