Long-term follow-up after catheter ablation for atrioventricular nodal reentrant tachycardia: a comparison of cryothermal and radiofrequency energy in a large series of patients

Background Radiofrequency (RF) catheter ablation for atrioventricular nodal reentrant tachycardia (AVNRT) is highly successful but carries a risk for inadvertent atrioventricular block. Cryoablation (cryo) has the potential to assess the safety of a site before the energy is applied. Purpose The aim of this study was to evaluate the long-term efficacy and safety of cryothermal...

Radiofrequency ablation of coronary sinus-dependent atrial flutter guided by fractionated mid-diastolic coronary sinus potentials

BackgroundThe efficacy of radiofrequency (RF) ablation of an uncommon coronary sinus (CS)-dependent atrial flutter (AFL) was evaluated using conventional electrophysiological criteria in a highly selected subset of patients with typical and atypical AFL.MethodsFourteen patients with atrial flutter (11 males, mean age 69 ± 9 years) without previous right or left atrial RF ablation...

Knowledge, attitude, and behavior in patients with atrial fibrillation undergoing radiofrequency catheter ablation

Purpose Catheter ablation for atrial fibrillation (AF) has become a widely accepted procedure in most of the large cardiac centers throughout the world. However, little is known regarding the knowledge, attitude, and behavior (KAB) of AF patients undergoing radiofrequency catheter ablation (RFCA). Our purpose is to investigate the status and influencing factors of KAB in these...

Responsiveness of AF6, a new, short, validated, atrial fibrillation-specific questionnaire—symptomatic benefit of direct current cardioversion

Objectives To measure the effects on symptoms of electrical cardioversion (DC) in patients with atrial fibrillation (AF) by means of a new, short, validated, AF-specific questionnaire, the AF6. Methods One hundred eleven patients (67 ± 12 years, 89 men) were screened before and 12 ± 3 days after DC using AF6, covering ‘breathing difficulties at rest’, ‘breathing difficulties on...

Unexpected low prevalence of atrial fibrillation in cryptogenic ischemic stroke: a prospective study

Purpose Ischemic stroke is a frequent pathology with high rate of recurrence and significant morbidity and mortality. There are several causes of stroke, affecting prognosis, outcomes, and management, but in many cases, the etiology remains undetermined. We hypothesized that atrial fibrillation was involved in this pathology but underdiagnosed by standard methods. The aim of the...

Prospective multicenter randomized trial of fast ventricular tachycardia termination by prolonged versus conventional anti-tachyarrhythmia burst pacing in implantable cardioverter-defibrillator patients-Atp DeliVery for pAiNless ICD thErapy (ADVANCE-D) Trial results

Purpose The purpose of the trial was to quantify and compare the efficacy of two different sequences of burst anti-tachycardia pacing (ATP) strategies for the termination of fast ventricular tachycardia. Methods The trial was prospective, multicenter, parallel and randomized, enrolling patients with an indication for implantable cardioverter-defibrillator implantation. Results...

Successful catheter ablation of focal ventricular fibrillation originating from the right ventricle

Sudden cardiac death from ventricular fibrillation (VF) typically occurs in patients with structural heart disease, but in 5 to 10 percent VF is “idiopathic,” occurring in normal hearts. Recently, there has been the description and growing recognition of patients with VF that has a focal origin, the common sites being in the right ventricular outflow tract (RVOT) and sites in the...

Toward early diagnosis in arrhythmogenic right ventricular dysplasia/cardiomyopathy

Arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVD/C) is a myocardial disease which is histologically mainly localized in the right ventricle (RV) [1–3]. Histology shows fibrofatty replacement of the myocardium. At autopsy, diagnosis is usually straightforward. In the clinical setting, tissue is obtained by RV endomyocardial biopsies. For safety reasons, sampling is...

Electrical storm reversible by isoproterenol infusion in a striking case of early repolarization

A 40-year-old woman was referred to intensive care unit after recurrent ventricular fibrillation. She was free of cardiac medical history or medications. The resting ECG displayed an extended early repolarization in the inferior leads and all the precordial leads. Incessant ventricular fibrillations justified a treatment by intravenous amiodarone associated with general...

Typical atrial flutter can effectively be treated using single one-minute cryoapplications: Results from a repeat electrophysiological study

PurposeCatheter-based cryoablation (cryo) has proven to be as effective as radiofrequency energy (RF) ablation for the treatment of arrhythmias. Nevertheless, the duration of cryoapplications has been reported as being significantly longer than RF applications.MethodsThirty-seven consecutive patients (28 men; mean age 59 ± 14 years) with typical atrial flutter (AFL) underwent...

Electro-anatomical mapping of the left atrium before and after cryothermal balloon isolation of the pulmonary veins

IntroductionThe 28 mm cryoballoon catheter is a device used for pulmonary vein isolation (PVI). The aim of this study was to evaluate the extent of the ablation in the antral regions of the left atrium.Methods and ResultsEighteen patients with drug refractory, symptomatic, paroxysmal AF were enrolled. A 3D electroanatomic reconstruction of the left atrium was made before and...

Acute success and short-term follow-up of catheter ablation of isthmus-dependent atrial flutter; a comparison of 8 mm tip radiofrequency and cryothermy catheters

Objectives To compare the acute success and short-term follow-up of ablation of atrial flutter using 8 mm tip radiofrequency (RF) and cryocatheters. Methods Sixty-two patients with atrial flutter were randomized to RF or cryocatheter (cryo) ablation. Right atrial angiography was performed to assess the isthmus. End point was bidirectional isthmus block on multiple criteria. A...

Long term outcome of cavotricuspid isthmus cryoablation for the treatment of common atrial flutter in 180 patients: A single center experience

Objective Recent literature has shown that common type atrial flutter (AFL) can recur late after cavotricuspid isthmus (CTI) catheter ablation using radiofrequency energy (RF). We report the long term outcome of a large group of patients undergoing CTI ablation using cryothermy for AFL in a single center. Methods Patients with AFL referred for CTI ablation were recruited...

Transcatheter ablation of arrhythmias associated with congenital heart disease

The improvement of surgical techniques resulted in significant life prolongation of many young patients with congenital heart disease (CHD). However, as these patients reach adulthood, their risk for late complications associated with surgery is also increased. One of the most difficult challenges associated with CHD is the high incidence of cardiac arrhythmias that arise from...
