DIGOXIN AND AMIODARON IN FETAL SUSTAINED SUPRAVENTRICULAR TACHYCARDIA AND NONIMMUNE HYDROPS

SUMMARY. Supraventricular tachycardia is the most common and clinically significant form of sustained fetal tachyar-rhythmia in pregnancy; depending on duration and high rate variability heart failure and nonimmune hydrops may de-velop which are associated with a high incidence of perinatal mortality. Doppler/echo diagnosis is usually accidental during second and third trimester of pregnancy. Therapeutic goals are cardioconversion to sinus rhythm and recovery of heart failure. We present a case of fetal supraventricualr tachycardia diagnosed at 29 weeks of gestation with nonimmune hydrops. Treatment with digoxin and amiodarone was successful. The heart rate restored to sinus rhythm and nonim-mune hydrops resolved within three weeks of treatment. Therapy with two drugs that act synergistically may be more efficient than monotherapy in blocking likely atrio-ventricular reentry mechanism by accessory pathway in sustained supraventricular tachycardia, thus allowing resolution of hydrops with favorable management outcome.
