Efficacy of echocardiographic criteria for diagnosis of carditis in acute rheumatic fever.

ABSTRACT

Background: There is a great need forECHOcriteria for accurate diagnosis of carditis in acute rheumatic fever. Aim: To propose and test the efficacy of ECHO criteria for accurate diagnosis of carditis. Material and Methods: The 333 cases underwent detailed clinical examination, laboratory tests and meticulous Echocardiographic study.Vijay’s ECHO criteria for the diagnosis of carditis / subclinical valvulitis was used. 220 (66.06%) cases were both Jones’ positive and ECHO positive [True +ve], 52 cases (15.61%), probably had subclinical carditis as murmur was not heard (Jones’-ve) but ECHO was positive [False - ve]. Four cases, clinically diagnosed as carditis were Jones’+ve ,but ECHO showed congenital heart disease [False +ve]. 57 cases (17.11%) were clinically , echocardiographically and Jones’ negative were taken as control (True –ve). Sensitivity is81%and specificity is 93%. Conclusions: Precise diagnosis of both carditis /subclinical valvulitis is possible with Vijay’s ECHO criteria. ECHO should be included as a major criterion in Jones’criteria.
