Small cardiac vein
Citation, DOI & article data
The small cardiac vein is a vein of the heart which accompanies the acute marginal artery from the RCA. It courses in the right posterior atrioventricular groove and drains into the coronary sinus close to its termination but may drain directly into the right atrium. It drains the right ventricle. It may receive one or several of the anterior cardiac veins but these usually drain the anterior surface of the right ventricle directly into the right atrium.
