Saline-Induced Coronary Hyperemia: Mechanisms and Effects on Left Ventricular Function [Cardiac Catheterization]

Conclusions—
Intracoronary infusion of saline at room temperature through a dedicated catheter for coronary thermodilution induces steady-state maximal hyperemia at a flow rate ≥15 mL/min. These findings open new possibilities to measure maximal absolute coronary blood flow and minimal microcirculatory resistance.
