Contrast injection into the right atrial appendage apex using an external irrigation catheter for focal atrial tachycardia ablation

Focal atrial tachycardias (ATs) originating from the right atrial appendage (RAA) apex are refractory to catheter ablation and can cause tachycardia‐induced cardiomyopathy. After unsuccessful catheter ablation of these ATs, their elimination sometimes requires atrial appendectomy for treatment of ta...

description Focal atrial tachycardias (ATs) originating from the right atrial appendage (RAA) apex are refractory to catheter ablation and can cause tachycardia‐induced cardiomyopathy. After unsuccessful catheter ablation of these ATs, their elimination sometimes requires atrial appendectomy for treatment of tachycardia‐induced cardiomyopathy. This case demonstrates that contrast injection into the RAA apex using an external irrigation catheter can facilitate mapping of such ATs and may provide safe and effective ablation of their sources even in the RAA tip.[Image: see text]
