Abstract

Catheter ablation of cardiac arrhythmias in pregnancy with limited fluoroscopy

Objective: This study sought to evaluate the feasibility and safety of catheter ablation in pregnancy with limited fluoroscopy.

Method: A case-control retrospective study.

Results: Ten patients with tachycardia in pregnancy (age 26, 30 ± 4, 52 years; gestational age 26, 90 ± 2, 88 weeks) successfully underwent radiofrequency catheter ablation procedures with limited fluoroscopy. Type of tachycardia consisted of 2 patients with atrial tachycardia; 2 patients with ventricular tachycardia; 4 patients with atrioventricular reentrant tachycardia; 2 patients with atrioventricular nodal reentrant tachycardia. Procedure time, fluoroscopy time, total dose area product were 66, 50 ± 19, 86 minutes; 118, 80 ± 64, 38 seconds; 0, 73 ± 0, 64 Gy-cm2 respectively. There were not any complications during and after procedures. All pregnancy normally delivered healthy babies.

Conclusion: Catheter ablation with limited fluoroscopy can be performed safely and with good outcomes in pregnancy.
