We sought to investigate the clinical, electrocardiographic, and electrophysiological characteristics of left upper septal fascicular ventricular tachycardia (LUS-VT).Eleven consecutive patients with LUS-VT were identified among 196 (VT). Clinical VTs presented as paroxysmal in 8 incessant 3 patients. Six had previous posterior VT ablation history. All narrow QRS complexes duration 101.1 ± 9.2 ms. The frontal axis was normal or right deviation. Precordial morphology either bundle branch...
The accessory pathway (AP) connecting the right atrial appendage (RAA) and ventricle (RV) is rare.We sought to investigate feature of AP RAA RV efficacy radiofrequency catheter ablation via endocardial access.We retrospectively analyzed 14 consecutive patients with APs managed by 15 procedures between January 2003 December 2014.Ten presented as preexcitation during sinus rhythm. All had retrograde conduction. None either antegrade or decremental conduction property. Ablation targeting sites...
Abstract Introduction The procedural findings and clinical outcome of second‐generation cryoballoon (CB2) ablation in patients with variant pulmonary vein (PV) anatomy have not been fully investigated. Methods A total 424 consecutive who underwent PV isolation CB2 were included. Computed tomographic (CT) scan was performed all before the procedure. study population divided into common PV, accessory nonvariant groups according to CT scan. Procedural between three compared. Results Variant...
Background: Common ostium of inferior pulmonary veins (COIPV) is a kind vein variation. The safety and efficacy COIPV isolation using the second-generation cryoballoon (CB) ablation remain unknown. Methods: A total 10 patients with from consecutive series 1,751 atrial fibrillation (AF) were included. Pulmonary (PVI) was performed CB. Results: prevalence 0.57% in this study. PVI achieved all (PVs) without need for touch-up. segmental freeze strategy applied each PV, respectively. mean number...
Abstract Background Ablation within the pulmonary sinus of Valsalva (PSV) becomes increasingly common in certain ventricular outflow arrhythmia. Understanding regional anatomy is intensively concerned to avoid procedure complications. Purpose To describe anatomic relationships PSV its adjacent structures using computed tomographic coronary angiograms (CTCA). Methods We studied 145 patients (77 males, age 47 ± 18 years) investigated for chest pain with CTCA. The between and were described by...
Abstract Background Radiofrequency (RF) catheter ablation of para‐Hisian accessory pathways (APs) can be challenging due to proximity the conduction system. Methods A total 30 consecutive patients with AP were enrolled for in three centers, 12 (40%) whom had previously failed attempted from inferior vena cava (IVC) approach. Ablation was preferentially performed using a superior approach (SVC) all patients. Results The eliminated SVC 28 (93.3%) In remaining two patients, additional IVC...
This study describes the electrophysiologic characteristics of para-hisian accessory pathway (AP), outcome different ablation approaches, and safety at sites.A total 120 patients diagnosed as AP were included in this study. The outcomes sites analyzed.In total, 107 APs 13 right anteroseptal (RAS) midseptal (RMS), respectively. significant ECG difference between RAS RMS was lead III, which mainly manifested positive negative delta waves, Catheter trauma to recorded 21 (17.5%) patients....
We aimed to examine the electrocardiographic and electrophysiologic characteristics of anterograde-conducting decremental accessory pathways (DAP) identify surrogate criteria distinguish short atrioventricular (SAV) DAP from atriofascicular (AF) AP long (LAV) DAP.We identified all patients with DAPs analysed characteristics. Distal insertion sites were examined using existing criteria, including V-H interval, ventricular activation at right apex, around tricuspid annulus during antidromic...
Abstract Aims Traditional ablation strategies including targeting the earliest Purkinje potential (PP) during left posterior fascicular (LPF) ventricular tachycardia (VT) or linear at middle segment of LPF sinus rhythm are commonly used for treatment LPF-VT. Catheter LPF-VT fragmented antegrade (FAP) is a novel approach. We aimed to compare safety and efficacy different (FAP vs. traditional ablation) Methods results Consecutive patients with electrocardiographically documented referred...
Objective To observe the clinical characters and electrophysiological features in patients with typical atrial flutter (AFL) combined focal tachycardia (FAT). Methods From March 2009 to September 2014, AFL undergoing studies center of arrhythmia, Fuwai Cardiovascular Hospital were enrolled study, characteristics collected. Result Two hundred sixty three enrolled.Among them, 6 different FAT recorded 5 (1.9%) including originated from upper Crista two cases; right pulmonary vein...
