BACKGROUND: The strategy of isolated tricuspid valve surgery has undergone innovations in recent years. This study aimed to summarize our experience using an endoscopic approach to repeat isolated tricuspid valve surgery (RITS) after left-sided valve replacement (LSVR).
METHODS: From June 2013 to May 2019, 79 patients underwent endoscopic RITS after LSVR at our institution. Patients were divided into the tricuspid valvuloplasty (TVP) group (n = 49) and the tricuspid valve replacement (TVR) group (n = 30); perioperative outcomes and followup results were compared.
RESULTS: There were seven postoperative deaths (8.9%). In-hospital mortality was higher in the TVR group than in the TVP group, although this difference was not statistically significant (13.3% vs. 6.1%, P = 0.417). More patients experienced residual moderate-tosevere tricuspid regurgitation (TR) at discharge in the TVP group than in the TVR group (26.7% vs. 0%, P = 0.003). Five patients died from heart, and multiorgan failure during follow-up; the overall 3- and 5-year survival rates were 93.8% [95% confidence interval (CI): (87.1-99.9%)] and 85.3% (95% CI: 73.3-9.2%), respectively, and no significant differences were found between the two groups (P = 0.103). The overall rates of the 3- and 5-year freedom from severe recurrent TR were 93.2% (95% CI: 85.9-99.9%) and 89.0% (78.7-99.9%), respectively, and no significant difference was found between groups (P = 0.176).
CONCLUSIONS: Repeat isolated tricuspid valve surgery after left-sided valve replacement is associated with adverse perioperative outcomes. Endoscopic access offers an alternative approach for RITS after LSVR with acceptable results. TVP results in lower surgical mortality than TVR while carrying a higher risk of residual moderate-to-severe TR.
