Treatment with antiarrhythmic drugs and anticoagulation is considered first-line therapy in patients symptomatic atrial fibrillation (AF). Pulmonary vein isolation (PVI) radiofrequency ablation may cure AF, obviating the need for anticoagulation.To determine whether PVI feasible as treating AF.A multicenter prospective randomized study conducted from December 31, 2001, to July 1, 2002, of 70 aged 18 75 years who experienced monthly AF episodes at least 3 months had not been treated...
Pulmonary-vein isolation is increasingly being used to treat atrial fibrillation in patients with heart failure.In this prospective, multicenter clinical trial, we randomly assigned symptomatic, drug-resistant fibrillation, an ejection fraction of 40% or less, and New York Heart Association class II III failure undergo either pulmonary-vein atrioventricular-node ablation biventricular pacing. All completed the Minnesota Living Failure questionnaire (scores range from 0 105, a higher score...
The objective of this study was to assess the impact intracardiac echocardiography (ICE) on long-term success and complications in patients undergoing pulmonary vein isolation (PVI) for treatment atrial fibrillation (AF).Three hundred fifteen underwent PVI AF. Each patient ostial all PVs using a cooled-tip ablation catheter. performed circular mapping (CM) alone (group 1, 56 patients), CM ICE 2, 107 with titration radiofrequency energy based visualization microbubbles by 3, 152 patients)....
Background— The role of pulmonary vein (PV) isolation in ablative treatment atrial fibrillation (AF) has been debated conflicting reports. We sought to compare PV conduction patients who had no AF recurrence (group I), could maintain sinus rhythm on antiarrhythmic medication II), and recurrent despite III) after antrum (PVAI). Methods Results— was examined consecutive undergoing second PVAI for recurrence. also recruited some cured undergo a repeat, limited electrophysiological study at...
Effects of contact force (CF) on lesion formation during pulsed field ablation (PFA) have not been well validated. The purpose this study was to determine the relationship between average CF and size PFA using a swine-beating heart model.
Oral anticoagulation is recommended after ablation for atrial fibrillation among patients at high risk stroke. Left appendage closure a mechanical alternative to anticoagulation, but data regarding its use are lacking.
Pulmonary vein (PV) stenosis is a complication of ablation for atrial fibrillation. The impact different strategies on the incidence PV and its functional characterization has not been described.PV isolation was performed in 608 patients. An electroanatomic approach used 71 circular mapping 537 (distal isolation, 25; ostial based angiography, 102; guided by intracardiac echocardiography, 140; with energy delivery visualization microbubbles, 270). Severe (> or =70%) narrowing detected 21...
Background —Standard mapping and ablation of focal sources atrial fibrillation are associated with very long procedure times low efficacy. An anatomic approach to complete pulmonary vein isolation could overcome these limitations. Methods Results —Fifteen patients refractory medication underwent circumferential the veins by using a novel catheter, an ultrasound transducer (8-MHz) mounted near tip, in saline-filled balloon. Twelve foci and/or triggers were identified 9 (pulmonary locations:...
Pulmonary vein isolation is a new, effective curative procedure for selected patients with atrial fibrillation. stenosis potential complication and may lead to symptoms that are often underrecognized.To describe the clinical course associated pulmonary developing after ablation in veins.Retrospective study.Tertiary care referral center.335 referred catheter of drug-refractory fibrillation.Pulmonary electrical using radiofrequency ablation.Three months ablation, underwent routine screening...
Background— The best approach to management of anticoagulation before and after atrial fibrillation ablation is not known. Methods Results— We compared outcomes in consecutive patients undergoing pulmonary vein antrum isolation for persistent fibrillation. Early our practice, warfarin was stopped 3 days ablation, a transesophageal echocardiogram performed rule out clot. Enoxaparin, initially 1 mg/kg twice daily (group 1) then 0.5 2), used “bridge” ablation. Subsequently, continued maintain...
Background— Left atrioesophageal fistula is a rare but devastating complication that may occur after catheter ablation of atrial fibrillation. We used capsule endoscopy to assess esophageal injury for fibrillation in population randomized undergo general anesthesia or conscious sedation. Methods and Results— Fifty patients undergoing paroxysmal symptomatic refractory antiarrhythmic drugs were enrolled randomized, including those the procedure under (25 patients, group 1) receiving sedation...
The epicardial location of an arrhythmia could be responsible for unsuccessful endocardial catheter ablation.In 48 patients referred after prior ablation, we considered percutaneous, subxiphoid instrumentation the pericardial space mapping and ablation. Thirty had ventricular tachycardia (VT), 6 a right- 4 left-sided accessory pathway (AP), inappropriate sinus tachycardia, atrial arrhythmias. Of 30 VTs, 24 (6 with ischemic cardiomyopathy, 3 idiopathic 15 normal hearts) appeared to originate...
Ablation of atrial fibrillation is generally considered safe and effective. However, atrial-esophageal fistulas have recently been reported as a rare but fatal complication.To describe 9 patients with after ablation for fibrillation.Retrospective case series.Institutions where cardiologists performed procedures.9 ablation.Demographic characteristics, mortality, presenting signs symptoms, days to presentation.Patients presented mean 12.3 (range, 10 16 days) their procedures. Nonspecific...
Left atrioesophageal fistula is a devastating complication of atrial fibrillation ablation. There no standard approach for avoiding this complication, which caused by thermal injury during The objectives study were to evaluate the course esophagus and temperature within pulmonary vein antrum isolation (PVAI) correlate these data with tissue damage.Eight-one patients presenting PVAI underwent evaluation that included probe placement. Esophagus was obtained computed tomography, 3D imaging...
