Pulmonary artery-VAs are an important subset of VA originating from the outflow tract. They have a wider baseline QRS duration compared to RVOT-VAs. Presence of a prepotential aids in the identification of a successful ablation site. Mapping utilizing the reversed U method can help in localization and successful ablation of PA-VAs.
