Objective: To evaluate whether the procedural outcome of ablation for AF is associated with quality of life (QOL) measures.

Design, Setting, And Participants: This was a prespecified secondary analysis of the Substrate and Trigger Ablation for Reduction of Atrial Fibrillation-Part II (STAR AF II) prospective randomized clinical trial, which compared 3 strategies for ablation of persistent AF.

Cardiac resynchronization therapy before and after MitraClip implantation: An advantageous upgrading to reduce mitral regurgitation.

MitraClip therapy has been proposed as therapeutic option in selected patients with degenerative or functional mitral regurgitation (FMR), leading to clinical and prognostic benefits. Previous studies demonstrated the safety and the efficacy of MitraClip therapy on symptoms and left ventricular remodeling in cardiac resynchronization therapy (CRT) non-responder patients. We report a case of a CRT non-responder patient treated with MitraClip implantation followed by a new upgrading of the CRT for persistent FMR at the follow-up.

Impact of acute atrial fibrillation termination and prolongation of atrial fibrillation cycle length on the outcome of ablation of persistent atrial fibrillation: A substudy of the STAR AF II trial.

Background: Controversy exists about the impact of acute atrial fibrillation (AF) termination and prolongation of atrial fibrillation cycle length (AFCL) during ablation on long-term procedural outcome.

Objective: The purpose of this study was to analyze the influence of AF termination and AFCL prolongation on freedom from AF in patients from the STAR AF II (Substrate and Trigger Ablation for Reduction of Atrial Fibrillation Trial-Part II) trial.

Methods: Acute changes in AFCL and AF termination were collected during the index procedure of the STAR AF II trial and compared to recurrence of AF at 18 months.

Safety and efficiency of ventricular pacing prevention with an AAI-DDD changeover mode in patients with sinus node disease or atrioventricular block: impact on battery longevity-a sub-study of the ANSWER trial.

Aims: This ANSWER (EvaluAtioN of the SafeR mode in patients With a dual chambER pacemaker indication) sub-study assesses safety and effectiveness of SafeR™ and the impact of ventricular pacing (VP) prevention on anticipated device longevity and replacement rate.

Methods And Results: Patients implanted for atrioventricular block (AVB, n = 310) or sinus node dysfunction (SND, n = 336) were randomly assigned to SafeR (n = 314) or DDD (n = 318) and followed for 36 months. Safety, median VP, estimated device longevity (mean difference, 95% confidence interval [CI]), and anticipated replacement rates were analysed by pacing mode and implant indication.

Approaches to catheter ablation for persistent atrial fibrillation.

Background: Catheter ablation is less successful for persistent atrial fibrillation than for paroxysmal atrial fibrillation. Guidelines suggest that adjuvant substrate modification in addition to pulmonary-vein isolation is required in persistent atrial fibrillation.

Methods: We randomly assigned 589 patients with persistent atrial fibrillation in a 1:4:4 ratio to ablation with pulmonary-vein isolation alone (67 patients), pulmonary-vein isolation plus ablation of electrograms showing complex fractionated activity (263 patients), or pulmonary-vein isolation plus additional linear ablation across the left atrial roof and mitral valve isthmus (259 patients).

Frequent Home Monitoring of ICD Is Effective to Prevent Inappropriate Defibrillator Shock Delivery.

Recently, in the context of telemedicine, telemonitoring services are gaining attention. They are offered, for example, to patients with implantable cardioverter defibrillators (ICDs). A major problem associated with ICD therapy is the occurrence of inappropriate shocks which impair patients' quality of life and may also be arrhythmogenic.

Evaluation and reduction of asymptomatic cerebral embolism in ablation of atrial fibrillation, but high prevalence of chronic silent infarction: results of the evaluation of reduction of asymptomatic cerebral embolism trial.

Background: This prospective, multicenter study sought to evaluate the incidence of asymptomatic cerebral emboli (ACE) during ablation of atrial fibrillation (AF) using a multielectrode radiofrequency (MER) system when specific procedural changes were applied.

Methods And Results: Sixty subjects (age 60±10 years; 87% paroxysmal; CHADS2 score, 0.6±0.

Ablation of paroxysmal and persistent atrial fibrillation with multielectrode phased radiofrequency duty-cycled catheters: long-term results from a large cohort of patients.

Background: Catheter ablation is a widely used approach to treat patients with drug refractory paroxysmal atrial fibrillation (PAF) and persistent atrial fibrillation (CAF). The aim of this analysis was to evaluate the long-term safety and efficacy of the multielectrode/phased radiofrequency (RF)/duty-cycled ablation catheters in the treatment of both PAF and CAF in a large cohort of patients.

Radiofrequency catheter ablation of atrial fibrillation in athletes referred for disabling symptoms preventing usual training schedule and sport competition.

Introduction: Atrial fibrillation (AF) may occasionally affect athletes by impairing their ability to compete, and leading to noneligibility at prequalification screening. The impact of catheter ablation (CA) in restoring full competitive activity of athletes affected by AF is not known. The aim of our study was to investigate the effectiveness of CA of idiopathic AF in athletes with palpitations impairing physical performance and compromising eligibility for competitive activities.

[Mitral regurgitation and left ventricular dysfunction: pathophysiology and surgical therapy].

Functional mitral regurgitation (FMR) is a distinctive valve disease in which the left ventricle is the "culprit" and the mitral valve is the "victim". It differentiates from organic regurgitation because the structure of the valve and subvalvar apparatus are not affected, hence abnormalities of the left ventricle are not the consequence but the cause of valve disease. It is at present well known that FMR conveys adverse prognosis in patients with left ventricular dysfunction, with a graded relationship between severity and reduced survival.

Importance of surgical timing on postoperative outcome in patients with native valve acute endocarditis.

Background: The present study was undertaken to establish whether surgical outcome could be influenced by surgical timing in patients affected by native valve endocarditis (NVE).
