[Isolated endocarditis of the tricuspid valve in early infancy]

A newborn baby is admitted in the second week of life with osteomyelitis and septicemia due to Staph. aureus infection. In his tenth week of life--the osteomyelitis nearly overcome--the infant shows signs of heart failure with a murmur and cyanosis. Cardiac catheterization reveals tricuspid insufficiency and thrombosis of the right pulmonary artery. Postmortem examination shows isolated polypous endocarditis of the tricuspid valve together with thrombosis of the right and recent embolus of the left pulmonary artery. A similar case has to the best of our knowledge not been described.
