Background: Imaging techniques have shown the association between left atrial adipose tissue (LAAT) volume and atrial fibrillation (AF) risk.
Purpose: To analyze 1) adipokines in peripheral and atrial plasma from patients undergoing AF ablation; 2) its association with LAAT volume measured by multislice CT and 3) its predictive value for AF recurrence.
Methods: Seventy consecutive patients undergoing AF catheter ablation were screened.
Objectives: The goal of this study was to describe short- and long-term outcomes in all patients referred for inappropriate sinus tachycardia ablation, along with the potential complications of the intervention.
Background: Sinus node (SN) ablation/modification has been proposed for patients refractory to pharmacological therapy. However, available data derive from limited series.
Comparative Evaluation of Four Risk Scores for Predicting Mortality in Patients With Implantable Cardioverter-defibrillator for Primary Prevention.
Rev Esp Cardiol (Engl Ed)
November 2016
Introduction And Objectives: Several clinical risk scores have been developed to identify patients at high risk of all-cause mortality despite implantation of an implantable cardioverter-defibrillator. We aimed to examine and compare the predictive capacity of 4 simple scoring systems (MADIT-II, FADES, PACE and SHOCKED) for predicting mortality after defibrillator implantation for primary prevention of sudden cardiac death in a Mediterranean country.
Methods: A multicenter retrospective study was performed in 15 Spanish hospitals.
Comparison between CHA2DS2-VASc and the new R2CHADS2 and ATRIA scores at predicting thromboembolic event in non-anticoagulated and anticoagulated patients with non-valvular atrial fibrillation.
BMC Cardiovasc Disord
November 2015
Background: Accurate risk stratification is considered the first and most important step in the management of patients with non-valvular atrial fibrillation (NVAF). We compared the performance of the widely used CHA2DS2-VASc and the recently developed R2CHADS2 and ATRIA scores, for predicting thromboembolic (TE) event in either non-anticoagulated or anticoagulated patients with NVAF.
Methods: The non-anticoagulated cohort was comprised of 154 patients, whereas 911 patients formed the cohort of patients on vitamin-K-antagonist.
Background: Isolated cases of monomorphic ventricular tachycardia (MVT) in patients with Brugada syndrome (BrS) have been reported.
Objective: We aimed to describe the incidence and characteristics of MVT in a cohort of patients with BrS who had received an implantable cardioverter-defibrillator (ICD).
Methods: Data from 834 patients with BrS implanted with an ICD in 15 tertiary hospitals between 1993 and 2014 were included.
Renal function assessment in atrial fibrillation: Usefulness of chronic kidney disease epidemiology collaboration vs re-expressed 4 variable modification of diet in renal disease.
World J Cardiol
October 2015
Aim: To compare the performance of the re-expressed Modification of Diet in Renal Disease equation vs the new Chronic Kidney Disease Epidemiology Collaboration equation in patients with non-valvular atrial fibrillation.
Methods: We studied 911 consecutive patients with non-valvular atrial fibrillation on vitamin-K antagonist. The performance of the re-expressed Modification of Diet in Renal Disease equation vs the new Chronic Kidney Disease Epidemiology Collaboration equation in patients with non-valvular atrial fibrillation with respect to either a composite endpoint of major bleeding, thromboembolic events and all-cause mortality or each individual component of the composite endpoint was assessed using continuous and categorical ≥ 60, 59-30, and < 30 mL/min per 1.
Risk of pacemaker implantation after uneventful successful cavotricuspid isthmus radiofrequency ablation in patients with common atrial flutter.
Int J Cardiol
January 2016
Introduction: Little is known about the risk of pacemaker implantation after common atrial flutter ablation in the long-term.
Methods: We retrospectively reviewed the electrophysiology laboratory database at two Spanish University Hospitals from 1998 to 2012 to identify patients who had undergone successful ablation for cavotricuspid dependent atrial flutter. Cox regression analysis was used to examine the risk of pacemaker implantation.
Article Synopsis
- Atrial fibrillation (AF) is a common heart condition that can't always be treated effectively with rhythm control, leaving many patients relying on rate control methods.
- Some patients experience symptoms and risks related to ineffective pharmacological rate control, such as heart failure.
- Catheter ablation of the atrioventricular junction, followed by a permanent pacemaker, can offer reliable rate control, especially for patients with heart failure and reduced function.
Introduction: Little is known about the prevalence of electrical storm, baseline characteristics and mortality implications of patients with implantable cardioverter defibrillator in primary prevention versus those patients without electrical storm. We sought to assess the prevalence, baseline risk profile and survival significance of electrical storm in patients with implantable defibrillator for primary prevention.
Methods: Retrospective multicenter study performed in 15 Spanish hospitals.
Background: ICDs have been demonstrated to be highly effective in the primary prevention of sudden death, but inappropriate shocks (IS) occur frequently and represent one of the most important adverse effects of ICDs. The aim of this study was to analyze IS and identify the clinical predictors and prognostic implications of ISs in a real-world primary prevention ICD population.
Methods: This multicenter retrospective study was performed in 13 centers with experience in the field of ICD implantation (at least 30 per year) and ICD follow-up in Spain.
Introduction: At the present time there is still concern regarding the long-term deleterious effects of right ventricular apical pacing in patients referred for auriculoventricular node ablation (AVNA). Furthermore, scarce information is available regarding differences in the follow up according to the baseline cardiopathy and predictors associated with a worse outcome.
Methods: 104 consecutives patients referred for AVNA were retrospectively analyzed.
