Implication
These predictors identify high-risk patients for recurrent TR post-annuloplasty; leaves open optimal strategies to enhance repair durability.
Key Points
- This study aimed to identify echocardiographic predictors of recurrent tricuspid regurgitation after annuloplasty.
- Included 39 patients with functional TR undergoing echocardiography before, early after, and over a year post-annuloplasty.
- Measured TR severity, TV annular dimensions, leaflet displacement, and ventricular functions.
- Analyzed how preoperative and early postoperative measurements correlate with long-term TR outcomes.
- Preoperative leaflet tethering height and area predicted early and mid-term TR outcomes.
- Early postoperative left ventricular ejection fraction and TR severity significantly influenced late TR degree.
- Higher right ventricular pressure correlated with worse TR during follow-up.

Preoperative tricuspid valve tethering, along with left and right ventricular function and pressures, are key determinants of repair durability after tricuspid annuloplasty.
