Conclusion
Observational studies suggest that surgical aortic valve replacement (SAVR) may offer better long-term survival compared to transcatheter aortic valve replacement (TAVR) in low-risk patients.
Supporting Evidence
- Observational studies reported significantly better survival after SAVR compared to TAVR.
- Thirty-day mortality after TAVR and SAVR were 0.6% and 1.3%, respectively.
- Kaplan–Meier estimate of 5-year all-cause mortality was 29.8% after TAVR and 16.9% after SAVR.
- SAVR was associated with significantly lower rates of cardiovascular death and stroke at 5 years.
- Data were retrieved from 2 national registries, ensuring reliability of long-term outcomes.
Takeaway
This study looks at two ways to fix a heart valve and finds that one method might help people live longer than the other, especially for those who are not very sick.
Methodology
The study compared outcomes of patients who underwent isolated SAVR or TAVR using a propensity score matching analysis.
Potential Biases
Potential biases related to patient selection and unmeasured confounding factors may affect the results.
Limitations
The study's retrospective nature and lack of data on coronary artery disease and patient frailty are significant limitations.
Participant Demographics
The mean age of the matched cohorts was 75 years, indicating a low-risk profile.
