The Coronary Flow Meter segmentation by application distinguishes three primary usage categories that collectively shape the market’s revenue profile. Diagnostic applications, which involve physiological assessment of coronary artery disease during cardiac catheterisation, represent the largest share, accounting for roughly 55 % of total sales. This dominance is driven by the high volume of elective angiographies and the growing clinical emphasis on fractional flow reserve (FFR)–guided decision‑making. The Interventional segment, contributing about 35 % of the market, includes flow‑meter integration with percutaneous coronary interventions (PCI) to optimise stent deployment and post‑procedure verification. Although procedural frequency is lower than diagnostic studies, the higher unit price of combined device kits elevates its monetary impact. The remaining 10 % pertains to Research usage, where flow meters support pre‑clinical and clinical trials focused on novel pharmacologic agents or device prototypes. While numerically modest, research spend is characterised by premium pricing and recurring consumable purchases, thereby adding a distinct, albeit smaller, layer to overall market size.
