Left ventricular (LV) scar on late gadolinium enhancement (LGE) cardiac magnetic resonance has been correlated with life-threatening arrhythmic events in patients apparently idiopathic arrhythmias (VAs). We investigated the prognostic significance of a specific LV-LGE phenotype characterized by ringlike pattern fibrosis.A total 686 nonsustained VA underwent contrast-enhanced resonance. A LV was defined as subepicardial/midmyocardial LGE involving at least 3 contiguous segments same...
Implantable cardioverter defibrillators (ICDs) improve survival in patients at risk for cardiac arrest, but are associated with intravascular lead-related complications. The subcutaneous ICD (S-ICD), no components, was developed to minimize complications.To assess key performance measures related delivery of therapy, including inappropriate shocks (delivered absence life-threatening arrhythmia) and failed (which did not terminate ventricular arrhythmia).Randomized, multicenter trial....
The optimal approach to repeat catheter ablation for recurrent paroxysmal atrial fibrillation (PAF) is unknown. Consecutive patients undergoing PAF were studied. A six-step was used in all cases: re-isolation of reconnected pulmonary veins (PVs), left low voltage areas (LVAs), targeted clinical or inducible flutter/tachycardia, non-PV trigger ablation, supraventricular tachycardia, and additional empiric based on operator judgment. primary study outcome arrhythmia-free survival at 1-year....
Ablation of outflow tract ventricular arrhythmias may be limited by a deep intramural location the arrhythmogenic source. This study evaluates acute and long-term outcomes patients undergoing ablation premature complexes (PVCs).This multicenter series included with structurally normal heart or nonischemic cardiomyopathy PVCs defined by: (a) ≥ 2 following criteria: (1) earliest endocardial epicardial activation < 20ms pre-QRS; (2) Similar in different chambers; (3) no/transient PVC...
Abstract Background The effectiveness, safety, and pulmonary vein (PV) reconnection patterns of point‐by‐point high‐power, short‐duration (HPSD) ablation relative to conventional force‐time integral (FTI)‐guided strategies for atrial fibrillation (AF) are unknown. Objectives To compare 1‐year freedom from arrhythmia (AA), complication rates, procedural times, PV with HPSD AF versus an FTI‐guided low‐power, long‐duration (LPLD) strategy. Methods We compared consecutive patients undergoing a...
Abstract Introduction Fluoroscopy use during catheter ablation procedures increases the cumulative lifetime radiation exposure of patients and operators, potentially leading to a higher risk cancer radiation‐related injuries. Nonfluoroscopic (NFA) has been described for supraventricular tachycardia, typical atrial flutter, paroxysmal fibrillation (AF), outflow‐tract ventricular tachycardia (VT). Complete transition NFA more complex arrhythmias, including persistent AF, left (LA) structural...
Recurrent atrial fibrillation (AF) commonly occurs after catheter ablation and is associated with patient morbidity health care costs.
Patients with inherited arrhythmia syndromes are at an increased risk of sudden cardiac death (SCD). Specialized clinics were founded to optimize management and prevention SCD in this population. However, the clinical effectiveness these has never been evaluated.Clinical outcome data patients referred a specialized clinic between 2005 2014 for possible primary electric syndrome or arrhythmogenic right ventricular cardiomyopathy analyzed. Of 720 evaluated, 278 received definite probable...
