Article Synopsis
- The meta-analysis compares long-term outcomes of transcatheter aortic valve replacement (TAVR) and surgical aortic valve replacement (SAVR) in low-surgical risk patients with severe aortic stenosis.
- TAVR showed lower all-cause mortality risk within 30 days and up to one year compared to SAVR, but risks were similar after one year.
- Additionally, TAVR had lower rates of cardiovascular mortality, disabling strokes, rehospitalizations, and new-onset atrial fibrillation, but a higher chance of needing a permanent pacemaker, especially in the first 30 days.
Background Proximal radial artery (pRA) access for cardiac catheterization is safe but can jeopardize subsequent use of the artery because of occlusion. Distal radial artery (dRA) access in the anatomical snuffbox preserves the radial artery, but safety and potential detrimental effects on hand function are unknown. Methods and Results In the DIPRA (Distal Versus Proximal Radial Artery Access for Cardiac Catheterization and Intervention) study, a single-center trial, 300 patients were randomized 1:1 to cardiac catheterization through dRA or pRA.
