Does diffuse irrigation result in improved radiofrequency catheter ablation? A prospective randomized study of right atrial typical flutter ablation

摘要

Aims Recent developments of open irrigated catheters have sought to create uniform cooling of the entire ablating electrode. The aim of this randomized study was to assess whether the diffuse irrigation of the Coolflex (R) (CF) catheter results in improved short-term procedural benefits in patients undergoing ablation of right atrial typical flutter.
