title: [State of the blood microcirculatory vessels of the heart in congenital defects].
abstract: The condition of hemomicrocirculation vessels in congenital heart disease was studied by silver nitrate impregnation of thick sections. Adaptive and pathological alterations in the microcirculatory bed of the heart in various developmental anomalies are described. The role of adaptive alterations of terminal vessels in an abnormal heart in the blood supply to hypertrophic myocardium is shown. It is suggested that pathological alterations in the microcirculatory bed of an abnormally for-med heart are associated with its functional over loading and weakening of coronary circulation. It is concluded that degenerative, focal destructive, and sclerotic processes in hypertrophic myocardium in congenital heart disease may depend on disturbances of microcirculation in the heart.
