Efficacy and safety of electrical cardioversion and catheter ablation during pregnancy: a case review and literature analysis

To evaluate the effectiveness and safety of electrical cardioversion and catheter ablation in pregnant patients with arrhythmias.

Case Presentation: A 24-year-old primigravida with recurrent supraventricular tachycardia underwent catheter ablation and later experienced further arrhythmia, leading to cesarean delivery.
Systematic Review: A systematic review of studies on electrical cardioversion and catheter ablation during pregnancy was conducted, assessing efficacy and safety.

The evidence suggests that both electrical cardioversion and catheter ablation may be treatment options for managing arrhythmias during pregnancy.
