In this study, we reported the transition period experience of the zero\u2010fluoroscopy procedure by an experienced operator and shared our zero\u2010fluoroscopy protocol.<\/jats:p><\/jats:sec><jats:sec><jats:title>Method<\/jats:title><jats:p>A total of consecutive 30 AF ablation cases attempted to be treated without fluoroscopy were investigated. Ten serial cases were grouped as fluoroscopy\u2010guided period, and period 1\u20103 in chronological order. All zero\u2010fluoroscopy attempted cases were assisted with an intracardiac echocardiography device with a three\u2010dimensional electroanatomical system.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Complete zero\u2010fluoroscopy procedure was achieved at the 6th case during the transitional period. During the first period, the total procedure time slightly increased in, but afterward, procedure time was continuously decreased, and it became significantly shorter in the third period than the previous fluoroscopy\u2010guided period. Any additional use of fluoroscopy during the transitional period was mainly for transseptal puncture and diagnostic catheter placement into the coronary sinus. Pulmonary vein isolation was achieved in all patients, and there was one case of hemodynamically insignificant moderate amount pericardial effusion.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>For an experienced operator, complete zero\u2010fluoroscopy AF ablation might be achieved safely and feasibly within 5\u201010 cases. Fluoroscopy equipment backup might be useful during the learning period for beginners in the zero\u2010fluoroscopy
