Right-sided endocarditis complicating peritoneovenous shunting for ascites.
We describe two patients with alcoholic cirrhosis in whom staphylococcal right-sided endocarditis developed after insertion of a peritoneovenous shunt (PVS). Massive pulmonary embolism caused early death in one patient. In the other patient, staphylococcal septicemia was cured after shunt removal and antibiotic treatment; recurrent endocarditis due to Corynebacterium xerosis ultimately caused the patient's death. No clinical manifestation of tricuspid valve dysfunction was noted in either patient, and right-sided endocarditis was recognized only at autopsy. The protracted contact of the tip of the venous line of PVS with the atrial wall is likely to be a major factor in the development of right-sided endocarditis in these patients.
