DiamondTemp and Ensite X: Combination of Two New Technologies in a Persistent AF Ablation Case.

Due to the still relatively high recurrence rate after atrial fibrillation (AF) ablation procedure, new tools and strategies to improve postablation freedom from AF are necessary. Recently, the new EnSite X EP cardiac mapping system has received the FDA authorization for its use. DiamondTemp™ is a new radiofrequency (RF) catheter commercialized by Medtronic company with accreditation for pulmonary veins isolation (PVI). The efficacy of this catheter in paroxysmal AF was confirmed by a recent publication (DIAMOND-AF). Currently, a new study is being carried out to validate the usefulness of this catheter in persistent AF: The DIAMOND-AF II. It seems interesting to describe and illustrate the combination of these two new technologies through a case report on persistent AF ablation. [ABSTRACT FROM AUTHOR]
