Transcatheter Heart Valve Therapies segmentation by type categorises devices into balloon‑expandable, self‑expanding, and mechanically expandable systems. Balloon‑expandable valves, chiefly employed in TAVR, generate roughly 45 % of global sales due to their proven durability, precise deployment, and extensive clinician familiarity. Self‑expanding platforms, which rely on nitinol frames, capture about 40 % of the market; they are favoured for anatomies requiring conformability, such as bicuspid aortic roots and mitral annuli, and their broader sizing options support higher procedural success in complex cases. Mechanically expandable valves, a nascent class using controlled radial force mechanisms, hold a modest 5 % share but exhibit a higher growth trajectory as manufacturers target low‑risk patients and seek to reduce paravalvular leak. The remaining 10 % reflects hybrid or next‑generation devices under clinical investigation. The relative weight of each type directly influences manufacturing investment, supply‑chain logistics, and reimbursement coding, thereby determining the aggregate market valuation.
