WebMar 3, 2013 · Valve Dimensions / Measurements. Normal mitral valve area is 4-6 cm2, symptoms usually commence at 2 cm2 or less. “Critical stenosis” is defined as 1 cm2 or less, and is usually symptomatic at rest. 1-1.5 cm2 usually causes mild symptoms on exertion, and 1.5 cm2 -2.0 cm2 is usually asymptomatic unless significantly stressed. WebJun 30, 2024 · For this reason, the HR at which gradients are measured should always be reported. Although the PHT may provide a clue to the presence of mitral prosthetic obstruction, it is not useful for calculating the EOA because this method has only been validated for native mitral valve stenosis. simotion d software download https://mrhaccounts.com
