BACKGROUND: Ventricular tachycardia is a rare condition in the fetus and neonate with a paucity of data regarding the management and outcomes.
METHODS: We reviewed the clinical histories, associated CHD and syndromes, diagnostic investigations, management strategies, and outcomes for all fetuses and neonates with ventricular tachycardia encountered between 2005 and 2020.
RESULTS: Five fetal and 8 neonatal cases of ventricular tachycardia were encountered. Two (40%) fetal cases, compared to 5 (62%) neonatal cases had CHD (p = 0.59), and only 1 fetus had cardiomyopathy with findings suggesting restriction before ventricular tachycardia onset. The median age at ventricular tachycardia presentation was 32 (26-37) weeks for fetal and 11 (1-27) days for neonatal cases. Of the fetal cases, 2 were initially treated trans-placentally with propranolol and 2 with amiodarone. Two fetuses (40%) had ventricular tachycardia suppression prenatally that recurred during the neonatal period necessitating propranolol therapy, 2 (40%) had resolution before birth with no postnatal recurrence, and the cardiomyopathy case never achieved full control, developed hydrops and demised. Of the neonatal cases, 4 received intravenous antiarrhythmics on admission: 3 amiodarone and 1 esmolol, and 2 of these were converted to propranolol and 2 to sotalol. Three other neonates initially received propranolol, with 1 discharged on propranolol, 1 on sotalol, and 1 on mexiletine after failed propranolol and sotalol treatment. The 8th neonate was discharged on no medication.
CONCLUSION: Most fetal and neonatal ventricular tachycardia is manageable with pharmacologic therapy. Given its rarity, larger studies are needed to identify optimal management strategies.
