When is stress echocardiography in mitral stenosis useful?

2 scenarios: 1) stress testing objectively quantifies the person's exercise capacity, to determine if they are symptomatic from the valve, which affects surgery consideration. 2) sometimes the resting echo suggests less severe stenosis than the person's symptoms. Stress echo can confirm severe stenosis if the gradient across the valve, or pulmonary pressure, increases significantly.

To assess severity : Stress echocardiography is indicated in asymptomatic patients with echocardiographically severe lesions as well as for patients with symptoms disproportionate to resting doppler hemodynamics.
