Background— During the past years, many innovations have been introduced to facilitate catheter ablation of post–myocardial infarction ventricular tachycardia. However, predictors outcome after were not thoroughly studied. Methods and Results— From 2009 2013, consecutive patients referred for tachycardia included. The end point procedure was complete elimination local abnormal activities (LAVA) (VT) noninducibility. with primary VT recurrence assessed. A total 125 included (age: 64±11 years;...
Background: Biatrial tachycardia (BiAT) is a rare form of atrial macroreentrant tachycardia, in which both atria critical part the circuit. We aimed to identify characteristics and precise circuits single-loop BiATs. Methods Results: identified 8 patients (median age, 59.5 years old) with 9 BiATs cohort 336 consecutive from 2 institutions who had undergone AT catheter ablation using an automatic ultrahigh-resolution mapping system. Seven history persistent AF ablation, including septal or...
Background— The correlates of left ventricular (LV) substrate in arrhythmogenic right (RV) cardiomyopathy are largely unknown. Methods and Results— Thirty-two patients with RV (47±14 years; 6 women) were included. LV dysplasia defined from multidetector computed tomography cardiac magnetic resonance imaging. Arrhythmias characterized as right-sided or left-sided on 12-lead ECG recordings at baseline during isoproterenol testing. In 14 patients, the imaging was compared voltage mapping local...
Abstract Introduction Pulmonary vein (PV) reconnection is frequent in patients showing atrial fibrillation (AF) recurrence after PV isolation (PVI). Its detection with cardiac magnetic resonance (CMR) may help predict outcome and guide redo procedures. We assessed the relationship between scar on CMR catheter ablation for paroxysmal AF. Methods Results Fifty‐one AF underwent before PVI using either a conventional single‐electrode (N = 28) or circular multielectrode 23). At 3 months, second...
Abstract Introduction It is largely believed that atrial tachycardias (ATs) encountered during ablation of persistent fibrillation (PsAF) are a byproduct ablative lesions. We aimed to explore the alternative hypothesis they may be priori drivers AF remaining masked until other sources reduced or eliminated. Methods and results Radiofrequency fibrillatory mapped by electrocardiographic imaging (ECGI; ECVUE™, Cardioinsight Technologies, Cleveland, OH, USA) terminated PsAF in 198 (73%) out 270...
Ablative pulmonary vein isolation (PVI) decreases (PV) and left atrial (LA) dimensions in fibrillation (AF) patients. These changes are attributed to reverse structural remodeling following sinus rhythm restoration but evidence is lacking. We hypothesized that the downsizing directly caused by ablative energy subsequent scar formation.
Aim: We sought to analyze electrophysiological effects of amiodarone in patients with persistent atrial fibrillation (AF). Methods: included 156 consecutive AF duration less than 12 months who underwent a first procedure ablation. The consisted driver ablation based on non contact mapping (ECVUE, CardioInsight Technologies Inc, Cleveland, OH). Clinical and findings were compared between 82 74 without amiodarone. Results: Patients had more frequently history structural heart disease (SHD)...
Introduction: Anatomical macroreentrant atrial tachycardias (MATs) are conventionally reported to depend on cavotricuspid isthmus (CTI), mitral (MI), and left roof, often occurred after catheter ablation (CA) of fibrillation. However, the precise assessment these conventional anatomical MATs in patients with prior ablations has not been fully reported. Currently, Rhythmia mapping system a high-density basket become available. The purpose this study was elucidate characteristics guided by...
We are reporting a case of young Nepalese man, who was not known to have any past medical history, and presented with palpitations. An electrocardiogram showed negative P-waves atrial rhythm in II, III, arteriovenous fistula, V3-V6 variable block at 90-130 bpm. No positive "normal" were demonstrated tracing. He found congenital absence the right superior vena cava (RSVC) along persistent left (PLSVC) condition also called isolated PLSVC (IPLSC). underwent treadmill stress test for further...
