Solid tip cryoablation is a feasible and successful approach for treating focal atrial tachycardia originating from the anatomically complex right atrial appendage.
Adds to limited evidence for cryoablation in right atrial appendage tachycardia; requires validation before changing practice.
The right atrial appendage can be the origin of focal atrial tachycardias. Their ablation can be challenging owing to the complexity of the appendage anatomy. To our knowledge, we describe the first successful solid tip cryoablation of a focal tachycardia within the right atrial appendage in a patient presenting with tachycardia-induced cardiomyopathy.
