Why the study?

Does a management protocol based on SVC/AA Doppler investigation improve the rate of conversion to sinus rhythm in fetuses with sustained SVT?

Population

18 fetuses with sustained supraventricular tachycardia (SVT)

Design

Cohort

Implication

Supports Doppler-guided fetal SVT management; hypothesis-generating and requires randomized validation before practice change.

Structured PICO

Does a management protocol based on SVC/AA Doppler investigation improve the rate of conversion to sinus rhythm in fetuses with sustained SVT?

Population

18 fetuses with sustained supraventricular tachycardia (SVT)

Intervention

Management protocol based on prior identification of the underlying mechanism using superior vena cava/ascending aorta (SVC/AA) Doppler investigation to guide antiarrhythmic therapy (e.g., digoxin, sotalol, amiodarone)

Outcome

Rate of conversion to sinus rhythmsurrogate

A management protocol guided by SVC/AA Doppler to determine the electrophysiological mechanism of fetal SVT is effective in achieving conversion to sinus rhythm.
