Background and aim of the study: Isolated bacterial tricuspid valve (TV) endocarditis is usually managed medically. Whilst the indications and optimal timing for surgical treatment of the condition have not been clearly defined, it is hypothesized that early surgery in patients who are bacteremic and/or have evidence of systemic seeding is superior to medical treatment.

Methods: All cases of isolated TV endocarditis reported between 2006 and 2011 at the authors’ institution were reviewed. Patients with bacteremia and/or systemic seeding who were treated surgically after short-term medical therapy were compared to an equivalent group of patients who remained under long-term medical treatment only.

Results: A total of 45 patients with isolated TV endocarditis showed evidence of bacteremia and/or systemic seeding. Of these patients, 10 (22.2%) were treated surgically with valve repair or replacement, and 35 (77.8%) received long-term medical therapy only. The 30-day and one-year survival rates in both groups were comparable (100% versus 88.6%, p = 0.27).

Patients treated surgically had clear blood cultures sooner (2.0 versus 6.7 days, p = 0.04), defervesced earlier (0 versus 9.0 days, p = 0.02), and demonstrated a complete resolution of TV vegetations (100% versus 30.0%, p = 0.003). Change in creatinine clearance (+22.1 versus +11.6 ml/min, p = 0.40) and durations of vasopressor support (6.8 versus 8.9 h, p = 0.86), mechanical ventilation (8.5 versus 32.2 h, p = 0.44), ICU stay (148.1 versus 53.8 h, p = 0.14) and total hospital stay (32.1 versus 24.6 days, p = 0.22) were not different between groups. Long-term echocardiogram surveillance demonstrated a higher prevalence of moderate-severe tricuspid regurgitation in the medically treated patients (75.0 versus 0.0%, p <0.001). None of the patients treated surgically was readmitted with prosthetic valve endocarditis.

Conclusion: Early surgery is warranted in patients with isolated TV endocarditis who are bacteremic and/or systemically infected despite optimal medical therapy.
