Why the study?
Cardiac disease is the leading cause of maternal mortality, and frequent cardiac arrhythmias in patients with structural heart disease may cause acute maternal and fetal decompensation requiring immediate management.
Antiarrhythmic therapy during pregnancy should follow the same principles recommended for nonpregnant individuals and often requires multidisciplinary management.
May guide arrhythmia management in pregnancy; leaves open need for dedicated trials.
Cardiac disease is the most common cause of maternal mortality in developed nations. Cardiac arrhythmias are frequent among patients with structural heart disease and may require immediate treatment to prevent hemodynamic instability leading to acute maternal and fetal decompensation. Antiarrhythmic therapy during pregnancy should follow the same principles recommended for nonpregnant individuals. Although multidisciplinary management is recommended, obstetricians, and maternal-fetal medicine specialists may sometimes need to emergently recognize and treat rhythm anomalies before support services become available.
