OBJECTIVE The persistence of a left superior vena cava (LSVC) has been observed in 0.3% of the general population as established by autopsy. In the adult population, it is an important anatomic finding if a left superior approach to the heart is considered. The aim of the study was to evaluate the prevalence of a LSVC in patients undergoing pacemaker (PM)(More)
BACKGROUND AND PURPOSE Emery-Dreifuss muscular dystrophy (EDMD) is a rare inherited disorder associated with cardiac involvement. We investigated the spectrum and relevance of the cardiac manifestations of EDMD, focusing on bradyarrhythmias and tachyarrhythmias (including atrial fibrillation/flutter), embolic stroke, and heart failure. METHODS AND RESULTS(More)
BACKGROUND Heart failure(HF) and atrial fibrillation(AF) frequently coexist in the same patient and are associated with increased mortality and frequent hospitalizations. As the concomitance of AF and HF is often associated with a poor prognosis, the prompt treatment of AF in HF patients may significantly improve outcome. METHODS/DESIGN Recent implantable(More)
OBJECTIVE The aim of this study was to assess the association between maximum daily atrial fibrillation (AF) burden and risk of ischaemic stroke. BACKGROUND Cardiac implanted electronic devices (CIEDs) enhance detection of AF, providing a comprehensive measure of AF burden. DESIGN, SETTING, AND PATIENTS A pooled analysis of individual patient data from(More)
BACKGROUND The EURObservational Research Programme-Atrial Fibrillation General Registry Pilot Phase (EORP-AF Pilot) provides systematic collection of contemporary data regarding the management and treatment of 3119 subjects with AF from 9 member European Society of Cardiology (ESC) countries. In this analysis, we report the development of symptoms, use of(More)
BACKGROUND Phrenic stimulation (PS) may hinder left ventricular (LV) pacing. We prospectively observed its prevalence in consecutive patients with cardiac resynchronization therapy (CRT) devices. METHODS AND RESULTS In the years 2003 to 2006, 197 patients received a CRT device. PS and LV threshold measurements were carried out at implantation and at(More)
AIMS Cardiac resynchronization therapy (CRT) improves functional capacity and survival in heart failure. However, one-third of patients fail to respond to CRT. Resting left ventricular (LV) dyssynchrony assessed by echocardiography (ECHO) showed discordant results in identifying CRT responders. LV dyssynchrony can totally change during exercise. Aim of this(More)
Telecardiology may help confront the growing burden of monitoring the reliability of implantable defibrillators/pacemakers. Herein, we suggest that the evolving capabilities of implanted devices to monitor patients' status (heart rhythm, fluid overload, right ventricular pressure, oximetry, etc.) may imply a shift from strictly device-centered follow-up to(More)
