In most cases, the fetus can be delivered without therapeutic\n                    intervention. Hemodynamic instability and fetal hypoperfusion leading to fetal\n                    harm may occur if persistent episodes of high ventricular rate occur. In these\n                    cases, resolution of the arrhythmia may be advised. Antiarrhythmic drugs can be\n                    used with limitations and great caution in those expecting a child, so catheter\n                    ablation may be a safe and usable alternative. These interventions are\n                    traditionally performed using X-ray, however, due to the effect of ionizing\n                    radiation on fetal development, this would pose a high risk. Zero-fluoroscopic\n                    ablation has been available for several years in cardiac electrophysiology,\n                    which can be used both in the treatment of atrial fibrillation and in other\n                    arrhythmias. The procedure which we used in pregnant women is presented in two\n                    cases. We also managed to completely eliminate the use of X-ray during the\n                    interventions presented in this article. In the first case, a 23-week-old gravid\n                    patient underwent electrophysiological examination for recurrent paroxysmal\n                    supraventricular tachycardia. In the electrophysiological study,\n                    atrioventricular nodal reentry tachycardia was confirmed and successfully\n                    ablated. In our second case study, we present a catheter ablation for\n                    anteroseptal accessory pathway. Three-dimensional mapping system (supplemented\n                    with intracardiac ultrasound, if necessary), in the case of significant\n                    arrhythmia, is a safe and effective alternative where X-rays, which poses a risk\n                    to the mother and\/or the fetus, cannot be used during pregnancy.
