Background The relationship between health care utilization and outcomes in patients with atrial fibrillation is unknown. The objective of this study was to investigate whether cardiologists' billing amounts in a fee-for-service environment are associated with better patient-level clinical outcomes. Methods and Results A retrospective cohort study was conducted using administrative claims data of cardiologists in Ontario, Canada between April 1, 2011 and March 31, 2016.
View Article and Find Full Text PDFBackground/purpose: Interventional cardiac electrophysiology (EP) is a rapidly evolving field in Canada; a nationwide registry was established in 2011 to conduct a periodic review of resource allocation.
Methods: The registry collects annual data on EP lab infrastructure, imaging, tools, human resources, procedural volumes, success rates, and wait times. Leading physicians from each EP lab were contacted electronically; participation was voluntary.
Background: The choice of antithrombotic therapy for atrial fibrillation (AF) patients who have an acute coronary syndrome (ACS) or have undergone percutaneous coronary intervention (PCI) is challenging. We aimed to assess outcomes between dual-antithrombotic therapy with the use of direct-acting oral anticoagulants (DOACs) plus an antiplatelet agent (dual therapy) compared with warfarin plus 2 antiplatelet agents (triple therapy) for AF patients after PCI or with ACS.
Methods: Systematic searches of multiple major databases were performed from their inception through September 2019.
Outcomes of ICDs and CRTs in patients with chronic kidney disease: a meta-analysis of 21,000 patients.

Purpose: The efficacy of implantable cardioverter defibrillator (ICD) and cardiac resynchronization therapy (CRT) in patients with chronic kidney disease (CKD) remains unclear. The aim of this meta-analysis is to explore the association between ICD/CRT and mortality in CKD patients.
Methods: An electronic search was conducted using MEDLINE.
Aims: Several pacing modalities across multiple manufacturers have been introduced to minimize unnecessary right ventricular pacing. We conducted a meta-analysis to assess whether ventricular pacing reduction modalities (VPRM) influence hard clinical outcomes in comparison to standard dual-chamber pacing (DDD).
Methods And Results: An electronic search was performed using Cochrane Central Register, PubMed, Embase, and Scopus.
Background: Catheter-tissue contact is essential for effective lesion formation, thus there is growing usage of contact force (CF) technology in atrial fibrillation ablation. We conducted a meta-analysis to assess the impact of CF on clinical outcomes and procedural parameters in comparison to conventional catheter for atrial fibrillation ablation.
Methods And Results: An electronic search was performed using major databases.
Background: Dual-chamber (DDD) and VDD pacing are recognized alternatives for patients with advanced atrioventricular (AV) conduction abnormalities and spared sinus node function. The comparative data between these 2 modes are limited.
Methods: A literature search was performed using multiple major databases.
Purpose: Interventional cardiac electrophysiology (EP) has experienced a significant growth in Canada. Our aim is to establish a periodic registry as a nationwide initiative.
Methods: The registry is designed to collect information regarding EP laboratory infrastructure, human resources, and the spectrum and volumes of EP procedures.
