Determinants of Acute and Late Pulmonary Vein Reconnection in Contact Force–Guided Pulmonary Vein Isolation
Catheter-based pulmonary vein isolation (PVI) is associated with a single procedure freedom from atrial fibrillation (AF) in ≈70% of patients with paroxysmal AF. Lack of durability of PVI, a major determinant of AF recurrence, is evidenced by acute PV reconnection at the time of the procedure and late pulmonary vein reconnection (PVR) during followup. The use of contact force (CF)–sensing cathe...
متن کاملSpontaneous and induced pulmonary vein tachycardia after pulmonary vein isolation.
A case is reported of recurrence of paroxysmal atrial fibrillation after pulmonary vein ablation. A second procedure achieved isolation of three pulmonary veins and showed persistence of pulmonary vein tachycardia in one with implications concerning the electrophysiology of atrial fibrillation.
متن کاملLeft atrial-pulmonary vein reentrant tachycardia following pulmonary vein isolation.
Pulmonary vein isolation has become the cornerstone of ablation for atrial fibrillation. However, it is sometimes followed by the development of left atrial macro-reentrant tachycardia. There is evidence to suggest that the myocardial sleeves within the pulmonary veins may be implicated in the mechanism of the tachycardia. Here we present a case of a post-ablation macro-reentrant tachycardia, i...
متن کاملCircumferential pulmonary vein isolation: wait or stop early after initial successful pulmonary vein isolation?
AIMS Circumferential pulmonary vein isolation (PVI) is the current standard of interventional atrial fibrillation (Afib) therapy. However, recurrence rate of Afib varies considerably after ablation between different series and is mainly attributed to the recovery of pulmonary vein (PV) conduction after initial successful PVI. STUDY HYPOTHESIS Waiting longer during the initial PVI procedure an...
متن کاملReduced residual conduction gaps and favourable outcome in contact force-guided circumferential pulmonary vein isolation
AIMS Although contact force (CF)-guided circumferential pulmonary vein isolation (CPVI) for paroxysmal atrial fibrillation (PAF) is useful, AF recurrence at long-term follow-up still remains to be resolved. The purpose of this study was to assess safety and efficacy of CF-guided CPVI and to compare residual conduction gaps during CPVI and long-term outcome between the conventional (non-CF-guide...
