Abstract:
We report the first case in the English language literature, to our knowledge, of native valve endocarditis due to Legionella pneumophila. The patient had no prior history of cardiothoracic intervention or congenital valvular process. A transesophageal echocardiogram showed a vegetation on the aortic valve. Blood culture and bronchoalveolar lavage returned positive for L. pneumophila. The patient was treated with levofloxacin for 6 weeks total after a second set of blood cultures were negative. The patient survived a complicated hospital course and was discharged to a rehabilitation facility.
