Why the study?
Does catheter ablation via the pulmonary artery approach eliminate refractory atrial tachycardia originating from the left atrial roof in a patient with prior AF ablation?

Ablation via the pulmonary artery approach may be an effective alternative for eliminating atrial tachycardia originating from the left atrial roof when standard ablation fails.
No takes yet. Share an insight, caveat, or question.
May support pulmonary artery ablation for refractory left atrial roof tachycardia after failed endocardial attempts; hypothesis-generating and requires prospective validation.
