Frequency of echocardiograms in asymptomatic patients with VHD and normal left ventricular function

Frequency of echocardiograms in asymptomatic patients with VHD and normal left ventricular function
Stage Valve lesion
Aortic stenosis* Aortic regurgitation Mitral stenosis Mitral regurgitation
Progressive (stage B) Every 3 to 5 years (mild severity Vmax 2.0 to 2.9 m/second) Every 3 to 5 years (mild severity) Every 3 to 5 years (MVA >1.5 cm2) Every 3 to 5 years (mild severity)
Every 1 to 2 years (moderate severity Vmax 3.0 to 3.9 m/second) Every 1 to 2 years (moderate severity) Every 1 to 2 years (moderate severity)
Severe (stage C) Every 6 to 12 months (Vmax ≥4 m/second) Every 6 to 12 months Every 1 to 2 years (MVA 1.0 to 1.5 cm2) Every 6 to 12 months
Dilating LV: more frequently Once every year (MVA <1.0 cm2) Dilating LV: more frequently
Patients with mixed valve disease may require serial evaluations at intervals earlier than recommended for single valve lesions.
VHD: valvular heart disease; LV: left ventricle; MVA: mitral valve area; Vmax: maximum velocity.
* With normal stroke volume.
