Analysis of morpho-functional parameters of the subepicardial veins of the human heart in the intermediate fetal period

Abstract

The purpose of research was the analysis of morpho-functional parameters of the subepicardial veins of the human heart in intermediate fetal period (13-24 weeks of pregnancy) . The research has carried out in 64 normal heart speciments of the human fetuses of gestation weeks 13-24 . The methods of macroscopic and microscopic preparation , morphometry , digital photography , variation statistics were used . In the issue the parameters and levels of formation of tributaries of the coronary sinus were studied . Obtained results maybe used in fetal cardiac surgery , with the purpose of more effective usefulness of subepicardial veins of the fetal heart in such manipulations as an occlusive retrograde venography or hyperemic venous return angiography , radiofrequency catheter ablation of additional conductive ways of heart , cardiac resynchronization therapy (CRT), correction of congenital heart diseases .
