Discordant aortic valve measurements

A fictional adult with exertional breathlessness has a small calculated aortic valve area and a lower-than-expected mean transvalvular gradient. The ventricle has impaired systolic function and a reduced measured stroke volume. The referring team has not yet confirmed the left ventricular outflow tract measurement, Doppler alignment or consistency of the stroke-volume calculation. One clinician proposes that the low gradient excludes important stenosis, while another says the small area alone proves that the valve must immediately be replaced by one specific technique. The Heart Team instead requests verification of the measurements, integrated assessment of flow and appropriate additional imaging. Comorbid conditions and the patient priorities also remain relevant to the eventual treatment decision.
