Ultrasound-Guided vein puncture studied for safer heart procedure
NCT ID NCT06403527
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether using ultrasound to guide vein puncture reduces complications like bleeding or false aneurysms in people undergoing ablation for atrial fibrillation. Over 1,000 adults scheduled for the procedure were enrolled. The study was terminated early, so results are limited.
