This report documents a rare familial occurrence of AVNRT in a mother and son, both successfully treated with slow pathway ablation.
Supports ablation in rare familial AVNRT cases; leaves open heritability and screening implications.
Atrioventricular nodal reentrant tachycardia (AVNRT), caused by a reentry circuit involving fast and slow atrioventricular nodal pathways, is one of the most common types of paroxysmal supraventricular tachycardias. While familial Wolff-Parkinson-White syndrome has been well recognized, familial AVNRT has been rarely reported. We report a familial occurrence of AVNRT in a mother and her son, who were symptomatic and successfully treated with radiofrequency catheter ablation of slow pathway.
