The Utility of Coronary Revascularization to Reduce Ventricular Arrhythmias in Coronary Artery Disease Patients: A Systematic Review.

Ventricular arrhythmias (VA) are a major cause of morbidity and mortality in patients with coronary artery disease (CAD). Current guidelines recommend revascularization of significant CAD to improve survival in patients with ventricular fibrillation (VF), polymorphic ventricular tachycardia (VT), or those who are post-cardiac arrest. However, revascularization is not recommended for CAD patients with suspected scar-mediated monomorphic VT.

Catheter ablation alone versus catheter ablation with combined percutaneous left atrial appendage closure for atrial fibrillation: a systematic review and meta-analysis.

Background: Combined catheter ablation (CA) with percutaneous left atrial appendage closure (LAAC) may produce comprehensive treatment for atrial fibrillation (AF) whereby rhythm control is achieved and stroke risk is reduced without the need for chronic oral anticoagulation. However, the efficacy and safety of this strategy is still controversial.

Methods: This meta-analysis was reported according to the Preferred Reporting Items for Systematic Review and Meta-Analyses guidelines.
