Summary
Our case shows of a rare unidirectional pulmonary vein (PV) exit conduction block during pulmonary vein isolation (PVI) procedure. Following circumferential antral ablations around the right pulmonary veins (RPVs), pacing the PV showed local capture without conducting to atrium. Meanwhile pacing the atrium showed continuous presence of PV potentials. Our case is a unique example of unidirectional block in the unusual direction.
