BACKGROUND Single procedure success rates of pulmonary vein isolation (PVI) in patients with paroxysmal atrial fibrillation (PAF) are still unsatisfactory. In patients with persistent atrial fibrillation (AF), ablation of complex fractionated atrial electrograms (CFAEs) after PVI results in improved outcomes. OBJECTIVE We aimed to investigate if(More)
Atrial arrhythmias lower the biventricular pacing percentage in cardiac resynchronization therapy (CRT) treated patients (pts) and have a high prevalence in this population. External electrical cardioversion (ECV) is commonly performed to restore sinus rhythm. There is a paucity of data on the safety and efficacy of ECV in pts with CRT devices. Forty-three(More)
Catheter ablation of atrial fibrillation has evolved as a widely accepted therapy approach and is now also incorporated in the current guidelines.A major limitation consists of the limited three-dimensional visualization of the complex three-dimensional structures in the left atrium since most procedures have routinely been performed using fluoroscopy(More)
AIMS Propofol sedation has been shown to be safe for atrial fibrillation ablation and internal cardioverter-defibrillator implantation but its use for catheter ablation (CA) of ventricular tachycardia (VT) has yet to be evaluated. Here, we tested the hypothesis that VT ablation can be performed using propofol sedation administered by trained nurses under a(More)
A relevant number of patients presenting for electrical cardioversion carry a pacemaker (PM) or ICD. Case reports suggest a potential hazard of external cardioversion/defibrillation. The incidence of shock related device complications is unknown. No guidelines or recommendations by international medical societies for a cardioversion protocol of(More)
INTRODUCTION Catheter ablation of atrial fibrillation (AF) is an established rhythm control strategy; however, the impact of co-existing LV systolic dysfunction (LVSD) on ablation success is less well understood. This systematic review compiles the outcomes of catheter ablation of atrial fibrillation in patients with LVSD. METHODS An electronic database(More)
BACKGROUND External biphasic electrical cardioversion (CV) is a standard treatment option for patients suffering from acute symptoms of atrial fibrillation (AF). Nevertheless, CV is not always successful, and thus strategies to increase the success rate are desirable. OBJECTIVE The purpose of this study was to evaluate the effect of intravenously(More)
Vorhofflimmern (VHF) betrifft annährend 35 Mio. Menschen weltweit und ist mit schwerwiegenden Folgeschäden assoziiert. Neben den bekannten und gleichermaßen limitierten medikamentösen Behandlungsoptionen hat sich die Katheterablation als sichere und effektive interventionelle Therapieoption insbesondere bei paroxysmalem VHF etabliert. Die Pulmonalvenen (PV)(More)
BACKGROUND In the meantime, catheter ablation is widely used for the treatment of persistent atrial fibrillation (AF). There is a paucity of data about long-term outcomes. This study evaluates (1) 5-year single and multiple procedure success and (2) prognostic factors for arrhythmia recurrences after catheter ablation of persistent AF using the stepwise(More)
BACKGROUND Catheter ablation (CA) of ventricular tachycardia (VT) is an important treatment option in patients with structural heart disease (SHD) and implantable cardioverter defibrillator (ICD). A subset of patients requires epicardial CA for VT. OBJECTIVE The purpose of the study was to assess the significance of epicardial CA in these patients after a(More)
