Persistent hypoxemia occurring as a complication of tricuspid valve endocarditis

A 33-year-old woman had intravenous drug-associated tricuspid valve infecti ve endocarditis. Despite resolution of septic pulmonary emboli, hypoxemia p ersisted. We report a case of right-to-left shunting across a previously in significant patent foramen ovale documented by contrast transesophageal ech ocardiography. Although a rare complication of tricuspid endocarditis, clin icians should be aware of this potential correctable complication.
