The prompt
How can we reduce from design point of view the following significant challenges for current human made implants like 1. Coronary Obstruction: A rigid cylindrical frame can push the native valve tissue outward, blocking flow to the coronary ostia. 2. Paravalvular Leak (PVL): Standard circular frames do not always seal tightly against asymmetric, calcified patient anatomy. 3. Sinus Sequestration: Implants can block normal blood pooling behind the leaflets, raising the risk of blood clots.
