Clinical and echocardiographic characteristics of patients treated for right-sided endocarditis are presented. Of 205 patients with infective endocarditis, 13 had involvement of the right heart structures. The predisposing factors for right-sided infective endocarditis in our group of patients were either severe debilitating disease (4 patients), or congenital heart disease (2 patients). In the majority of patients the disease was linked to invasive medical procedures such as central intravenous lines, pace-maker and an abortion in one case. None of the patients was an intravenous drug user. The tricuspid valve was affected in eight patients and pulmonary valve in three. In one patient, the endocardium at the right side of the ventricular septal defect was involved. One patient had a pace-maker electrode infection. Pulmonary embolisms were the major complication of the disease. A transthoracic echocardiogram confirmed the diagnosis in all patients with tricuspid valve infective endocarditis, while vegetations were present in only one patient with pulmonary valve infective endocarditis. Four patients died. Right-sided infective endocarditis in non drug addicts is a severe disease with high mortality rate, and should be suspected in patients with pulmonary embolism and signs of infective endocarditis, especially in those with a predisposing condition, even if they are not intravenous drug addicts.
