Adequate catheter-tissue contact facilitates efficient heat energy transfer to target tissue.
Tissue contact is thus critical to achieving lesion transmurality and success of …

In the last three decades, ablation of atrial fibrillation (AF) has become an evidence-based
safe and efficacious treatment for managing the most common cardiac arrhythmia. In 2007 …

Background Many centers use radiofrequency (RF) energy at 25–35 W for 30–60 seconds.
There is a safety concern about using higher power, especially on the posterior wall …

Aims Force–Time Integral (FTI) is commonly used as a marker of ablation lesion quality
during pulmonary vein isolation (PVI), but does not incorporate power. Ablation Index (AI) is …

Background Radiofrequency high‐power ablation appears to be a novel concept for atrial
fibrillation (AF). The ablation index (AI) value has been associated with durability of …

Purpose The optimal radiofrequency (RF) power and lesion duration using contact force
(CF) sensing catheters for atrial fibrillation (AF) ablation are unknown. We evaluate 50 W RF …

This manuscript reviews the literature for all in silico, ex vivo, in vitro, in vivo and clinical
studies of high‐power short‐duration (HPSD) radiofrequency (RF) ablations. It reviews the …

Introduction Successful catheter ablation is limited by both poor spatial resolution of
abnormal local signals and inability to deliver an effective lesion due to poor tissue contact …

More than three decades have passed since utilization of radiofrequency (RF) ablation in
the treatment of cardiac arrhythmias. Although several limitations and challenges still exist …

Aims Radiofrequency ablation creates irreversible cardiac damage through resistive heating
and this temperature change results in a generator impedance drop. Evaluation of a novel …
