As demonstrates the light optic and electron microscopic investigation of the myocardium, after a local lesion of the cardiac atrium and ventricle in mature pigeons, restoration of the myocardial wall continuity occurs at the expense of the connective tissue scar. In cardiomyocytes of the zone adjoining the traumatized area, where the lesion is minimal, recovery of the myofibrillar apparatus takes place by means of restoration of the partly injured myofibrils. It is not impossible that a part of myofibrils are formed anew. These myofibrils, however, are observed to destroy with time.
