Does radiofrequency catheter ablation at the non-coronary aortic cusp terminate focal atrial tachycardia originating from this site?
Focal atrial tachycardia can originate from the non-coronary aortic cusp and be successfully and safely treated with radiofrequency catheter ablation.
Supports non-coronary cusp ablation for focal AT in select cases; hypothesis-generating and requires prospective validation.
We describe a patient with frequent episodes of unusual paroxysmal supraventricular tachycardia. During the electrophysiological examination, the tachycardia was easily induced and terminated by atrial pacing. The earliest activation during right atrial activation mapping was located near the atrioventricular node and the His bundle. However, detailed mapping of the aortic root demonstrated that the local activation in the non-coronary aortic cusp preceded the activation at the His bundle region. Radiofrequency catheter ablation at this site terminated the tachycardia with no complications.
