  • Title: Usefulness of echocardiography in detection of subclinical carditis in acute rheumatic polyarthritis and rheumatic chorea.
    Author: Agarwal PK, Misra M, Sarkari NB, Gupta AK, Agarwal P.
    Journal: J Assoc Physicians India; 1998 Nov; 46(11):937-8. PubMed ID: 11229218.
    Abstract:
    Detailed echocardiographic analysis was performed in 10 children with first episode of acute rheumatic fever who presented with acute rheumatic polyarthritis or rheumatic chorea and had no clinically detectable evidence of active carditis. Significant changes were observed in the form of mitral valve prolapse with regurgitation in 3, aortic valve prolapse with regurgitation in 1 and mitral valve billowing without regurgitation in 1 patient each. A significant (p < 0.001) anterior mitral chordal elongation was observed in both the groups--rheumatic polyarthritis and chorea when compared with age and sex matched control subjects. Mitral annular diameter was found to be increased (p < 0.001) in patients presenting with polyarthritis alone. These observations of clinically silent but echocardiographically detectable element of carditis forms the basis of how patients of acute rheumatic fever develop permanent valvular deformities in their latter lives without revealing any cardiac affection earlier.
