BACKGROUND: The aim of this study was to investigate lead endocarditis-related tricuspid valve regurgitation, to identify underlying causes, and to report our surgical approaches to tricuspid valve endocarditis. METHODS: Between March 2010 and August 2016, medical records of a total of 43 patients (23 males, 20 females; mean age: 63.2±13.6 years; range 48 to 72 years) who underwent tricuspid valve surgery for severe tricuspid regurgitation caused by lead endocarditis, which was previously placed as an implantable cardiac electronic device were reviewed. We removed all systems including infected leads and generators, revised infected wounds and tissues, performed tricuspid valve surgery for lead endocarditis, and applied long-term intravenous antibiotic regimen for the culprit agent, as confirmed by the culture. RESULTS: Of 43 patients, 18 underwent tricuspid valve repair and 25 underwent tricuspid valve replacement for lead endocarditisrelated severe tricuspid valve regurgitation. During followup (range, 2 to 62 months), two patients required temporary mechanical support due to postoperative acute right heart failure, while eight patients died due to sepsis (n=6; 14%) and stroke (n=2; 4.6%) in the early postoperative period. The remaining patients showed significant improvement in signs and symptoms of heart failure. CONCLUSION: Our study results suggest that incompetent experience and inaccurate decision for valve repair may result in delayed valve replacement and prolonged operation time.
