Normally, the pressure gradient is very small (a few mmHg); however, the pressure gradient can become quite high during severe … 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.
