Adult-onset acute rheumatic fever with chorea and carditis.

Rheumatic fever is a major cause of cardiovascular morbidity and mortality in low-income and middle-income countries, and it usually occurs at a young age. Adult-onset acute rheumatic fever is a rare condition and usually represents a recurrence of childhood-onset disease. We report a case of an elderly man presenting with rheumatic carditis and rheumatic chorea subsequently diagnosed with adult-onset rheumatic fever.
