Morphology and Morphometry of Venous Drainage System of Heart: A Retrospective Cadaveric Study
Journal Title: International Journal of Current Research and Review - Year 2018, Vol 10, Issue 10
Abstract
Introduction: In recent times the veins of the heart have gained importance as a treatment modality for the ischaemic myocardium and carry great importance in cardiac surgery. This treatment is possible because of the presence of intramyocardial collateral venous circulation Anatomic mapping of the cardiac veins is important to guide transvenous procedures such as biventricular pacing. A detailed knowledge of cardiac venous anatomy is necessary for successful catheterization of the coronary sinus and cardiac veins. Material & Methods: The dissection of the cardiac veins was carried out on 30 preparations of formalin fixed hearts obtained from cadavers during routine undergraduate teaching. About 10 ml of CAB solution (Cellulose Acetate Butyrite crystals in acetone) was injected into the coronary sinus. The specimens were left overnight and then placed into the 5% formalin solution. The specimen was dissected to expose coronary sinus with its tributaries. Various parameters including length, diameter of coronary sinus and its tributaries and presence of muscle bridges were noted. Observations: CS was present in all 30 (100%) cases. The mean diameter of CS was calculated as 8.87±1.48mm. The great cardiac vein (GCV) normally drains the left atrium and both ventricles. This pattern was seen in 20 cases (66.6%). Arteriovenous anastomosis between GCV and the right coronary artery and anterior interventricular branch of left coronary artery were observed in 13.3% cases respectively. The present findings are discussed in light of available literature.
