This study aims to compare valve durability between transcatheter aortic valve implantation (TAVI) and surgical aortic valve replacement (SAVR).

Methods

We conducted a systematic review and meta-analysis using data from randomized controlled trials (RCTs). The primary outcome was structural valve deterioration (SVD). Secondary outcomes were bioprosthetic valve failure, reintervention, effective orifice area (EOA), mean pressure gradient, and moderate–severe aortic regurgitation (AR, transvalvular and/or paravalvular).

Results

Twenty-five publications from seven RCTs consisting of 7,970 patients were included in the analysis with follow-up ranges of 2–8 years. No significant difference was found between the two groups with regard to SVD [odds ratio (OR) 0.72; 95% CI: 0.25–2.12]. The TAVI group was reported to exhibit a statistically significant higher risk of reintervention (OR 2.03; 95% CI: 1.34–3.05) and a moderate–severe AR (OR 6.54; 95% CI: 3.92–10.91) compared with the SAVR group. A trend toward lower mean pressure gradient in the TAVI group [(mean difference (MD) −1.61; 95% CI: −3.5 to 0.28)] and significant higher EOA (MD 0.20; 95% CI: 0.08–0.31) was noted.

Conclusion

The present data indicate that TAVI provides a comparable risk of SVD with favorable hemodynamic profile compared with SAVR. However, the higher risk of significant AR and reintervention was demonstrated.
