Effectiveness and Safety of Electrical Cardioversion and Catheter Ablation in Pregnant Patients

Background

Arrhythmias during pregnancy can lead to significant maternal and fetal complications, including cardiovascular instability and fetal distress. Despite guideline recommendations, the use of electrical cardioversion and catheter ablation remains limited. Understanding the efficacy and safety of these interventions is crucial for managing pregnancy-associated arrhythmias.

Data Highlights

ProcedureSuccess RatePreterm DeliveryMaternal-Fetal Mortality
Electrical Cardioversion89.7%5 cases2 cases
Catheter Ablation97.5%2 cases0 cases

Key Findings

  • Electrical cardioversion has a success rate of 89.7% in pregnant patients.
  • Catheter ablation has a higher success rate of 97.5% during pregnancy.
  • Among patients undergoing electrical cardioversion, there were 5 cases of preterm delivery and 2 cases of maternal-fetal mortality.
  • The catheter ablation group reported 2 cases of preterm delivery with no maternal-fetal mortality.
  • Atrial fibrillation was the most common arrhythmia in the electrical cardioversion group.
  • AVNRT was the predominant arrhythmia in the catheter ablation cohort.

Clinical Implications

The findings indicate the need for further evaluation of electrical cardioversion and catheter ablation in pregnant patients with arrhythmias.

Conclusion

Electrical cardioversion and catheter ablation have been reported in the literature as treatment options for managing arrhythmias during pregnancy.
