Blocked vs Leaking: Stenosis means the valve does not open enough and restricts the flow of blood thru the valve. Regugitation means the valve leaks when closed and allows blood to flow in reverese. Both cause the hear to have to work harder. Mitral regurge is much more common than stenosis in industrialized nations because antibiotics used to treat strep infections have reduced rheumatic fever rates.
