Ablation Lesion Assessment with MRI [PDF]
, 2023 Late gadolinium enhancement (LGE) MRI is capable of detecting not only native cardiac fibrosis, but also ablation-induced scarring. Thus, it offers the unique opportunity to assess ablation lesions non-invasively. In the atrium, LGE-MRI has been shown to

Journal of interventional cardiac electrophysiology, 2021 Paroxysmal atrial fibrillation (PAF) can be triggered by non-pulmonary vein foci, like the superior vena cava (SVC). The latter is correlated with improved result in terms of freedom from atrial tachycardias (ATs), when electrical isolation of this ...

Spontaneous and induced pulmonary vein tachycardia after pulmonary vein isolation [PDF]
Europace, 2004 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.

The potential role of scar mapping in assessing of paroxysmal atrial fibrillation recurrence after cryoballoon application [PDF]
, 2016 Cryoballoon ablation for atrial fibrillation (AF) has become a frequently used therapy after failure of at least one antiarrhythmic drug. The main target of AF ablation has been durable pulmonary vein isolation.

Mind the gap: quantification of incomplete ablation patterns after pulmonary vein isolation using minimum path search [PDF]
Medical Image Analysis, 51, 1-12, (2018), 2018 Pulmonary vein isolation (PVI) is a common procedure for the treatment of atrial fibrillation (AF). A successful isolation produces a continuous lesion (scar) completely encircling the veins that stops activation waves from propagating to the atrial body.

Outcomes of Pulmonary Vein Isolation in Athletes
JACC: Clinical Electrophysiology, 2020 The aims of this study were to assess outcomes of pulmonary vein isolation (PVI) performed on athletes at a tertiary care center and to characterize its efficacy and physiological effects.The incidence of atrial fibrillation (AF) is increased in highly trained athletes and poses unique management challenges.Athletes were identified through a database ...

Voltage analysis after multi-electrode ablation with duty-cycled bipolar and unipolar radiofrequency energy: a case report [PDF]
, 2009 Pulmonary vein ablation with a single-tip catheter remains long and complex. We describe a typical case of a novel efficient technique with a decapolar ring catheter utilizing alternating unipolar/bipolar radiofrequency energy.
