The SI unit for pressure is the pascal (Pa), equal to one newton per square metre (N/m 2 or kgÂ·m â1 Â·s â2). This name for the unit was added in 1971; before that, pressure in SI was expressed simply in newtons per square metre.
A leaking mitral valve allows blood to flow in two directions during the contraction. Some blood flows from the ventricle through the aortic valve â as it should â and some blood flows back into the atrium. A leaking (or regurgitant) aortic valve allows blood to flow in two directions.
Mitral valve regurgitation cause anemia - Could mitral valve regurgitation cause anemia? Unlikely. If one has mixed mitral valve disease with a heavily calcified mitral valve that is both stenotic and regurgitant, one could imagine marked turbulance of the blood flow across the mitral valve with destruction of rbc's however, this is very unlikely.
