High resolution, photorealistic 3D medical product render of a balloon expandable transcatheter aortic valve prosthesis, isolated on a pure white seamless background with a very soft gray ground shadow. Centered, three quarter front view, slightly above eye level.

The device is a short cylindrical stent frame made of thin metallic struts in a diamond lattice pattern, brushed silver with clean specular highlights. At the base is a thick off white fabric sealing skirt that wraps the circumference, with a subtle woven texture and a scalloped lower edge. Inside the stent are three pale cream bioprosthetic leaflets, slightly translucent, with realistic thickness and soft folds, arranged symmetrically and open in a relaxed neutral position.

Include thin dark gray commissure posts and small wire details at the top edge. Clean studio lighting, crisp focus, no text, no watermark, no logo, no hands, no anatomy.
