Morphological Study of Small Cardiac Vein, Right Marginal Vein, Posterior Vein of the Left Ventricle, Left Marginal Vein, Oblique Vein of Marshall, and Anterior Cardiac Veins in Human Hearts of Western Region of U.P – Clinical Implication

Introduction: Cardiac venous system is an important system for various cardiac interventional procedures such as cardiac catheterization. Various veins like right marginal vein, small cardiac vein (SCV), posterior vein of the left ventricle, left marginal vein, oblique vein of Marshall drain into coronary sinus. While anterior cardiac veins drain right ventricular wall directly into right atrium. Materials and Methods: An observational cross-sectional study was conducted on thirty cadaveric hearts during a 2-year period in Shri Ram Murti Smarak Institute of Medical Sciences, Bareilly, Anatomy Department. The length, diameter of SCV, left marginal vein, posterior vein of the left ventricle, right marginal vein, and oblique vein of Marshall were taken. Results: The study reveals the length of SCV as 28.12 ± 22.87 mm. The length of right marginal vein and posterior vein of the left ventricle is having a significant correlation with age. The length of oblique vein of Marshall is lower in males as compared to females. A number of ACVs were significantly related to weight of cadaver in males. Conclusions: The present study provides data of cardiac veins for various cardiac interventional procedures.
