A case of fetal intrauterine tachycardia with further catamnestic observation of a child with WPW syndrome for 10 years

The article describes a clinical case of a child with a common cardiac problem — Wolff-Parkinson-White syndrome (WPW), which often debuts with attacks of achycardie paroxystique AV-receveuse (PAVRT) already in utero and recurs in the postnatal period. It is a well-known fact that fetal tachyarrhythmias can cause not only non-immune hydrops as a symptom of heart failure, but also cause antenatal fetal death. The anatomical and physiological basis of Wolff-Parkinson-White syndrome are additional atrioventricular connections, which can conduct impulses from the atria to the ventricles, causing their pre-excitation. We present a clinical observation of a child with an intermittent type of WPW syndrome. The attacks manifested in utero. However, after the early neonatal period, paroxysms of tachycardia did not bother the patient for a long time. At an older age, the method of choice is RFA, after which attacks of PAVRT most often do not recur. This clinical case demonstrates the need for dynamic observation of patients with fetal tachycardia detected in utero, since attacks can recur at any age. The role of parents in recognizing the clinical manifestations of an attack of paroxysmal tachycardia for timely termination of the paroxysm is also important.
