GP mapping and ablation and AF ablation
In all patients, successful access to LA and performance of 3D electroanatomic mapping was possible, with identification of PV ostia and GP specified anatomic location sites. Completion of the lesion subset prespecified to ablate right GP was undertook in all patients, with approaches from the left and right atria. In the four patients with documented paroxysmal atrial fibrillation, PV isolation was done and with achievement of bidirectional block in all patients.
