Figure 1: .
Continuous wave Doppler recording of aortic jet velocity in an elderly patient with severe aortic stenosis. Non-invasive Doppler evaluation of jet velocity, mean pressure gradient, and valve area are key to the evaluation and management of adults with aortic stenosis.
Figure 2: .
Kaplan-Meier survival curves for patients with aortic stenosis and reduced left ventricular function with and without significant coronary artery disease (two vessel disease or greater or left main coronary disease) in comparison with expected survival. Number of patients alive at each point is shown on the x axis. CAD, coronary artery disease. Reproduced with permission from Connolly HM, et al. Circulation 1997;95:2395-400.
Figure 3: .
Cox regression analysis showing event free survival in 123 initially asymptomatic adults with valvar aortic stenosis, defined by aortic jet velocity at entry (p < 0.001 by log rank test). Reproduced with permission from Otto CM, et al. Circulation 1997;95:2262-70.
Figure 4: .
Colour flow Doppler image showing severe aortic regurgitation with a broad regurgitant jet and dilated left ventricle in a patient with a bicuspid aortic valve. Doppler measures of regurgitant severity are most helpful in identifying patients in whom periodic evaluation of left ventricular size and systolic function is warranted.
Figure 5: .
Cumulative actuarial incidence of progression to aortic valve replacement in 143 initially asymptomatic patients with severe aortic regurgitation randomised to treatment with digoxin 0.25 mg daily or nifedipine 20 mg twice a day. Reproduced with permission from Scognamiglio et al.8
