Your heart contains four valves that open and close to control the flow of blood through it. A heart attack or enlargement of the heart can cause the leaflets of the valve to spread apart, leading to mitral regurgitation. [citation needed] The truncus arteriosus is originally a single outflow tract from the embryonic heart that will later split to become the ascending aorta and pulmonary trunk. Heart attack.
