Transplacental treatment of foetal supraventricular tachycardia with triple antiarrhythmic combination to avoid intra-foetal intervention

Abstract

AbstractAlthough a high percentage of foetuses with supraventricular tachycardia respond to single or dual antiarrhythmic therapy, on occasion when there is no response to these combination regimens, direct intra-foetal therapy remains the only choice, albeit such an approach carries a potential risk to the foetus.Data with regard to the safety and efficacy of triple antiarrhythmic combination have not been reported before. Here, we present a foetus with intractable tachycardia in whom arrhythmia termination was successfully achieved with triple oral antiarrhythmic therapy.
