Implication
Supports high specificity of systolic anterior motion for hypertrophic cardiomyopathy in other cardiac diseases; leaves open prospective validation.
Structured PICO
What is the specificity of systolic anterior motion of the anterior mitral leaflet for hypertrophic cardiomyopathy in patients with other cardiac diseases?
P
Population
721 patients with a wide variety of cardiac diseases
I
Intervention
Echocardiographic evaluation for systolic anterior motion of the anterior mitral leaflet under basal conditions
O
Outcome
Presence or absence of systolic anterior motion of the anterior mitral leafletsurrogate
Systolic anterior motion of the anterior mitral leaflet is highly specific for hypertrophic cardiomyopathy, especially in patients with normal septal-free wall thickness ratios and without d-transposition of the great vessels.
