Untreated ventricular septal defect (VSD) is an important cause of congestive heart failure in early infancy. Growth is impaired in this population, and surgical closure is challenging because of congestion in the lungs, making infants prone to respiratory infection, and because of their poor nutritional status. The aim of this study is to share our experience with percutaneous VSD closure in patients under 1 year of age. Patients with hemodynamically significant left-to-right shunt, less than 1 year of age, and with VSD diameter ≤ 6 mm were retrospectively included in the study between December 2014 and January 2017...

OBJECTIVE: In patients indicated for cardiac resynchronisation therapy (CRT), the choice between a CRT-pacemaker (CRT-P) versus defibrillator (CRT-D) remains controversial and indications in this setting have not been well delineated. Apart from inappropriate therapies, which are inherent to the presence of a defibrillator, whether adding defibrillator to CRT in the primary prevention setting impacts risk of other acute and late device-related complications has not been well studied and may bear relevance for device selection...

INTRODUCTION: Intra-operative complications like mechanical damages to the leads, infections and hematomas during generator replacements of implantable pacemakers and defibrillators contribute to additional costs for hospitals. The aim of this study was to evaluate operation room use, costs and budget impact of generator replacements using either a traditional surgical intervention (TSI) with scissors, scalpel and electrocautery vs. a new radiofrequency energy based surgical system, called PEAK PlasmaBladeTM (PPB)...

BACKGROUND Cardiac device infection (CDI) is a serious complication of cardiovascular implantable electronic device (CIED) implantations. Many risk factors have been identified, but several are still uncertain. This study aimed to identify and evaluate the risk factors. Moreover, an infection control protocol (ICP) was carried out, and its efficacy in reducing CDIs was investigated. MATERIAL AND METHODS A total of 1259 patients who received permanent pacemaker (PPM) implantations were enrolled in this study in a 3-year period in a high-volume center and low-volume centers in the central area of Shaanxi Province, China...

Implants are commonly used as a replacement for damaged tissue. Many implants, such as pacemakers, chronic electrode implants, bone screws, and prosthetic joints, are made of or contain metal. Infections are one of the difficult to treat complications associated with metal implants due to the formation of biofilm, a thick aggregate of extracellular polymeric substances (EPS) produced by the bacteria. In this study, we treated a metal prosthesis infection model using a combination of ciprofloxacin-loaded temperature-sensitive liposomes (TSL) and alternating magnetic fields (AMF)...

The present study aimed to understand the biofilm formation mechanism of Propionibacterium acnes by analyzing the components and structure of the biofilms. P. acnes strains were isolated from the surface of explanted cardiac pacemaker devices that exhibited no clinical signs of infection. Culture tests using a simple stamp culture method (pressing pacemakers against the surface of agar plates) revealed frequent P. acnes colonization on the surface of cardiac pacemaker devices. P . acnes was isolated from 7/31 devices, and the isolates were categorized by multilocus sequence typing into five different sequence types (STs): ST4 (JK18...

Trypanosoma brucei ( T. b. ) gambiense is the parasite subspecies responsible for most reported cases of human African trypanosomiasis (HAT) or sleeping sickness. This severe infection leads to characteristic disruption of the sleep-wake cycle, recalling attention on the circadian timing system. Most animal models of the disease have been hitherto based on infection of laboratory rodents with the T. b. brucei subspecies, which is not infectious to humans. In these animal models, functional, rather than structural, alterations of the master circadian pacemaker, the hypothalamic suprachiasmatic nucleus (SCN), have been reported...

BACKGROUND Intracardiac abscesses are an unusual occurrence in developed countries. With the increase in use of implantable cardiac devices, the increase use of and advancements in antibiotics, and the longevity of patients with cardiac devices, one may expect an increase in such infections; however, case reports are rare. We are presenting a case in which hematogenous dissemination of methicillin-sensitive Staphylococcus aureus (MSSA) infection from a lower extremity diabetic ulcer propagated into an infected pacemaker lead and ultimately an intracardiac abscess of the right atrium...

The number of permanent pacemaker implantations has been increasing due to the aging of populations worldwide and the increase in the numbers of patients with heart diseases. Commercially available mechanical pacemakers are very useful but still have some problems including short battery life, a risk of infection, the absence of physiological autonomic responsiveness, metal allergy, and electronic interference. A biological pacemaker may resolve these problems and regenerate the cardiac pacemaker. Cell-based therapy and gene therapy have been addressed with the goal of solving the challenges of biological pacemaker...

This report presents and discusses, on behalf of the Belgian College of Cardiology, the evolution of the peer review process in arrhythmology, focussing on pacemaker implantation. Data from the last 22 years are compared. The national annual increase in implants is around 1%, clinical patient characteristics remained stable over the years while dual chamber pacing was proportionally increasing. Analyses of the normalised sick sinus and complete atrioventricular block ratios revealed a quite homogenous practice between centres and patient district with the only exception of the two more crowded districts...

We report an unusual case of an elderly man presenting with a fast-growing large malignant tumour involving the skin overlying his permanent pacemaker site. The fast-growing cutaneous squamous cell carcinoma appeared 2 years after pacemaker implantation. Joint specialist input was required to tackle this complex problem as a wide surgical excision would expose the pacemaker generator risking device infection particularly if the skin graft reconstruction failed. Having established that the patient had minimal pacing needs, it was determined through expedited multidisciplinary discussion that the best option was excision of the lesion with skin grafting of the defect by maxillofacial surgical team and pacemaker generator removal by a cardiologist in a joint surgical procedure...

BACKGROUND: Due to relatively newer technology, experience with retrieval of Micra transcatheter pacing system (TPS) is limited. Although, it is recommended to abandon the TPS at end of life, certain situations such as endovascular infections or device embolization warrant retrieval. OBJECTIVES: To report worldwide experience of successful retrieval for Micra TPS. METHODS: The list of all successful retrievals for the currently available leadless pacemakers (LPs) was obtained from the manufacturer of Micra TPS...

The 2017 Nobel Prize for Physiology or Medicine, awarded for the discoveries made in the past 15 years on the genetic and molecular mechanisms regulating many physiological functions, has renewed the attention to the importance of circadian rhythms. These originate from a central pacemaker in the suprachiasmatic nucleus in the brain, photoentrained via direct connection with melanopsin containing, intrinsically light-sensitive retinal ganglion cells, and it projects to periphery, thus creating an inner circadian rhythm...

With the increasing number of implanted pacemakers and implantable cardioverter defibrillators, removal is required more frequently. Presently described is the transvenous extraction of a 26-year-old Accufix atrial lead using a mechanical dilator sheath. A 50-year-old male patient was admitted to the clinic with a pacemaker pocket infection. The atrial lead was an Accufix Bipolar J-Atrial active fixation lead, a model that was recalled in 1994, after reports of 2 deaths and 2 nonfatal injuries related to protrusion of the J retention wire...

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...
