• Changes in loading conditions and contractility during a patient's life may lead to alterations in the severity of lesions, good or poor ventricular contractile reserve, altered volume-dependent compliance of heart chambers, and ventricular arterial coupling. [...]there may be a need for stress testing and imaging in this setting. A [= or >, slanted]18 mm Hg increase in mean transaortic pressure gradient predicts a higher risk of cardiac events and has been shown to provide incremental prognostic information over clinical, resting Doppler echocardiographic and exercise testing. 8 Exertional symptoms are better predicted by valve compliance during dobutamine stress than by resting Doppler parameters, but the clinical significance of valve compliance requires further studies. 4 Despite the recommendations to perform exercise testing in patients with asymptomatic severe aortic stenosis and the valuable information obtainable by the test, the recent Euro Heart Survey on valvular heart disease revealed that an exercise test was performed in only 5.7% of patients in this setting. 1 Low flow/low gradient aortic stenosis Who needs stress testing?
