Pseudallescheria boydii endocarditis of the pulmonic valve in a liver transplant recipient.
We describe a case of Pseudallescheria boydii endocarditis involving the pulmonic valve in an orthotopic liver transplant recipient. The patient required transplantation because of hepatic failure secondary to chronic active hepatitis B. His postoperative course was complicated by surgery for gastric and duodenal ulcers, persistent fever, and, ultimately, sepsis leading to oliguric renal failure. Two days before death, the patient experienced complete heart block, and an echocardiogram revealed pulmonic valve thickening and an endocardial mass along the left side of the septum. At autopsy the patient was found to have a vegetation on the pulmonic valve and a septal abscess. There were multiple fungal emboli found throughout other organs, and P. boydii was obtained on culture. This unique association between pulmonic valve endocarditis and myocardial septal abscess is discussed. In addition, review of the five previous cases of P. boydii endocarditis reveals that this rare infection is associated with immunosuppression and prosthetic devices.
