Review
Pulmonary vein isolation (PVI) is a well-established treatment for atrial fibrillation (AF); however, studies report suboptimal outcomes in persistent AF. Adjuvant ablation targeting the substrate outside the pulmonary veins has been proposed to improve the success rates of the procedure. In this review, we summarize the current evidence regarding additional ablation over PVI in persistent AF. We describe the different approaches for adjuvant ablation, outcomes, and future perspectives.

Review
In patients with atrial fibrillation refractory to drug therapy and cardioversion, pulmonary vein ablation is an alternative treatment that eradicates arrhythmogenic activity originating in the muscles of the pulmonary veins. While this procedure has a low incidence of significant complications, iatrogenic injuries are possible. Through multimodality pictorial examples utilizing computed tomography, nuclear medicine, fluoroscopy, and chest radiographs, the complications associated with pulmonary vein ablation will be reviewed. Examples of pulmonary vein stenosis, right phrenic nerve injury with associated diaphragmatic paralysis, atrioesophageal fistula, and pericardioesophageal fistula will be illustrated.

Review
Thirty-eight patients had assessment of pulmonary vein occlusion with the dielectric mapping system and injection of saline as an alternative to contrast. Contrast injection was required to ascertain pulmonary vein occlusion in 31.6% (12 of 38) of subjects and 17.4% (27 of 155) of veins. No contrast was required in the last 13 subjects. In this single center study, a novel mapping-guided cryoablation approach appeared to minimize the use of contrast in pulmonary vein isolation for the treatment of atrial fibrillation.

Review
The pulmonary vein has a unique electrophysiological property showing an autonomic electrical activity, and this phenomenon has been further focused on as a source of triggers of atrial fibrillation. The pulmonary vein cardiomyocytes have shorter action potential duration, less negative resting membrane potential, and smaller maximum upstroke velocity than those in the left atrium, whose underlying cellular mechanisms may generate arrhythmogenic substrates such as abnormal automaticity and triggered activity. In diseased conditions including sustained atrial tachycardia or chronic volume overload, its arrhythmogenic profile can be further modified through abbreviation of action potential duration of the pulmonary vein myocardium, which may become a cause of reentry. Recently, antiarrhythmic effects of various drugs have been extensively investigated in isolated pulmonary vein preparations. The present review article highlights the recent advances in our understanding of electrophysiological and pharmacological profiles of the pulmonary vein.

Oesophageal stents allow endoscopic treatment of several oesophageal disorders. Although oesophageal stents are generally safe, early and late adverse events may occur. We present a previously unpublished complication consisting of a pulmonary vein pseudoaneurysm secondary to an oesophageal stent displacement.
