The Japanese Catheter Ablation Registry (JCAR) is a survey of catheter ablation for a variety of arrhythmias. It was planned and carried out by the Japanese Heart Rhythm Society (JHRS)—affiliated committee of catheter ablation. The aim of this registry is to collect data in order to manage the performance and safety of catheter ablation of arrhythmias in Japan. This is the second report on JCAR focusing on subjects who underwent catheter ablation for the treatment of atrial fibrillation (AF). Details of the registry were previously reported. In brief, data of the procedures for catheter ablation, results, complications, and clinical profiles of patients who underwent ablation for any form of arrhythmia from January 2008 to July 2010 were anonymously collected. Until the end of 2010, 88EP centers listed in the Appendix voluntarily submitted data on 96±129 sessions. The total number of session was 8469. The number of arrhythmias treated was 8545. Among these, 2291 cases of AF ablation were included (27.1%). The numbers of patients with paroxysmal AF, persistent AF, and long-lasting persistent AF were 1519, 468, and 304, respectively. Table 1 shows clinical profiles of the patients. Long-lasting persistent AF was associated with longer-term morbidity and decreased left ventricular function. The prevalence of nonischemic cardiomyopathy was greater in those with persistent or long-lasting persistent AF. Pharmacological treatments and their clinical outcome are summarized in Table 2. Subjects with long-lasting persistent AF took fewer antiarrhythmic agents than those with paroxysmal or persistent AF. However, bepridil was more widely used in patients with long-lasting AF. Table 3 compares the prevalence of risk factors for thromboembolism among the 3 types of AF. There was noticeable inter-group variation in the proportion of older patients, history of congestive heart failure, and hypertension. Techniques for pulmonary (PV) isolation and other ablation sites are shown in Table 4. Instruments, RF settings, and AF provocation after the treatment are also given. Because the irrigation catheter system was not approved until July 2009, irrigation catheter usage is not shown. Compared with paroxysmal AF, persistent AF and long-lasting persistent AF required ablation of the left atrium, coronary sinus, or sites with complex fragmented atrial electrogram (CFAE). Pharmacological treatments at discharge are listed in Table 5. We intend to present further observations, such as complications and recurrence of AF, in subsequent reports.
