Introduction: Arrhythmias can take place in any period of pregnancy. In addition, the incidence of life-threatening ventricular arrhythmias in a pregnant woman without the organic pathology of the heart is rare. Interventional treatment should be carried out in cases of severe arrhythmias and drug resistance. The radiation exposure during ablation carries a potentially harmful effect on the mother and fetus although data on the zero-fluoroscopy ablation of arrhythmias in pregnant women is limited.
Case Presentation:A 26-year-old female without structural heart disease at the gestation period of 26-28 weeks was admitted to a hospital due to severe symptoms of ventricular tachycardia (VT) and premature ventricular contractions. In this regard, the conservative therapy of ?-blockers was ineffective and accompanied by a decrease in blood pressure to 60/40 mm Hg.
Results: An intracardiac electrophysiological study and non-fluoroscopic catheter ablation were carried out considering the drug refractory and severe symptoms of VT. The ablation of the arrhythmia substrate was successfully performed using the Carto 3 System without fluoroscopy. Based on the results, the procedure was not associated with any maternal or fetal complications.
Conclusions: In general, the non-fluoroscopic catheter ablation guided by electro-anatomical mapping and navigation systems is safe and applicable in the treatment of pregnant women with severe types of arrhythmias.
