May support strict Doppler criteria to identify pathologic silent mitral regurgitation in rheumatic fever; leaves open its role as a minor diagnostic criterion pending validation.
Can Doppler echocardiography distinguish between physiologic and pathologic 'silent' mitral regurgitation in patients with rheumatic fever?
Strict Doppler echocardiography criteria can accurately distinguish pathologic 'silent' mitral regurgitation in rheumatic fever from physiologic regurgitation, supporting its use as a minor diagnostic criterion.
