Chordae Tendineae Architecture in the Papillary Muscle Insertion Arquitectura De Las Cuerdas Tendinosas En La Unión Con El Músculo Papilar

As a requirement for the pumping function, the heart must have a determined arrangement of the ventricular muscle fibers (Ingels, 1997). The papillary muscle and the trabeculae carneae are formed by the ventricular fibers originated from the cardiac muscle layers which project into the ventricular left cavity. Those structures are in direct contact with blood flow and actuate determining the adequate blood course, participating directly in the myocardium contractile function.
