BACKGROUND There are limited data regarding factors associated with spontaneous left ventricular reverse remodeling (S-LVRR) among mildly symptomatic heart failure (HF) patients and its prognostic implications on clinical outcomes. METHODS AND RESULTS Best subsets logistic regression analysis was used to identify factors associated with S-LVRR (defined as ≥15% reduction in left ventricular en...
INTRODUCTION AND OBJECTIVES The frequent occurrence of ventricular tachycardia can be a serious problem for patients with an implantable defibrillator, and may necessitate adjuvant antiarrhythmic therapy or radiofrequency catheter ablation. We analyzed the long-term results obtained with this latter therapy in patients suffering from frequent or continuous ventricular tachycardia. PATIENTS AN...
INTRODUCTION AND OBJECTIVES To summarize the findings of the Spanish Implantable Cardioverter-defibrillator Registry for 2012 compiled by the Electrophysiology and Arrhythmias Section of the Spanish Society of Cardiology. METHODS Prospective data recorded voluntarily on single-page questionnaires were sent to the Spanish Society of Cardiology by each implantation team. RESULTS Overall, 4216...
BACKGROUND Atrial fibrillation has a high incidence in patients wearing an implantable cardioverter defibrillator for ventricular tachyarrhythmias and may lead to palpitations, heart failure, angina, stroke and inappropriate defibrillator discharge. The aim of the study was to evaluate the efficacy of a dual chamber defibrillator with atrial antitachycardia functions in treating spontaneous atr...
The correct rate of implantation for implantable cardioverter defibrillator (ICD) and CRT-D devices is not known, but practice surveys suggest persistent under-utilization of these treatments on both sides of the Atlantic. Although recent clinical trial results and the implementation of current guidelines appear to have encouraged a growth of the rate of implantation in most countries, there re...
BACKGROUND Relative wall thickness (RWT), defined as 2 times posterior wall thickness divided by the left ventricular (LV) diastolic diameter, is a measure of LV geometry and may be a marker for adverse events in patients with LV dysfunction. OBJECTIVES The aim of this study was to investigate the relationship between RWT and the risk for ventricular tachyarrhythmia (VA) in patients enrolled ...
