Arrhythmias may occur during the gestation period. In their study on 136 422 pregnancy-related admissions, Li et al (1) showed a prevalence of 166 in 100 000 admissions due to arrhythmia. The most common types of arrhythmias were associated with the changes in sinus rhythm, namely, 60% of the total arrhythmia occurrence. In addition, premature contractions and supraventricular tachycardia (VT) were reported in 19% and 14% of arrhythmia admissions. However, atrial fibrillation, VT, and atrial-ventricular block were rare accounting for only 1% of all admissions. Normal physiologic changes occurring during pregnancy may trigger arrhythmias due to increases in plasma volume (40%-50%), cardiac output (30%-50%), and the heart rate (30%-50%) during the gestation period. These factors increase the stretching of cardiac chambers, leading to the mismatch of membrane depolarization/refractory period and being the proarrhythmic factors in gestation (2,3). The congenital and structural heart diseases of women and the history of arrhythmias increase the risk of new-onset and recurring arrhythmia episodes during pregnancy (4,5). Nonetheless, the management of arrhythmias in pregnant women has some difficulties and the data of efficiency and safety of the pharmacological therapy of pregnant women is limited. Further, the majority of anti-arrhythmic drugs can cause risks for maternal and fetal side effects (6,7). The catheter ablation of arrhythmias guided by electroanatomic 3D mapping systems has demonstrated similar effects such as conventional fluoroscopy-based ablation methods (8,9). There are some small series and isolated case reports of the successful zero-fluoroscopy catheter ablation of different types of arrhythmias in pregnant women (10-12). The current study aimed to present a case of VT during pregnancy and its treatment with the electroanatomic 3D mapping system.
