PURPOSE: Recent studies suggest that atrial fibrillation (AF) is associated with increased cardiovascular risk and mortality including sudden cardiac death (SCD). According to the Cardiovascular Heath Study cohort, the incident rate of SCD was higher in the AF population (2.9 per 1000 per year) compared with non-AF controls (1.3 per 1000 per year). In this study, we performed a systematic review and meta-analysis to explore the association between AF and SCD. METHODS: We comprehensively searched the databases of MEDLINE and EMBASE from inception to January 2017...

The demand for tricuspid valve (TV) surgery has increased continuously these last years. Recent registry data have confirmed that TV repair or replacement carry an increased risk of conduction disorders requiring permanent pacemaker implantation, specifically for patients having multivalve surgery. The implantation of an endocardial right ventricular lead in those patients may impair TV function, and some other approaches may be discussed to avoid traversing the valve. This contemporary review describes the different options currently available for patients requiring pacemaker or defibrillation leads implantation after TV surgery...

With the alarming rise in the deaths due to cardiovascular diseases (CVD), present medical research scenario places notable importance on techniques and methods to detect CVDs. As adduced by world health organization, technological proceeds in the field of cardiac function assessment have become the nucleus and heart of all leading research studies in CVDs in which electrocardiogram (ECG) analysis is the most functional and convenient tool used to test the range of heart-related irregularities. Most of the approaches present in the literature of ECG signal analysis consider noise removal, rhythm-based analysis, and heartbeat detection to improve the performance of a cardiac pacemaker...

BACKGROUND: A proportion of patients who undergo an initial lead extraction procedure will require a second, repeat extraction. Data regarding this clinical entity are scarce and neither the predisposing risk factors for, nor outcomes from these procedures have been described previously. We sought to determine the incidence, risk factors and outcomes of repeat lead extraction. METHODS: A database of extraction procedures from 2001-2015 was analyzed. Repeat extraction procedures were identified and the indication for extraction was dichotomized into infection and lead related problems...

This report describes the occurrence of desynchronization in a patient with a cardiac resynchronization device programmed with an active pacemaker-mediated tachycardia algorithm based on AV delay modification. Desynchronization was precipitated by sinus tachycardia and the abrupt return of the prevailing AV delay that followed the periodic prolongation of the AV delay mandated by activity of the algorithm. Prevention of desynchronization in this setting requires programming a right ventricular upper rate interval longer than the sum of the programmed ventriculoatrial interval and the AV delay...

Cardiac management devices have become an integral part of our armament for treatment of heart diseases. However, complications may arise mandating extraction of either the device or the lead. The non-interventional lead extraction has become a topic of avid debate as simple traction is associated with low success rates while laser-assisted extraction carries a high economic cost. Herein we present a case of 22-year-old pacemaker leads extracted with a novel "trouser-like technique" that could present an attractive alternative for leads implanted in a time lapse of more than 10 years when laser sheaths are not accessible...

BACKGROUND: Although next-generation cardiac prostheses have shown favorable results in transcatheter aortic valve implantation (TAVI), these have mostly been documented in intermediate-risk patients. Whether this could be translated to high-risk patients is not known. Hence, the safety and clinical performance of the new, repositionable CoreValve Evolut R-System (ERS) was evaluated by comparison with a non-repositionable CoreValve-System (CVS), in 96 high-risk/inoperable (HRI) patients...

The purpose of this patient survey was to analyse the knowledge, experiences, and attitudes regarding cardiac implantable electronic devices (CIED) in patients with pacemakers, implantable cardioverter-defibrillators (ICDs), or cardiac resynchronization devices. Of the 1644 patients with CIEDs from seven European countries, 88% were over 50 years of age. Most patients (90%) knew what device they were implanted with and felt sufficiently informed about the indications for therapy. As many as 42% of patients needed additional information on the battery replacement and limitations in physical activity...

BACKGROUND: Patients who have pacemakers or defibrillators are often denied the opportunity to undergo magnetic resonance imaging (MRI) because of safety concerns, unless the devices meet certain criteria specified by the Food and Drug Administration (termed "MRI-conditional" devices). METHODS: We performed a prospective, nonrandomized study to assess the safety of MRI at a magnetic field strength of 1.5 Tesla in 1509 patients who had a pacemaker (58%) or an implantable cardioverter-defibrillator (42%) that was not considered to be MRI-conditional (termed a "legacy" device)...
