Key result
Cardiac surgery for isolated tricuspid valve endocarditis resulted in a 30-day mortality of 3.1% and a 5-year overall survival of 76.9%.
Why the study?
Isolated tricuspid valve endocarditis is usually managed medically, requiring surgical intervention only in specific cases, leaving data on surgical outcomes sparse.
What are the midterm survival and reoperation outcomes following surgical treatment for isolated tricuspid valve endocarditis?

What are the midterm survival and reoperation outcomes following surgical treatment for isolated tricuspid valve endocarditis?
Surgical treatment for isolated tricuspid valve endocarditis is associated with a 30-day mortality of 3.1% and allows for valve repair in 50% of cases, though replacement is more frequent when the subvalvular apparatus is involved.
Adds limited observational data on surgical TVE outcomes; leaves open optimal indications and long-term benefit.
BACKGROUND: Isolated tricuspid valve endocarditis (TVE) is a rare disease which is managed medically in most patients. Only in specific cases, surgical intervention becomes necessary. Hence, data about surgical outcomes are sparse. This study reports on the operative experience in patients with isolated TVE over a period of 20 years. METHODS: We retrospectively analyzed 32 patients with isolated TVE who underwent surgery from February 2001 to June 2021 at the German Heart Centre Munich. RESULTS: Thirty-day mortality was 3.1%. Overall survival was 89.9± 5.5% at 1 year and 76.9 ± 8.5% at 5 years. Cumulative incidence for reoperation was 11.1 ± 6.0% at 5 years. Four patients (12.5%) were treated for recurrent endocarditis. Tricuspid valve repair (TVr) was achieved in 16 patients (50%). If the subvalvular apparatus (n = 10) was involved, tricuspid valve replacement was performed more frequently. CONCLUSIONS: Mortality in patients with isolated TVE undergoing cardiac surgery is high. In half of the cases, TVr was achieved but was less likely in patients with affected subvalvular apparatus.

Dzilic et al. (2022) conducted a cohort in Isolated tricuspid valve endocarditis (n=32). Cardiac surgery was evaluated on 30-day mortality. Cardiac surgery for isolated tricuspid valve endocarditis resulted in a 30-day mortality of 3.1% and a 5-year overall survival of 76.9%.
