Case series of catheter-based arrhythmia ablation in 13 pregnant women.

Background: Catheter ablation is a rarely used procedure to treat arrhythmias during pregnancy.

Hypothesis: In the case of maternal arrhythmia during pregnancy, zero-fluoroscopic catheter ablation is preferable to medical treatment.

Methods: Between April 2014 and September 2021, we examined the demographic data, procedural parameters, and fetal and maternal outcomes in pregnant women undergoing ablation at the Gottsegen National Cardiovascular Center and University of Pécs Medical School, Heart Institute.
