Infective endocarditis is a rare disease in infants. A 1-year-old boy with a large Candida albicans vegetation in the right atrium and superior vena cava was operated on successfully. During the newborn period he had had a right transverse colostomy for Hirschsprung's disease. Ten months later a subsequent rectosigmoidectomy and direct anastomosis were performed, but because of peritonitis that followed a leak at the site of the anastomosis parenteral nutrition was needed for 8 weeks. The probable source of Candida was an infected intravenous line.
