Conclusion and Relevance Catheter ablation for AF in HFrEF is associated with improvement in patient-centered outcomes and surrogate outcomes when compared to st and ard medical therapy with or without device therapy
Background Atrial fibrillation ( AF ) among patients with heart failure with reduced ejection fraction ( HFrEF ) is associated with adverse clinical outcomes .
Our primary aim was to evaluate patient-centered outcomes and surrogate outcomes following catheter ablation ( CA ) of AF among patients with HFrEF compared to st and ard medical therapy with or without device therapy ( atrioventricular node ablation and cardiac resynchronization therapy ) .
Incidence and predictors of major complications from contemporary catheter ablation to treat cardiac arrhythmias.
BACKGROUND Up date d underst and ing of the risks of catheter ablation is important because techniques have evolved for procedures treating non-life-threatening as well as potentially lethal arrhythmias . OBJECTIVE This prospect i ve study sought to assess the incidence and predictors of major complications from contemporary catheter ablation procedures at a high-volume center . METHODS Over a 2-year period , 1,676 consecutive ablation procedures  were prospect ively evaluated for major complications throughout 30 days postprocedure . Predictors of major complications were determined in a multivariate analysis adjusted for demographics , clinical variables , ablation type , and procedural factors . RESULTS Rates of major complications differed between procedure types , ranging from 0.8 % for supraventricular tachycardia , 3.4 % for idiopathic ventricular tachycardia ( VT ) , 5.2 % for atrial fibrillation ( AF ) , and 6.0 % for VT associated with structural heart disease ( SHD ) .  Ablation type ( ablation for AF [ odds ratio ( OR ) 5.53 , 95 % confidence interval ( CI ) 1.81 to 16.83 ] , for VT with SHD [ OR 8.61 , 95 % CI 2.37 to 31.31 ] , or for idiopathic VT [ OR 5.93 , 95 % CI 1.40 to 25.05 ] all referenced to supraventricular tachycardia ablation ) , and serum creatinine level > 1.5 mg/dl ( OR 2.48 , 95 % CI 1.07 to 5.76 ) were associated with increased adjusted risk of major complications , whereas age , gender , body mass index , international normalized ratio level , hypertension , coronary artery disease , diabetes , and prior cerebrovascular accident were not associated with increased risk . CONCLUSION In a large cohort of contemporary catheter ablation  , major complication rates ranged between 0.8 % and 6.0 % depending on the ablation procedure performed . Aside from ablation type , renal insufficiency was the only independent predictor of a major complication
