Representative Pathological Images of THV Implant at 180 Days

Representative pathological images of a Myval transcatheter heart valve implant (THV) at 180 days. (Upper left)Arrows indicate implant cusps showing neointima formation. (Upper right) Stent frame. Arrows indicate fibrocellular endothelialized neointima covering the stent. (Lower left) Normal conformation of the implant cusps with coverage by slight to mild fibrocellular neointima (noncoronary [NC] and left coronary [LC] implant cusps). (Lower right)Arrows indicate diffuse coverage of the LC implant cusp by mature fibrocellular and endothelialized neointima. Dotted line indicates slight pannus formation. Open arrowheads indicate collagenous bioprosthetic material. Solid arrows indicate polyester pad showing minimal foreign body response. AV = aortic valve; RC = right coronary.
