Pacemaker treatment for bradyarrhythmia was first approved for national health insurance
coverage in Japan in 1974, and its use rapidly became widespread thereafter …

Background: Advanced generation ablation technologies have been developed to achieve
more effective pulmonary vein isolation (PVI) and minimize arrhythmia recurrence after atrial …

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 …

Background: Catheter ablation is important for treatment of paroxysmal atrial fibrillation
(PAF). Limited animal and human studies suggest a correlation between electrode-tissue …

Background—Contact force (CF) is a major determinant of lesion size and transmurality and
has the potential to improve efficacy of atrial fibrillation ablation. This study sought to …

Aims A challenge of pulmonary vein isolation (PVI) in catheter ablation for paroxysmal atrial
fibrillation (PAF) is electrical reconnection of the PV. EFFICAS I showed correlation between …

Background—Pulmonary vein isolation is the most prevalent approach for catheter ablation
of paroxysmal atrial fibrillation. Long-term success of the procedure is diminished by …

Background—Ablation of atrial fibrillation (AF) is an established treatment option for
symptomatic patients. It is not known whether complete pulmonary vein isolation (PVI) is …
