Key result
Short ventriculo-atrial time interval in fetal supraventricular tachycardia was associated with 100% survival and digoxin responsiveness, compared to 75% survival and digoxin failure in long VA types.
Why the study?
Does ventriculo-atrial time interval measured on M mode echocardiography predict treatment response and prognosis in fetuses with supraventricular tachycardia?
Observational (n=23)
Does ventriculo-atrial time interval measured on M mode echocardiography predict treatment response and prognosis in fetuses with supraventricular tachycardia?
Absolute Event Rate: 100% vs 75%
Fetal M mode echocardiography can distinguish short from long VA supraventricular tachycardia, which is useful for optimizing management as digoxin appears ineffective in the long VA type.

May aid VA interval classification of fetal SVT on M-mode; leaves open impact on management and outcomes in prospective studies.
Jaeggi et al. (1998) conducted an observational in fetal supraventricular tachycardia (n=23). Short ventriculo-atrial (VA) time interval vs. Long ventriculo-atrial (VA) time interval was evaluated on Survival. Short ventriculo-atrial time interval in fetal supraventricular tachycardia was associated with 100% survival and digoxin responsiveness, compared to 75% survival and digoxin failure in long VA types.
