Human coronary sinus - from Galen to modern times.

Based on the review of the current literature and our own experiences we reviewed the literature paying most attention to human venous coronary system with special respect to coronary sinus - the largest vein of the heart. Many details still remain obscure, although most of modern procedures require deep anatomical knowledge on cardiac veins. Many of developmental remarks are still not clear, regarded to development of the vessels of the heart in association with origin of heart conductive system.
