Spontaneous 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 کاملConjoined Inferior Pulmonary Veins during Pulmonary Vein Isolation: Prevalence and Novel Approach for Pulmonary Vein Isolation with Cryoballoon.
Cardiac resynchronization therapy is an established treatment modality in heart failure. Though non-response is a serious issue. To address this issue, a good understanding of the electrical activation during left bundle branch block, biventricular, as well as right- and left ventricular pacing is needed. This way by interpreting the 12-lead electrocardiogram, possible reasons for suboptimal tr...
متن کاملElectrophysiological Evaluation of Pulmonary Vein Isolation.
Since the pulmonary veins (PVs) were identified as a major source of AF triggers, ablation strategies targeting the PVs have evolved from focal ablation inside the PVs to wide area circumferential PV isolation (PVI) which at this juncture is the standard approach. Despite the widespread popularity of PVI, a universal definition is lacking. While "entrance block" is a generally accepted endpoint...
