Different venous approaches for implantation of cardiac electronic devices. A network meta-analysis.

Objectives: Many of the complications arising from cardiac device implantation are associated to the venous access used for lead placement. Previous analyses reported that cephalic vein cutdown (CVC) is safer but less effective than subclavian vein puncture (SVP). However, comparisons between these techniques and axillary vein puncture (AVP) - guided either by ultrasound or fluoroscopy - are lacking.

The role of left atrial peak systolic strain in atrial fibrillation recurrence after catheter ablation. A systematic review and meta-analysis.

Background: This systematic review and meta-analysis was performed to assess the prognostic role of left atrial peak systolic longitudinal strain (LA-PLSsys) as a predictor of atrial fibrillation (AF) recurrence after catheter ablation.

Methods: We systematically searched major electronic databases and grey literature for studies assessing the role of pre-ablation LA-PLSsys, measured in at least two segments, in post-ablation AF recurrence, after a follow-up period of at least 6 months.

Results: Seventeen eligible studies were included, resulting in 1704 patients (68.

The prognostic role of late gadolinium enhancement on cardiac magnetic resonance in patients with nonischemic cardiomyopathy and reduced ejection fraction, implanted with cardioverter defibrillators for primary prevention. A systematic review and meta-analysis.

Background: Previous studies suggest that late gadolinium enhancement (LGE) on cardiac magnetic resonance (CMR) is associated with arrhythmic events in patients with nonischemic cardiomyopathy (NICM), while others have questioned the role of left ventricular ejection fraction (LVEF) as a sole predictor of future events.

Objectives: To evaluate the role of LGE on CMR in identifying patients with NICM and reduced LVEF for whom a benefit from defibrillator implantation for primary prevention is not anticipated, thus they are mainly exposed to potential risks.

Methods: Major electronic databases were searched for studies reporting the incidence of appropriate device therapy (ADT), sudden cardiac death (SCD), and cardiac death based on the presence of LGE on CMR, among patients with NICM and reduced LVEF, implanted with a cardioverter defibrillator for primary prevention.

A stand-alone structured educational programme after myocardial infarction: a randomised study.

Background: Acute myocardial infarction (MI) is a major clinical manifestation of coronary artery disease. Post-MI morbidity and mortality can be reduced by lifestyle changes and aggressive risk factor modification. These changes can be applied more effectively if the patient is actively involved in the process.
