WebbThe aortic valve is a one-way valve (doorway) between the heart and the aorta. Normally, the aortic valve has three small flaps or leaflets that open widely and close tightly to regulate blood flow. The valve allows blood to flow from the left ventricle (pumping chamber) to the aorta and prevents blood from flowing backward. WebbThe mitral valve allows blood to flow from the left atrium to the left ventricle in the heart. Mitral valve prolapse (MVP) is the bulging (prolapse) of 1 or both of the mitral valve flaps (leaflets) into the left atrium when the heart contracts. When the flaps don't close properly, blood leaks backward. This is called regurgitation.
