Pulmonary Vein Stenosis After Atrial Fibrillation Ablation: Insights From the ADVICE Trial.

Background: Pulmonary vein (PV) stenosis is a complication of atrial fibrillation (AF) ablation. The incidence of PV stenosis after routine post-ablation imaging remains unclear and is limited to single-centre studies. Our objective was to determine the incidence and predictors of PV stenosis following circumferential radiofrequency ablation in the multicentre Adenosine Following Pulmonary Vein Isolation to Target Dormant Conduction Elimination (ADVICE) trial.

Hockey Games and the Incidence of ST-Elevation Myocardial Infarction.

Background: The association between diagnosed acute ST-elevation myocardial infarction (STEMI) and hockey games in the Canadian population is unknown.

Methods: We retrospectively analyzed the association between hockey games of the National Hockey League Montreal Canadiens and daily hospital admissions for acute STEMI at the Montreal Heart Institute, Canada.

Results: Between June 2010 and December 2014, a total of 2199 patients (25.
