OBJECTIVE: We sought to determine the prevalence of unsuspected, pre-existing valvular regurgitation in a large, heterogeneous population of patients referred for an echocardiogram.
METHODS: The echocardiograms of 6851 consecutive individuals without suspected valve disease were reviewed. Regurgitant severity was graded using a clinical composite of published methods and multiple logistic analyses were used to model various clinical variables.
RESULTS: The overall prevalence of moderate or greater mitral regurgitation (MR) was 11.7% in male patients and 12.5% in female patients. For mild or greater aortic insufficiency (AI), the prevalence was 18.9% in male patients and 19.7% in female patients. Both MR and AI increased exponentially as a function of age. Female sex predicted MR, but AI was sex neutral. Regurgitant severity increased with decreasing ejection fraction and body mass index, a history of hypertension, the presence of left ventricular hypertrophy, and valvular abnormalities.
CONCLUSIONS: The prevalence of unsuspected MR and AI is substantial, increases exponentially with age, and is predicted by commonly used clinical variables.
