CathWorks is developing an image-based functional flow reserve (FFR) measurement during coronary catheterization, replacing the pressure-wire based, drug-induced measurement currently performed. CathWorks angiogram-based FFR (FFRangio) has met the need for a less invasive FFR assessment tool, to improve real-time functional assessment leading to treatment decisions, and to make coronary catheterization procedures safer, shorter, more accurate and comprehensive.
