Does tricuspid annuloplasty alter right heart flow dynamics and prevent tricuspid regurgitation in patients with atrial fibrillation?
Tricuspid annuloplasty using the modified De Vega technique provides sustained reduction in tricuspid regurgitation but may induce mild tricuspid stenosis.
Supports sustained TR reduction with mild stenosis risk after annuloplasty in AF; leaves open randomized confirmation of clinical outcomes.
To evaluate the effect of tricuspid annuloplasty (TAP) on right heart flow dynamics, we analyzed tricuspid inflow velocity pattern, jugular venous pulse and color Doppler flow signal of tricuspid regurgitation (TR) before and after surgery in 16 patients who underwent TAP (TAP group). Cardiac rhythm was atrial fibrillation in all patients. Twelve patients with lone atrial fibrillation served as controls (AF group). Patients in the TAP group were studied before and serially after surgery with a mean follow-up period of 2.7 years. TAP was performed according to the modified De Vega technique in all patients. In a comparison of the most recent data in the TAP group and the data in the AF group, the maximum tricuspid inflow velocity was significantly increased, and both the deceleration time of the tricuspid inflow velocity wave and the y-h interval of the jugular venous pulse were significantly prolonged in the TAP group compared to the AF group. Immediately after surgery, in the TAP group, the area of the TR jet was markedly decreased, and the deceleration time of the tricuspid inflow velocity wave was significantly prolonged compared to those before surgery. The area of the TR jet was dramatically decreased and remained small during the follow-up period. Thus, TAP may produce mild tricuspid stenosis but may also confer sustained preventive effects against TR.

Fukuda et al. (1998) conducted an observational in Tricuspid regurgitation (n=28). Tricuspid annuloplasty vs. Preoperative baseline and lone atrial fibrillation controls was evaluated on Tricuspid inflow velocity, deceleration time, and tricuspid regurgitant jet area (p=<0.05). Tricuspid annuloplasty markedly decreased tricuspid regurgitation jet area for up to 5 years, while inducing a mild increase in maximum tricuspid inflow velocity and prolonged deceleration time indicative of mild tricuspid stenosis.
