Stentless implants offer increased flexibility and haemodynamic performance, and ensure that the shape of the valve or root conforms to the patient's own aorta, allowing natural tissue geometry.

Key features:
• Reduced distortion during implantation
• Approximates patient's own valve anatomy
• Reduced aortic wall thickness by removal of excess ventricular muscle
• Pericardium reinforcement for greater durability
• Increased flexibility and haemodynamic performance
• Sewing cuff provides a guide for implanting surgeons
• The root may also be tailored by the surgeon to accommodate individual patient's anatomical idiosyncrasies
