The goal of this learn is to offer accomplished morphological info, just about all of it's new, about the venous drainage of the myocardium through the coronary sinus and its similar veins. this data is of serious importance, no longer least for the sucessful coronary sinus catheterization and reperfusion of so much, or unmarried, cardiac veins.The writer offers the 3 central cardiac venous platforms, the higher (major) cardiac venous, the smaller (minor) cardiac venous approach, and the compound venous procedure. The paintings concludes with an evaluate of the numerous anatomical peculiarities and and stumbling blocks in regards to the catheterization of the coronary sinus and the reperfusion of (selected) cardiac veins.

In some cases the SCV has been found to drain the RMV and a few of the ACVs. In two corrosion specimens, there was a duplication of the SCV: the two vessels fused at 25 mm along their length, forming a (terminal anastomosing) venous loop.

In one case the vein emptied into the terminal CS between the leaflets of the ostial valve. The opening of the vein could not exactly be determined in cases where no valve of the CS existed (8%).
