Physiological mechano-acoustic signals, often with frequencies and intensities that are beyond those associated with the audible range, provide information of great clinical utility. Stethoscopes and digital accelerometers in conventional packages can capture some relevant data, but neither is suitable for use in a continuous, wearable mode, and both have shortcomings associated with mechanical transduction of signals through the skin. We report a soft, conformal class of device configured specifically for mechano-acoustic recording from the skin, capable of being used on nearly any part of the body, in forms that maximize detectable signals and allow for multimodal operation, such as electrophysiological recording...

BACKGROUND: Cardiovascular implantable electronic device (CIED) infections are associated with morbidity and mortality. Peri-operative systemic intravenous antibiotic prophylaxis reduces the rate of CIED infections. AIGISRx, a polymer envelope implanted with the CIED, releases minocycline and rifampin, and has been introduced to reduce infections. METHODS: Retrospective review of 184 patients who underwent CIED implantation was conducted. Ninety-two patients were implanted with an AIGISRx envelope (AIGISRx group) and 92 patients were not implanted with an AIGISRx envelope (control group)...

Importance: Subclinical atrial fibrillation (AF) is associated with an increased risk for stroke. Observations: Subclinical AF is asymptomatic, short in duration, and usually detected with long-term, continuous monitoring. Most prior studies have explored its consequences using cardiovascular implantable electronic devices (CIEDs). Although current prevalence estimates are derived from study populations with prior CIEDs, 3 trials will assess the time to a first AF diagnosis among patients receiving a CIED for purposes of AF detection...

Outcome of patients with coronary artery disease has been significantly improved by percutaneous coronary interventions with stent implantation. However, despite progress made on devices and antithrombotic treatments, stent thrombosis remains an important issue because of serious adverse consequences. Several mechanisms are assumed to favor stent thrombosis as platelet aggregation, fibrin formation, defective healing and local inflammation. The objective of this study was to evaluate in vitro the thrombogenicity, proinflammatory properties and healing capacities of cobalt-chromium (CoCr), an alloy commonly used for cardiovascular implants...

The number of patients with heart failure implantable cardiac electronic devices (CIEDs) is growing. Hospitalization rate in this group is very high and generates enormous costs. To avoid the need for hospital treatment, optimized monitoring and follow-up is crucial. Remote monitoring (RM) has been widely put into practice in the management of CIEDs but it may be difficult due to the presence of differences in systems provided by device manufacturers and loss of gathered data in case of device reimplantation...

INTRODUCTION: Percutaneous aortic valve replacement (transcatheter aortic valve implantation (TAVI)) notably increases the likelihood of the appearance of a complete left bundle branch block (LBBB) by direct lesion of the LBB of His. This block can lead to high-grade atrioventricular conduction disturbances responsible for a poorer prognosis. The management of this complication remains controversial. METHOD AND ANALYSIS: The screening of LBBB after TAVI persisting for more than 24 hours will be conducted by surface ECG...

Nanostructured biomaterials have been investigated for achieving desirable tissue-material interactions in medical implants. Ultrananocrystalline diamond (UNCD) and nanocrystalline diamond (NCD) coatings are the two most studied classes of synthetic diamond coatings; these materials are grown using chemical vapor deposition and are classified based on their nanostructure, grain size, and sp(3) content. UNCD and NCD are mechanically robust, chemically inert, biocompatible, and wear resistant, making them ideal implant coatings...

Cardiovascular implantable electronic device (CIED) infection and prosthetic valve endocarditis (PVE) remain a diagnostic challenge. Cardiac imaging plays an important role in the diagnosis and management of patients with CIED infection or PVE. Over the past few years, cardiac radionuclide imaging has gained a key role in the diagnosis of these patients, and in assessing the need for surgery, mainly in the most difficult cases. Both (18)F-fluorodeoxyglucose positron emission tomography/computed tomography ((18)F-FDG PET/CT) and radiolabelled white blood cell single-photon emission computed tomography/computed tomography (WBC SPECT/CT) have been studied in these situations...

Cardiovascular implantable electronic devices (CIEDs) have become a critical component in management of patients with cardiac rhythm disturbances, heart failure, and prevention of sudden cardiac death. However, infection remains a major complication of CIED implantation and is associated with significant morbidity and mortality for device recipients. Early-onset CIED infections frequently originate from the generator pocket, secondary to device or pocket contamination at the time of implantation, and may progress to involve device leads or cardiac valves...

Complete hardware removal is recommended in the case of patients with cardiovascular implantable electronic device (CIED) infections. However, the complete extraction of chronically implanted leads is not always achieved. The outcomes and optimal management of CIED infections with retained material after lead extractions have not been elucidated. In this case report, we present five patients with CIED infections with remnant lead tips even after lead extractions. Two patients had localized pocket infections, and were managed with antibiotics for a period of more than two weeks...
