Percutaneous aortic valve replacement: gross anatomy and histological findings after transapical and endoluminal resection of human aortic valves in situ☆☆☆

Abstract

This study shows fewer severe lesions in the aorta after transapical antegrade access compared to the transluminal retrograde approach. Especially noteworthy is that the aortic arch remains unaffected by the transapical procedure. These data demonstrate the transapical approach as less hazardous.

Percutaneous aortic valve replacement: valvuloplasty studies in vitro

“…In addition, debris also occurs during the placement of the whole delivery system. In a recent in vitro study, it could be shown that there are more plaque ruptures and aortic lesions using a transfemoral approach [12].…”

Papillary muscle rupture

“…Nevertheless, the transfemoral anterograde approach has been nowadays replaced by the retrograde. However, transapical implantation is antegrade and could be more prone to these complications [8].…”

Transcatheter Aortic Valve Implantation Outcomes

“…Promising TAVI advancements include reduced valve profiles, techniques to reduce paravalvular AR, endoluminal resection of diseased aortic valve leaflets to avoid valvuloplasty, 101 and the ability to retrieve and reposition the valve before final deployment.…”
