Efficacy and limitation of nonparoxysmal atrial fibrillation ablation in patients with heart failure with preserved ejection fraction

Journal of Cardiovascular Electrophysiology

Abstract Introduction Catheter ablation for atrial fibrillation (AF) reduces heart failure (HF) hospitalization in patients with HF with preserved ejection fraction (HFpEF). However, the long-term outcomes and subclinical HF after nonparoxysmal AF ablation in HFpEF patients have not been fully evaluated.

Catheter ablation of typical atrial flutter improves cardiac chamber size and function

Journal of Cardiovascular Electrophysiology

Abstract Introduction Cavo-tricuspid isthmus (CTI) dependent atrial flutter (AFL) is one of the most common atrial arrhythmias involving the right atrium (RA) for which radiofrequency catheter ablation has been widely used as a therapy of choice. Follow-up echocardiographic data was available for 55 patients. to 50.4 ± 14.9%, p  < .0001),

Case Report: Electroanatomic mapping as an early diagnostic tool in arrhythmogenic cardiomyopathy

Frontiers in Cardiovascular Medicine

Transthoracic echocardiogram revealed normal biventricular function and dimension. Twelve-lead ECG showed diffuse low-voltage QRS complexes. Holter monitor showed 28% burden of PVCs with various morphologies consistent with right ventricular (RV) inflow and outflow tract exits.
