THE MOVEMENT OF AORTIC AND PULMONARY VALVES STUDIED POST MORTEM BY COLOUR CINEMATOGRAPHY

Abstract
A method of studying the action of human pulmonary and aortic valves obtained shortly after death is descr. The purpose was to study the action of human heart valves in an artificial system, the flow through which was designed to resemble that in the living heart. The heart valves in motion are recorded in various phases of systole and of diastole.
