Pressure Gradients Across a Stenotic Heart Valve
Pressure Gradients Across a Stenotic Heart ValveTo assess the seriousness of a heart valve stenosis, it would be helpful to know the area of the stenosed valve when open, or how much of the valve opening is being blocked by the stenosis. Gorlin and Gorlin (1951) developed an equation to empirically predict valve area based on the pressure drop across the valve and the flow rate through the valve. The published equations that were useful for the prediction of area in mitral and aortic valves are still used in cardiology today (Cannon et al.1985).Harris and Robiolio (1999) write, "Although the 'gold standard' for assessment of the severity of mitral stenosis has long been the Gorlin formula derived from data obtained from cardiac catheterizati…
