Macroreentrant Atrial Flutter Around a Common Atrioventricular Canal in an Infant with Complicated Congenital Heart Anomaly

SATOMI, K., et al.: Macroreentrant Atrial Flutter Around a Common Atrioventricular Canal in an Infant with Complicated Congenital Heart Anomaly. This report describes a 2‐year‐old male infant after repair of complicated congenital heart anomalies including common atrioventricular canal (CAVC), in which macroreentrant atrial flutter around the CAVC was demonstrated by electroanatomic mapping (CARTO) using a single catheter. Radiofrequency catheter ablation at the isthmus between the CAVC and the inferior vena cava eliminated the atrial flutter successfully.
