The Types segment classifies aortic valves by material composition and functional design, principally into mechanical, bioprosthetic (tissue), and emerging polymeric valves. Mechanical valves, constructed from pyrolytic carbon, command a premium due to their durability exceeding 20 years, yet they represent a smaller revenue slice (approximately 20 %) because of lifelong anticoagulation requirements that limit patient acceptance. Bioprosthetic valves, derived from bovine or porcine pericardium, dominate the market with an estimated 75 % share, reflecting clinician preference for reduced postoperative management and expanding use in TAVI platforms. Polymeric valves, still in clinical validation, occupy a nascent 5 % segment but are projected to grow as manufacturers address durability and thrombogenicity concerns. Each type’s contribution to market size is quantified by unit price differentials, adoption rates, and procedural volume, shaping the overall market taxonomy. Understanding the interplay among these valve types is essential for forecasting demand, investment decisions, and competitive positioning within the Aortic Heart Valve market.
