Randomized Controlled TrialDurability of Transcatheter and Surgical Bioprosthetic Aortic Valves in Patients at Lower Surgical Risk.
Transcatheter aortic valve replacement (TAVR) is an alternative to surgical aortic valve replacement (SAVR) in patients with severe aortic stenosis and intermediate or high surgical risk. ⋯ In the NOTION trial through 6 years, SVD was significantly greater for SAVR than TAVR, whereas BVF was low and similar for both groups. Longer-term follow-up of randomized clinical trials will be necessary to confirm these findings. (Nordic Aortic Valve Intervention Trial; NCT01057173).
