Abstract 2266: Development of Tricuspid Regurgitation Late After Left-Sided Valve Surgery in Patients without Significant Preoperative Tricuspid Regurgitation :A Single-Center Experience with Long-term Echocardiographic Examinations
Aim: We investigated the incidence and predictors of tricuspid regurgitation (TR) development long after left-sided valve surgery in patients without significant preoperative TR.
Methods: Of 615 patients who underwent surgery for left-sided valve disease between 1992 and 1995, 335 patients without preoperative TR who completed at least 5 years of clinical and echocardiographic follow-up were enrolled. Late significant TR development was assessed by echocardiography with a mean follow-up duration of 11.6 ± 2.1 years.
Results: Significant late TR was found in 90 patients (26.9%). Patients with late TR showed; an advanced age, a higher prevalence of atrial fibrillation and prior valve surgery, and a greater left atrial dimension. In addition, late TR was more frequent in patients with mitral valve surgery. Systolic pulmonary artery pressure and mean right atrial pressure were not different between the groups. Multivariate analysis showed that the preoperative atrial fibrillation (OR 5.37; 95% CI. 2.71–10.65; p<0.001) was the only independent factor of late TR development. Patients that developed late TR had a lower event-free survival rate than those that did not (p=0.03).
Conclusion: The development of significant TR long after left-sided valve surgery is not uncommon and is associated with a poor prognosis. The preoperative atrial fibrillation is an independent predictor of the late TR.
