Unsuspected rheumatic fever carditis ending in heart transplantation.

A 25-year-old female patient with presumed peripartum cardiomyopathy was submitted after two years to orthotopic heart transplantation. Pathological examination of the excised heart revealed acute rheumatic fever. Five days after the transplantation persistent fever developed. The patient's condition deteriorated until death after six weeks, which was attributed to cytomegalovirus disease.
