Structure and function of the canine ventricular myocardium (Canis lupus familiaris): Ventricular myocardial band
Introduction: currently, there are new diagnostic tools and therapies for heart disease, but with no serious scientific consensus on the questions about the normal structure and function of the heart. Helical ventricular myocardial band of Torrent-Guasp is the revolutionary new concept in understand...
