BACKGROUND Early recurrence of atrial fibrillation (ERAF) after catheter ablation is common and has been thoroughly studied. However, very late recurrence of atrial fibrillation (VLRAF) is rarely researched, and its characteristics have not been determined. HYPOTHESIS The aim of this study was to investigate the clinical characteristics of VLRAF after(More)
OBJECTIVE Previous studies have shown that angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin II receptor blockers (ARBs) could reverse structural and electrical atria remodelling and decrease atrial fibrillation (AF) onset or recurrence. The aim of this retrospective study was to investigate whether ACEIs/ARBs had beneficial effects on(More)
BACKGROUND Catheter ablation can restore sinus rhythm in selected patients with atrial fibrillation (AF), but its preventive function for thromboembolic events (TE) is still underdetermined. METHODS We retrospectively studied 520 consecutive patients with AF who were referred for circumferential pulmonary vein ablation. The incidence of late TE was(More)
INSTRUCTION Preablation transesophageal echocardiography (TEE) is dispensable for the patients with planned catheter ablation for atrial fibrillation (AF) and having received at least a 3-week oral anticoagulation therapy according to the recommendations of the Venice Consensus. But the role of prior TEE and the effect of preablation short-term oral(More)
INTRODUCTION The reliability of delayed cure of early recurrence of atrial fibrillation (ERAF) is still undetermined. Furthermore, the predictors of recurrence after delayed cure of ERAF are less investigated in depth. AIMS OF THE STUDY The purpose of this study was to investigate the long-term efficacy of delayed cure of ERAF after catheter ablation of(More)
Atrial fibrillation (AF) and congestive heart failure (CHF) often coexist (AF-CHF), and each adversely affects the other with respect to management and prognosis. Therapy with antiarrhythmic drugs to maintain sinus rhythm was disappointing. Ablation is more successful than antiarrhythmic drug therapy for the prevention of AF with few complications, although(More)
Straight back syndrome (SBS) is a thoracic deformity with absence of upper thoracic spine kyphosis and heart compression. The anatomic abnormity of SBS may raise the difficulty of introcardial operation and increase the complicated risk of intervention performance. Here we report a case of SBS with complicated transseptal puncture during intervention(More)
Complex fragment atrial electrograms (CFAEs) are fractionated or discrete atrial wave fronts that frequently mapped in chronic atrial fibrillation (CAF). The CFAEs areas represent slow conduction and/or functional blocks that play substrate role in AF. Compared with the limited efficacy of pulmonary veins (PVs) oriented ablation strategy for CAF, few(More)
