Value of multiplane transesophageal echocardiography in determining aortic valve area in aortic stenosis.
Aortic valve area determination by transesophageal planimetry and by the continuity equation was compared with hemodynamic measurements in 45 patients with symptomatic aortic stenosis. The correlations between transesophageal echocardiography and hemodynamics were dependent on the amount of valvular calcium, whereas the continuity equation correlated well with hemodynamics in all patients.
