A 60-year-old male with a history of prior ablation of typical cavotricuspid isthmus-dependent atrial flutter presented to us with recurrent palpitations. The surface 12-lead EKG was consistent with atrial tachycardia, for which an ablation was planned. The patient was found to have multiple marcroreentrant left atrial tachycardias utilizing areas of scar as substrate. Isthmuses of tissue with fractionated electrograms associated with scar were targeted for ablation.

Posterior left atrial wall isolation for treatment of persistent atrial fibrillation during first-time catheter ablation: An updated systematic review and meta-analysis.

Background: Although catheter ablation (CA) by mean of pulmonary vein isolation (PVI) is nowadays the mainstay treatment for atrial fibrillation (AF), its success-rate in persistent AF remains suboptimal. Results from studies evaluating whether adding posterior wall isolation (PWI) to PVI can increase the success-rate of CA in persistent AF have yielded conflicting data. The aim of this meta-analysis was to assess whether PWI plus PVI might be beneficial in patients with persistent AF.

Catheter ablation procedure for symptomatic atrial fibrillation is an established treatment. Cardiac tamponade is one of the several complications associated with atrial fibrillation ablation. We present the case of a 60-year-old male with a past medical history of end-stage renal disease (ESRD) on hemodialysis, hypotension on midodrine, atrial fibrillation status post-ablation a week prior, and a cerebrovascular accident who presented to the emergency department with complaints of weakness, nausea, vomiting, confusion and some syncopal episodes for the past few days.

Ryanodine receptor 2 (RyR2) protein, a calcium ion release channel in the sarcoplasmic reticulum (SR) of myocardial cells, plays a crucial role in regulating cardiac systolic and diastolic functions. Mutations in RyR2 and its dysfunction are implicated in various congenital heart diseases (CHDs). Studies have shown that mutations in the RYR2 gene, which encodes the RyR2 protein, are linked to several cardiac arrhythmias, including catecholaminergic polymorphic ventricular tachycardia (CPVT), long QT syndrome (LQTS), calcium release deficiency syndrome (CRDS), and atrial fibrillation (AF).

Background: Junctional rhythm (JR) frequently occurs during radiofrequency (RF) ablation procedures targeting the slow pathway (SP) for atrioventricular nodal re-entrant tachycardia (AVNRT), signaling successful ablation. Two types of JR have been noticed: typical JR as His activation preceding atrial activation, and atypical JR as atrial activation preceding the His activation. Nevertheless, the origin and characteristics of JR remain incompletely defined.
