Key result
Radiofrequency catheter ablation was successfully performed in 3 pregnant women with drug-refractory supraventricular tachycardias at 29-30 weeks' gestation, resulting in normal newborn Apgar scores.

Does radiofrequency catheter ablation safely treat drug-refractory maternal supraventricular tachycardias in advanced pregnancy?
Radiofrequency catheter ablation can be successfully and safely performed in advanced pregnancy for drug-refractory supraventricular tachycardias.
Supports feasibility of ablation for refractory SVT at 29-30 weeks but should not change practice; leaves open need for prospective safety data.
BACKGROUND Treatment of maternal tachyarrhythmias in pregnancy is a major clinical issue. Pharmacological treatment raises important concerns regarding partial efficacy and side effects. Radiofrequency ablation of arrhythmogenic substrate has rarely been performed during pregnancy because of the fetal risks related to x-ray exposure and potential fetomaternal procedural complications. CASES Three women affected by supraventricular tachycardias refractory to pharmacological therapy underwent successful radiofrequency catheter ablation at 29 to 30 weeks' pregnancy. All patients had cesarean delivery of newborns with normal Apgar scores. CONCLUSION Radiofrequency catheter ablation is an effective treatment of drug refractory maternal supraventricular tachycardias in advanced pregnancy. Further studies are required to establish its long-term fetal safety.

Bombelli et al. (2003) conducted a case report in Drug refractory maternal supraventricular tachycardias (n=3). Radiofrequency catheter ablation was evaluated on Procedural success and newborn Apgar scores. Radiofrequency catheter ablation was successfully performed in 3 pregnant women with drug-refractory supraventricular tachycardias at 29-30 weeks' gestation, resulting in normal newborn Apgar scores.
