QUOTE: "what does aorta insufficiency mean? does it relate to mitral valve prolapse? what is the diference between mitral valve prolaps and regurgitation? thank you"
>>>>Aorta valve is the valve that is a one way pass of blood from the left vetricle (pumping chamber) into circulation. Insufficiency means some of the blood back flows into the left ventricle and not into circulation.
Mitral valve is the one way pass of blood from the left atrium (upper heart chamber that receives blood from the lungs) into the left ventrical (lower chamber). The valve has leaflets that should tightly close the mitral valve and prevent regurgitation (backflow of blood). There is leaflet prolapse that indicates it is the leaflet(s) that are causing the regurgitation.
