Native aortic valve regurgitation: TAVR’s place in the PANTHEON

The PANTHEON (Performance of Currently Available traNscaTHEter Aortic Valve Platforms in Inoperable Patients With Pure Aortic regurgitatiON of a native valve) study examined transcatheter aortic valve replacement in patients with severe pure native aortic valve regurgitation. With a real-world dataset from 16 centres in Europe and the USA, the study encompassed 201 patients. The major complications included valve embolization or migration in 12.4%, moderate to severe aortic regurgitation in 9.5% cases and need for permanent pacemaker in 22.3% cases. Self-expanding and balloon-expandable devices demonstrated similar outcomes. Those experiencing valve embolization or migration had higher 1-year adverse event rates.
