BACKGROUND The incidence of atrial fibrillation (AF) after ablation of a cavotricuspid isthmus (CTI)-dependent atrial flutter (AFL) is high. OBJECTIVE The purpose of this study was to test the hypothesis that AFL and AF may be initiated by pulmonary vein triggers. This prospective randomized trial tested the efficacy of a standalone pulmonary vein(More)
AIMS The approach to infected cardiac devices has changed during recent decades. Optimal treatment is still a matter of debate, especially in pacemaker-dependent patients. Therefore, we investigated the management and outcome of patients with pacemaker infections in a single centre over four decades. METHODS AND RESULTS We conducted a retrospective(More)
BACKGROUND In patients with known atrial fibrillation (AF) different scores are utilized to estimate the risk of thromboembolic events and guide oral anticoagulation. Diagnosis of AF strongly depends on the duration of electrocardiogram monitoring. The aim of this study was to use established scores to predict the prevalence of AF. METHODS The CHADS2-(More)
Every tenth patient with a cardiac pacemaker or implantable cardioverter-defibrillator implanted is expected to have at least one lead problem in his lifetime. However, transvenous leads are often difficult to remove due to thrombotic obstruction or extensive neointimal fibrotic ingrowth. Despite its clinical significance, knowledge on lead-induced vascular(More)
The HATCH score [hypertension, age > 75 years, previous transient ischemic attack (TIA) or stroke (doubled), chronic obstructive pulmonary disease, heart failure (doubled)] has been established to identify patients who are at risk of developing persistent forms of AF. We investigated whether this score is associated with the prevalence of AF in order to(More)
Several tools have been invented for surgical atrial fibrillation (AF) ablation. In this study, we investigated the real world efficacy of intraoperative AF ablation (AFA) with radiofrequency-energy or cryo-ablation and performed an electro-anatomical remap in some patients with recurrences. Seventy-three consecutive patients (53 male, median age of 69 ± 7(More)
AIMS A significant proportion of patients presenting with paroxysmal supraventricular tachycardia (PSVT) has no electrocardiogram (ECG) documentation. In these patients an electrophysiological study (EPS) may be performed to facilitate the diagnosis. METHODS AND RESULTS In a prospective registry we compared the prevalence of inducible arrhythmias and the(More)
In addition to different types of single-tip ablation catheters for pulmonary vein (PV) reisolation, a newly developed circular mapping and ablation catheter (nMARQ®) has been available since 2013 and is currently used only in initial PV isolation procedures. In this prospective registry we present feasibility and efficacy data for PV reisolation procedures(More)
