Mitral Valve Resistance as a Hemodynamic Indicator in Mitral Stenosis Reinaldo W. Beyer, MD, Alfonso Olmos, MD, Ruben F. Bermtidez, MD, and H. Elizabeth Nell, MD
Variability of the valve area calculated by the Gorlin fonnuia has beon noted in bioprosthetic and aortic valves, but few data are available for native stenotic mitral vatves. Valve resistance has been proposed as an alternattve hemodynamic indicator; however, its value in mitraf stenods has not been assessed. Thirty-four patients had simultaneous recordings of teft atrial and ventricular pressures, 26 after percutaneous batioon mitral dilatation (PBMD). Patients with shunt or mitral regurgitation were excluded. Mitral vaive resistance correlated exponentially with Got-tin mitral area (y = 133*[area]-1*s; p
