Summary
Fulminating rheumatic carditis predominantly affects young Black patients, leading to severe heart failure primarily due to mitral valve regurgitation. Surgical repair is crucial, but medical treatments like steroids offer no survival benefit.
Area of Science:
- Cardiology
- Rheumatology
- Pediatric Cardiology
Background:
- Fulminating active rheumatic carditis presents consistently over three decades without changes in incidence or presentation patterns.
- The condition primarily affects Black patients, typically adolescents and children, with heart failure developing secondary to significant left-sided valve lesions.
Purpose of the Study:
- To analyze the clinical presentation, pathology, and management outcomes of fulminating active rheumatic carditis.
- To evaluate the efficacy of current treatment strategies, including medical and surgical interventions.
Main Methods:
- Retrospective analysis of patient data over three decades.
- Clinical assessment of valve lesions, hemodynamic status, and left ventricular function.
- Review of surgical outcomes for mitral valve repair versus replacement.
Main Results:
- Mitral regurgitation, stemming from mitral annular dilatation and anterior leaflet prolapse, is the predominant lesion.
- Heart failure is prevalent and necessitates surgical valve intervention.
- Mitral valve repair is preferred but not always feasible; steroid therapy is ineffective.
Conclusions:
- Active rheumatic carditis leads to severe valve disease and heart failure, requiring surgical management.
- Left ventricular dysfunction may result from valve lesions rather than a direct rheumatic myocardial effect.
- Effective management hinges on timely surgical repair of the affected valves.
