High resolution, photorealistic 3D medical illustration of a balloon-expandable transcatheter aortic valve prosthesis deployed inside a surgical cutaway of the human heart.

The view is from inside the left ventricle looking toward the aortic root. The heart tissue shows thick, moist endocardial surfaces with realistic texture and coloration. The valve is seated at the aortic annulus with the fabric sealing skirt interfacing with the native tissue in a clinically plausible manner.

The device features a short cylindrical stent frame with metallic diamond lattice struts, three pale cream bioprosthetic leaflets in neutral position, and thin dark commissure posts.

A delivery catheter with marker rings is visible, connected to a continuous guidewire. Clinical studio lighting with controlled reflections, shallow depth of field, no text, no watermark, no logo.
