Key Points

To review major clinical trials and technical innovations in invasive electrophysiology and device therapy published in 2014 with potential impact on clinical guidelines.
Synthesized findings from randomized trials, registries, and consensus documents covering arrhythmia mechanisms, stroke prevention, and electrophysiological interventions.
Evaluated clinical data across endurance-exercise cohorts, catheter ablation strategies, novel oral anticoagulants, and subcutaneous or leadless devices.
High endurance exercise in 52,755 cross-country skiers was linked to increased risks of atrial fibrillation (HR 1.29) and bradyarrhythmias (HR 2.10) among frequent and top finishers.
Short-term amiodarone after ablation in the AMIO-CAT trial (n=212) significantly reduced 3-month arrhythmia hospitalizations (RR 0.43; 95% CI 0.23–0.77; P=0.006) and cardioversions (RR 0.36; 95% CI 0.20–0.62; P=0.0004), despite no difference in 6-month recurrence.
Real-world data from 1,300 ablation patients across 72 European centers showed antiarrhythmic drug-free success in 40.7% at one year, while emerging leadless pacemakers and subcutaneous defibrillators demonstrated promising initial clinical efficacy.

Review

Implication

This 2014 year-in-review highlights critical advancements in arrhythmia management, particularly in AF ablation techniques and the practical application of non-vitamin K antagonist oral anticoagulants.
