Comparison of valve durability and outcomes of transcatheter aortic valve implantation versus surgical aortic valve replacement in patients with severe symptomatic aortic stenosis and less-than- high-risk for surgery

Abstract

This study aimed to investigate the rate of severe structural valve deterioration (SVD) and long-term outcomes of patients with severe symptomatic aortic stenosis undergoing transcatheter aortic valve implantation (TAVI) or surgical aortic valve replacement (SAVR). It was a propensity score matched analysis of patients who underwent TAVI (n = 216) and SAVR (n = 216) between 2008 and 2012. Long-term echocardiographic parameters and clinical outcomes were assessed after more than 6 years after TAVI/SAVR. Rate of severe SVD was 10.5% versus 4.5% in the TAVI and SAVR groups, respectively, but the difference was not statistically significant (hazard ratio [HR] 2.5; 95% confidence interval [CI] 0.7 to 8.3; p = 0.159). This was largely driven by higher rates of mean transprosthetic gradient ≥40 mm Hg (7.0 vs 3.4%; p = 0.327) and aortic regurgitation (4.7% vs 0%; p = 0.058). TAVI patients had lower survival rates at 6 years than SAVR patients (40.7% vs 59.6%, respectively, p <0.001, HR 2.15; 9 ...
