This meta-analysis aims to compare the long-term follow-up after TAVR versus surgical aortic valve replacement (SAVR) in low-risk patients. We searched databases up to July 7, 2024 for randomized clinical trials comparing TAVR versus SAVR in low-risk patients (defined as Society of Thoracic Surgeons Predicted Risk of Mortality score &lt;4%) (PROSPERO ID: CRD42023480495). Primary outcome analyzed was all-cause death at a minimum of 3 years of follow-up. The secondary outcomes were cardiovascular death, disabling stroke, myocardial infarction, aortic valve reintervention, endocarditis, new-onset atrial fibrillation, permanent pacemaker implantation, and bioprosthetic valve failure. A total of 3 randomized clinical trials with 2,644 patients (TAVR n = 1,371 patients; SAVR n = 1,273 patients) were included. The follow-up time was 6 ± 2.9 years. TAVR resulted noninferior to SAVR for all-cause death (risk ratio [RR] 0.99, 95% confidence interval [CI] 0.84 to 1.17, p = 0.89, I² = 28%), cardiovascular death (RR 0.94, 95% CI 0.76 to 1.15, p = 0.54, I² = 0%), myocardial infarction (RR 1.06, 95% CI 0.71 to 1.57, p = 0.79, I² = 61%), aortic valve reintervention, endocarditis, and bioprosthetic valve failure.

There was no significant difference in AoD at rest between subjects with HF and controls. However, immediately after exercise, participants with HF but not controls exhibited a significant reduction in AoD, indicating higher aortic stiffness related to exercise (median [interquartile range] for the ascending aorta: 3.16 (1.26) × 10⁻³ mm Hg⁻¹ to 2.39 (1.57) × 10⁻³ mm Hg⁻¹ and the descending aorta: 4.19 (2.58) × 10⁻³ mm Hg⁻¹ to 2.96 (1.79) × 10⁻³ mm Hg⁻¹) (both p = 0.023).
