Different anchoring mechanisms of self-expanding valves during TAVR in patients with AS and PNAR

(a) Anchoring of TAV prosthesis in patients with AS mainly relies on aortic annulus, calcified valve leaflets, and STJ; (b) anchoring of TAV prosthesis in PNAR relies on LVOT, aortic annulus, thickened aortic valve leaflet (if there is a thickening of the valve leaflets), and STJ.

AA: ascending aorta; AS: aortic stenosis; LA: left atrium; LV: left ventricle; LVOT: left ventricular outflow tract; PNAR: pure native aortic regurgitation; RV: right ventricle; STJ: sinotubular junction; TAV: transcatheter aortic valve; TAVR: TAV replacement
