Coherent mapping of atrial tachycardias in patients with congenital heart disease
Authors' conclusion
Mapping of AT in patients with CHD using the PENTARAY™ mapping catheter and the CM algorithm led to excellent acute success. All ATs were possible to map and no complications related to the PENTARAY™ mapping catheter were observed.
