The purpose of this study was to examine the feasibility of the Navvus microcatheter coupled to the RXi system (ACIST Medical Systems) to measure lower extremity pre- and post-intervention resting and hyperemic translesional systolic pressure gradients (sTPG) and mean distal to proximal pressure gradients (Pd/Pa).

Since there was a striking paucity of high-level comparative effectiveness evidence on the optimal treatment of patients with CLTI so far, both these landmark trials were awaited with great interest. However, study outcomes are conflicting and therefore worthy of intensive review and in-depth analysis for all medical professions confronted with such patients.
