Recently, the feasibility and effectiveness of zero\u2010fluoroscopy ablation have been reported. However, studies on the outcomes of zero\u2010fluoroscopy ablation in Japan remain limited. This study investigated the outcomes of zero\u2010fluoroscopy ablation for cardiac arrhythmias at a Japanese institute.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods and Results<\/jats:title><jats:p>We present a retrospective analysis of the safety, efficacy, and feasibility data from 221 consecutive patients who underwent zero\u2010fluoroscopy ablation. Of these patients, 181 had atrial fibrillation, 17 had paroxysmal supraventricular tachycardia, 13 had atrial tachycardia, 6 had ventricular tachycardia, and 4 had ventricular premature contractions. We performed zero\u2010fluoroscopy ablation using three\u2010dimensional electro\u2010anatomical mapping systems and intracardiac echocardiography imaging. Ultrasound\u2010guided sheath insertion was performed on all cases. Our experience includes exclusively endocardial cardiac ablations. The mean follow\u2010up was 24\u00a0months. The recurrence rates were 25.4% for atrial fibrillation, 5.9% for paroxysmal supraventricular tachycardia, 15.4% for atrial tachycardia, 33.3% for ventricular tachycardia, and 25% for ventricular premature contraction. Complications occurred in two patients (0.9%), and there was no occurrence of death. A fluoroscopic guide was used in three cases for the confirmation of vascular access (one case) and for complications (two cases).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Zero\u2010fluoroscopy ablation was routinely performed without compromising on safety and efficacy.
