Catheter ablation of atrial fibrillation in heart failure with reduced ejection fraction.

abstract：:Enduring isolation of the pulmonary veins (PV) is becoming increasingly common in patients undergoing repeat catheter ablation for atrial fibrillation. We describe our approach to ablation strategy in a patient with enduring isolation of PV and briefly discuss the role of non-PV triggers. ...
