This study has shown, for the first time, the rapid expression of DNA damage-repair processes associated with spinal cord ischemia and subsequent reperfusion.
BackgroundFetal atrial flutter (AF), accounting for 30% of all fetal tachyarrhythmias, predominantly (over 80%) manifests as a 2:1 atrioventricular conduction. Swift referral and timely intervention become imperative in instances of severe persistent arrhythmia.Case PresentationWe discuss the case of a 32‐year‐old multiparous Chinese woman, at 30+2 weeks of gestation, wherein an ultrasonographic examination revealed persistent fetal AF (atrial rate ranging from 219 to 445 beats/min and ventricular rate from 219 to 228 beats/min, with a 2:1 or 1:1 down transmission) and minor ascites. Despite the maternal ingestion of digoxin and sotalol, the fetal heart rhythm remained uncorrected. Following this, at 32+3 weeks of gestation, an intramuscular injection of cedilanid, guided by ultrasound, was administered to the fetus. Postoperatively, the fetal ventricular rate demonstrated a decline after 6 days, and the ascites resolved. Subsequently, at 33+3 weeks, a cesarean section was necessitated due to maternal intolerance to the medication, resulting in the delivery of the infant. Remarkably, the infant's cardiac rhythm spontaneously converted to sinus rhythm within 5 min of birth. A follow‐up conducted 1 year postpartum revealed no recurrence of AF.ConclusionsThis case illustrates that in the event of transplacental drug treatment failure, intrauterine therapeutic intervention should be considered. Moreover, it highlights the encouraging prognosis associated with fetal AF, as the cardiac rhythm spontaneously reverted to sinus rhythm postbirth in this instance.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
