Abstract 3239: Edge-to-edge Repair of Functional Tricuspid Regurgitation is Safe and Durable
Introduction: The edge-to-edge repair technique has been well described for the treatment of functional mitral regurgitation, but few data exist describing its use in functional tricuspid regurgitation (FTR).
Hypothesis: The objective of this study was to describe early results of the edge-to-edge repair technique as surgical therapy for FTR.
Methods: Between October 2001 to March 2009, 104 patients underwent surgical repair of FTR by a single surgeon (15 edge-to-edge + tricuspid annuloplasty, 48 tricuspid annuloplasty alone, 41 DeVega repair alone). Mean patient age was 68.5±10.3 years and mean follow up was for 2.2±1.9 years (maximum 6.8 years). Parametric and semi-parametric tests were used to assess outcomes.
Results: There was one thirty-day death (1%). Patients receiving edge-to-edge repair for functional TR were more likely to possess severe (4+) TR preoperatively (11/89 versus 4/15; P=0.008), and be older (75.1±1.8 years vs. 67.4±1.1 years; P=0.006). In follow up, recurrent (≥2+) TR was observed in 19 patients (18%). Predictors of recurrent TR included postoperative pulmonary hypertension (>40 mm Hg) (Odds Ratio 15.7; P=0.004), but not tricuspid valve repair type. Valve repair type was also not predictive of survival (P=0.5)
Conclusion: Edge-to-edge repair of the tricuspid valve is safe and durable in early follow-up. Postoperative pulmonary hypertension significantly impacts recurrence of TR.
