Case ReportsAblating the Posterior Heart: Cardioesophageal Fistula Complicating Radiofrequency Ablation in the Coronary Sinus.
Cardioesophageal fistulas (CEFs) are uncommon but life-threatening complications of radiofrequency (RF) catheter ablation of atrial fibrillation (AF). They are usually, but not exclusively, related to ablation of the left atrial posterior wall. We report a case of a 73-year-old man that presented with CEF following RF ablation in the coronary sinus, highlighting the importance of esophageal temperature monitoring whenever ablating in the posterior heart.

Case ReportsNew Family With Catecholaminergic Polymorphic Ventricular Tachycardia Linked to the Triadin Gene.
We describe a new family with cathecholaminergic polymorphic ventricular tachycardia (CPVT) linked to the Triadin gene. This is the second report of such a CPVT of autosomal recessive inheritance. Using an NGS panel including 42 genes involved in cardiac sudden death, 2 heterozygous pathogenic mutations (c.613C> T/p. ⋯ Each of the TRDN mutations was inherited from a healthy parent. In this family, genetic studies permit confirmation of the CPVT diagnosis in the 2 affected sibs and permit the early diagnosis of the third asymptomatic child. It also helped guide the therapeutic strategy in this family.

Multicenter Study Comparative StudyAcute and Long-Term Outcomes of Catheter Ablation of Atrial Fibrillation Using the Second-Generation Cryoballoon versus Open-Irrigated Radiofrequency: A Multicenter Experience.
There are limited comparative data on catheter ablation of atrial fibrillation (CAAF) using the second-generation cryoballoon (CB-2) versus point-by-point radiofrequency (RF). This study examines the acute/long-term CAAF outcomes using these 2 strategies. ⋯ In this multicenter, retrospective, nonrandomized study, CAAF using CB-2 coupled with RF as occasionally required was associated with greater freedom from atrial arrhythmias at 12 months following a single procedure without antiarrhythmic therapy when compared to open-irrigated, non-force sensing RF, alone.

Randomized Controlled Trial Multicenter StudyReduction in Inappropriate ICD Therapy in MADIT-RIT Patients Without History of Atrial Tachyarrhythmia.
There are limited data whether history of atrial tachyarrhythmia (AT) modifies the risk of inappropriate ICD therapy, or the efficacy of novel ICD programming to reduce inappropriate ICD therapy events. ⋯ Novel ICD programming with a high-rate cut-off or delayed therapy is equally beneficial to reduce inappropriate ICD therapy in patients with or without prior AT, despite the lower risk of inappropriate ICD therapy in patients without prior AT.

Comparative Study Observational StudyDifference in the Clinical Characteristics of Ventricular Fibrillation Occurrence in the Early Phase of an Acute Myocardial Infarction Between Patients With and Without J Waves.
We recently showed that the presence of J waves increases the risk of ventricular fibrillation (VF) occurrence in the early phase of an acute myocardial infarction (AMI). This study aimed to evaluate the clinical characteristics of VF occurrences in the early phase of an AMI between patients with and without J waves. ⋯ In patients with AMI, those with J waves were more likely to develop VF and less likely to have high-risk clinical characteristics than those without J waves.
