Abstract
BACKGROUND: Surgery for isolated tricuspid valve (TV) disease remains relatively infrequent because of significant patient comorbidities and poor surgical outcomes. This study reviewed the experience with isolated TV surgery in the current era to determine whether outcomes have improved. METHODS: From 2007 through 2017, 685 TV operations were performed in a single institution, of which 95 (13.9%) operations were isolated TV surgery. Patients were analyzed for disease origin, risk factors, operative mortality and morbidity, and long-term survival. RESULTS: A total of 95 patients underwent isolated TV surgery, an average of 9 patients per year increasing from an average of 5 per year to 15 per year during the study period. Surgery was reoperative in 41% (38 of 95) of patients, including 11.6% (11 of 95) with prior coronary artery bypass grafting and 29.4% (28 of 95) with prior valve surgery (9 TV, 11 mitral, 2 aortic, 5 mitral and aortic, and 1 mitral and TV). Repair was performed in 71.6% (68 of 95) of patients, and replacement was performed in 28.4% (27 of 95). Operative mortality was 3.2% (3 of 95), with no mortality in the most recent 73 patients over the last 6 years. Stroke occurred in 2.1% (2 of 95) of patients, acute kidney injury requiring dialysis in 5.3% (5 of 95), and the need for new permanent pacemaker in 16.8% (16 of 95). CONCLUSIONS: In the current era with careful patient selection and periprocedural management, isolated TV surgery can be performed with lower morbidity and mortality than has traditionally been reported with good long-term survival. These outcomes can also serve as a benchmark for catheter-based TV intervention outcomes.
