The FAST Trial Registry is a prospective observational cohort study of fetuses with a new diagnosis of atrial flutter (AF) or supraventricular tachycardia (SVT) that is severe enough to consider prenatal treatment (see eligibility criteria below). Aims of the Registry include to establish a large clinical database to determine and compare the efficacy and safety of different prenatal treatment strategies including observation without immediate treatment, transplacental antiarrhythmic fetal treatment and direct fetal treatment from the time of tachycardia diagnosis to death, neonatal hospital discharge or to a maximum of 30 days after birth.

Start dates may differ between countries and research sites. The research team are responsible for keeping the information up-to-date.

OBSERVATIONAL

Intervention Type : OTHER
Intervention Description : Patients with AF or SVT that is significant enough to consider prenatal treatment are eligible for enrollment. Management decisions are made at each patient encounter by the primary physician based on clinical findings and may include: 1) no antiarrhythmic treatment; 2) transplacental antiarrhythmic treatment; 3) direct fetal antiarrhythmic treatment; 4) delivery. Patients enrolled in the FAST Registry will be followed from the time of enrollment until the baby is discharged after birth.
