Abstract

Mitral valve resistance is defined as the ratio of the atrio-ventricular pressure gradient to the volumetric flow across the valve in diastole. The mitral valve inertiance is defined as the product of the blood density and the volumetric flow rate. These physiologic parameters have been usually determined by invasive methods such as cardiac catheterization. We show that quantitative determination of the mitral resistance to inertiance ratio can be accomplished by solution of the 'inverse problem' of diastole, when the clinical transmitral Doppler tracing is analyzed using the parametrized diastolic filling (PDF) formalism.
