5. Study Description

Brief Summary
The study evaluates the use of half-normal saline as an irrigant for open-irrigated catheters during atrial fibrillation ablation. By increasing the efficacy of radiofrequency energy-mediated lesion formation, half-normal saline has the potential to reduce procedural times and improved acute and long-term outcomes.
