Anatomy of the Ventricular Coronary Arteries in the Dog

The ventricular coronary arterial system of the dog displays preponderance of the left in 100 per cent of the animals studied. The single most important source of blood supply is the left circumflex artery, which supplies not only most of the left ventricle, but also significant portions of the right ventricle. Details of the septal branch are described. Morphological implications concerning death or survival in experimental coronary occlusive procedures are discussed. A simple nomenclature is offered.
