BACKGROUND: Many patients with non-valvular atrial fibrillation (NVAF) with high risk for thromboembolic stroke and bleeding may not wish to continue long-term oral anticoagulants (OACs) to avoid bleeding complications. We aimed to investigate whether AF burden assessment by cardiovascular implantable electronic devices (CIEDs) would allow an individualised disease-guided approach for safe withdrawal of long-term OAC in high-risk patients. METHODS AND RESULTS: We studied 145 patients (age 77...

A microfluidic flow-based platform (μFP), able to stimulate platelets via exposure of shear stress patterns pertinent to cardiovascular devices and prostheses, was compared to the Hemodynamic Shearing Device (HSD)-a state-of-the-art bench-top system for exposure of platelets to defined levels and patterns of shear. Platelets were exposed to time-varying shear stress patterns in the two systems; in detail, platelets were recirculated in the μFP or stimulated in the HSD to replicate comparable exposure time...

BACKGROUND: The treatment of infected or exposed cardiac pacing and defibrillator devices is controversial. The conservative and widely accepted management calls for removal of the device and leads with immediate or delayed replacement of new components in a new site. Lead extraction carries a 2% major complication risk. In this article, we describe our experience with device salvage techniques and review the current literature. METHODS: This is a retrospective case series of consecutive patients with infected, exposed, or at-risk implanted cardiac devices that were treated with aggressive surgical debridement, local pocket irrigation, and revision...

Cardiac rhythm disorder is frequently encountered in hemodialysis patients and is often treated with a cardiovascular implantable electronic device (CIED). The conventional CIED requires placement of transvenous leads resulting in subclinical central venous stenosis, which can adversely affect the successful creation of a permanent dialysis vascular access. The technological advancement of a leadless pacemaker provides an opportunity to implement a strategy to preserve central veins in patients with chronic kidney disease...

Device infection remains a significant challenge as clinical indications for cardiovascular implantable electronic devices (CIED) therapy continue to expand beyond prevention and treatment of cardiac arrhythmias. Patients receiving CIED therapy are now older with significant comorbidities, placing them at higher risk of complications including infection. CIED infection warrants complete device removal as retention is associated with unacceptably high risk of relapse and increased mortality. However, accurate diagnosis of CIED infections remains a significant challenge and is based on a combination of findings on physical examination, microbiological and laboratory testing, and advanced imaging such as transesophageal echocardiography or positron emission tomography...

Cryptogenic ischemic stroke, defined as stroke of undetermined etiology, accounts for 7-25% of all ischemic strokes. Stroke severity is reported to be less severe than cardioembolic stroke and similar to large-artery atherosclerosis. Because its etiology is believed to be mostly an embolic type, it is often called "embolic strokes of undetermined source" (ESUS). In patients with ESUS, it is of significant importance to seek an embolic source with intensive diagnostic assessment, which mostly originates from the heart...

We performed a retrospective review of 402 consecutive patients who underwent heart transplantation at our institution between January 2009 and March 2017. A retained cardiovascular implantable electronic device (CIED) fragment was identified after transplantation in 49 of the 301 patients (16.2%) with CIED at baseline. Patients with retained fragments had leads with longer dwell times (median 2596 [1982, 3389] vs 1384 [610, 2202] days, P < .001), higher prevalence of previously abandoned leads (14.3% vs 2...

Background: Brucellosis is a bacterial infection, caused by the nonmotile gram-negative aerobic coccobacilli. The clinical manifestation of brucellosis is variable, ranging from mild disease to severe disease. The gold standard test to confirm the diagnosis of brucellosis is assaying blood, bone marrow, or other body fluids or by tissue culture. Preferred first-line treatment in adults with uncomplicated, nonlocalized disease consists of doxycycline-aminoglycoside combination. The recommended duration of treatment is 6 weeks...
