Impact of Tricuspid Regurgitation on Outcomes of Transcatheter Aortic Valve Replacement With Balloon-Expandable Valves
Authors' conclusion
Severe baseline and 30-day residual TR after TAVR are associated with increased mortality up to 3 years.
Study context
- Population
- Patients with AS undergoing transcatheter aortic valve replacement (TAVR) (balloon-expandable valves), CMS-linked TVT Registry84% mild, 13% moderate, 3% severe tricuspid regurgitation (TR)
- Participants
- 312,320 patients
- Exposure
- Severe vs moderate vs mild baseline TR in TAVR
- Outcome
- Mortality by baseline TR severity
- Follow-up
- Up to 3 years
Methodological detailspropensity-score matched, registry-based (CMS-linked TVT Registry)

Main finding
As reported in the abstract
Mortality by baseline TR
In-hospital mortality
1-year mortality
3-year mortality
Observational data: associations, not effects.
Further findings
1-year mortality by 30-day residual TR
| Outcome | Severe TR | Moderate TR | Mild TR |
|---|---|---|---|
| TR improvement to moderate or less at 30 days (severe baseline TR) · 30 days after TAVR | 76.4% | — not stated in the abstract | — not stated in the abstract |
— not stated in the abstract
- 1-year mortality by 30-day residual TR: P < 0.0001
Predictors of TR improvement after TAVR
- Baseline MR moderate or greater, preserved EF, higher aortic valve gradient and better kidney function predicted TR improvement
