Emergency zero-fluoroscopy catheter ablation for refractory ventricular tachycardia in third-trimester pregnancy: a case report.

ABSTRACT:

Background

The incidence of symptomatic arrhythmias during pregnancy has markedly increased in recent years. Atrial fibrillation/flutter and life-threatening ventricular arrhythmias are of particular concern due to their association with elevated maternal and fetal risks. Cardioversion, antiarrhythmic drugs, or catheter ablation are treatment options for hemodynamically unstable arrhythmias. However, indications of therapeutic options and standardized protocols remain scarce due to the limited shared clinical experiences and evidence.

Case summary

On 17 June 2025, our team managed a 32-week pregnant patient with refractory ventricular tachycardia (VT) following a 16-day treatment course for myocarditis. The arrhythmia was unresponsive to intravenous adenosine. After multidis
