Veins of the heart Trace the veins of the heart to determine which vessel drains each area of the heart. Coronary sinus Great cardiac vein Middle cardiac vein Posterior vein of the left ventricle Small cardiac vein Accompanies the anterior interventricular artery and drains a majority of the left side of the heart. Accompanies the posterior interventricular artery and drains the posterior wall of both ventricles. Accompanies the right coronary artery and drains the inferior and lateral wall of the right ventricle. Collects blood from the surface of the heart and drains into the right atrium. Drains the posterior aspect of the left ventricle.
