Abstract

echocardiography pulmonary valve endocarditis right heart endocarditis tricuspid valve endocarditis
The echocardiographic findings were correlated with the clinical findings and outcome in 23 patients with tricuspid valve or pulmonary valve endocarditis. There were 15 males and 8 females with a mean age of 33.1 ± 8.4 years. Eighteen patients had tricuspid valve endocarditis, 1 patient had pulmonary valve endocarditis, 3 patients had concomitant mitral valve and tricuspid valve endocarditis, and 1 patient had tricuspid valve and pulmonary valve endocarditis. Twenty of the 23 (87%) patients had a history of intravenous drug abuse. The most common organisms were Staphylococcus aureus (10 of 23 patients or 43%), Streptococcus viridans (5 patients) and Pseudomonas aeruginosa (4 patients). Pulmonary manifestations with septic pulmonary emboli were present in 18 23 (80%) patients, and a regurgitant murmur in 16 23 (73%) patients. Vegetations on the tricuspid valve or pulmonary valve were detected in all patients who had 2D echo, but they were missed by M-mode echo in 2 patients. Nine of the 23 patients (40%) improved on medical therapy, 5 (21%) expired, and 7 (30%) required surgery (tricuspid valve or pulmonary valve replacement in 3, and tricuspid valve excision without replacement in 4). Conclusions: (1) 11 of 13 patients with persistent infection, multivalvular involvement, fungal or Pseudomonas infection and increasing size of vegetations by echo died or underwent surgery compared to only 1 of 8 patients without these features ( P < 0.01). (2) Staphylococcus aureus infection (10 patients) and flail tricuspid valve or pulmonary valve by echo (6 patients) were not predictive of outcome.
