Multicenter Study Observational StudyArrhythmogenic right ventricular dysplasia/cardiomyopathy and cardiac sarcoidosis: distinguishing features when the diagnosis is unclear.
Cardiac sarcoidosis (CS) may show overlap in the clinical presentation with arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVD/C). We sought to investigate patients with CS who were misdiagnosed with ARVD/C and identify clinical features to distinguish these 2 groups. ⋯ The 2010 diagnostic criteria for ARVD/C have limited discrimination in distinguishing between ARVD/C and CS. Despite the overlay in clinical presentation, older age of symptom onset, presence of cardiovascular comorbidities, nonfamilial pattern of disease, PR interval prolongation, high-grade atrioventricular block, significant left ventricular dysfunction, myocardial delayed enhancement of the septum, and mediastinal lymphadenopathy should raise the suspicion for CS.

Multicenter Study Observational StudyPercutaneous left ventricular assist devices in ventricular tachycardia ablation: multicenter experience.
Data on relative safety, efficacy, and role of different percutaneous left ventricular assist devices for hemodynamic support during the ventricular tachycardia (VT) ablation procedure are limited. ⋯ Impella and TandemHeart use in VT ablation facilitates extensive activation mapping of several unstable VTs and requires fewer rescue shocks during the procedure when compared with using IABP.

Multicenter StudyEffects of sex on the incidence of cardiac tamponade after catheter ablation of atrial fibrillation: results from a worldwide survey in 34 943 atrial fibrillation ablation procedures.
Cardiac tamponade is the most dramatic complication observed during atrial fibrillation (AF) ablation and the leading cause of procedure-related mortality. Female sex is a known risk factor for complications during AF ablation; however, it is unknown whether women have a higher risk of tamponade. ⋯ Tamponade during AF ablation procedures is relatively rare. Women have an ≈2-fold higher risk for developing this complication. The risk of tamponade among women decreases substantially in high-volume centers. Surgical backup and acute management skills for treating tamponade are important in centers performing AF ablation.
