Abstract

Background: Patients with isolated tricuspid regurgitation (TR) in the absence of left-sided valvular dysfunction are historically managed nonoperatively. Objectives: To assess the impact of surgery for isolated TR, we compared survival for isolated severe TR patients who underwent surgery to those who did not. Methods: A longitudinal echocardiography database was used to perform a retrospective analysis on 3,276 adult patients with isolated severe TR from November 2001-March 2016. All-cause mortality for patients who underwent surgery versus those who did not was analyzed in the entire cohort and a propensity-matched sample. To assess the possibility of immortal time bias, the analysis was performed considering time from diagnosis to surgery as a time-dependent covariate. Results: Of 3,276 patients with isolated severe TR, 171 (5%) underwent tricuspid valve surgery, including 143 (84%) repairs and 28 (16%) replacements. The remaining 3,105 (95%) patients were medically managed. When considering surgery as a time-dependent covariate in a propensity matched sample, there was no difference in overall survival between patients who received medical versus surgical therapy (HR 1.34 [0.78–2.30], p=0.288). In the subgroup that underwent surgery, there was no difference in survival between tricuspid repair versus replacement (HR 1.53 [0.74–3.17], p=0.254). Conclusion: In patients with isolated severe TR, surgery is not associated with improved long-term survival compared to medical management alone after accounting for immortal time bias.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
