Empiric Pulsed Field Pulmonary Vein Isolation During Atrial Tachycardia Ablation in Adults With Congenital Heart Disease

Empiric Pulsed Field Pulmonary Vein Isolation During Atrial Tachycardia Ablation in Adults With Congenital Heart Disease

This is a prospective, single-arm intervention trial whereby we will test the safety and efficacy of performing pulmonary vein isolation (PVI) using pulsed field ablation (PFA) in adult patients with congenital heart disease (CHD) who are presenting for atrial tachycardia (AT) ablation.

Inclusion Criteria:

• Adult patients (>= 18 years of age) with repaired or unrepaired congenital heart disease and a history of sustained (>30 seconds) AT

Exclusion Criteria:

• History of sustained AF and/or previous catheter or surgical pulmonary vein isolation.
