A 35 year-old male patient developed a subphrenic abscess in the immediate postoperative period after replacement of a calcified mitral bovine pericardium bioprosthesis. He was successfully treated with abdominal percutaneous drainage and antimicrobial therapy.

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.
