During EPS, 12 patients had inducible arrhythmias. Atrial tachycardia was confirmed in three, atrioventricular re\u2010entry tachycardia via manifest accessory pathway (AP) in three, and via concealed AP in one case. Atrioventricular nodal re\u2010entry tachycardia was confirmed in three and sustained monomorphic ventricular tachycardia in two cases. Eleven radiofrequency ablation (84.6%) and two cryoablation (15.4%) were performed. The electroanatomical mapping system was used in all cases. Transseptal puncture was performed in two cases (15.4%) due to left lateral APs. The mean procedure time was 76.0\u00b133.0\u2009minutes. All procedures were performed without fluoroscopy. No complications occurred. During the follow\u2010up, arrhythmia\u2010free survival was achieved in all cases, but in two patients, we used antiarrhythmic drugs (AADs) to achieve it. APGAR score was within the normal range in all cases [median (interquartile range),\u00a09.0\/10.0 (9.0\u201310.0\/9.3\u201310.0)].<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Zero\u2010fluoroscopic catheter ablation was an effective and safe treatment option for our 13 pregnant patients.
