Heart valve study: is being awake or asleep better during procedure?

This study looked at 218 people with severe aortic stenosis (a narrowed heart valve) who needed a procedure called TAVI to replace the valve without open-heart surgery. Researchers compared two approaches: general anesthesia (being fully asleep) versus local anesthesia with sedation (being awake but relaxed). The goal was to see if general anesthesia was as safe and effective as the lighter sedation method, focusing on complications and recovery within the first 72 hours.
