Patients' and family members' views on pacemaker reuse: An international survey.

Introduction: The reuse of cardiac implantable electronic devices may help increase access to these therapies in low- and middle-income countries (LMICs). No published data exist regarding the views of patients and family members in LMICs regarding this practice.

Methods And Results: An article questionnaire eliciting attitudes regarding pacemaker reuse was administered to ambulatory adult patients and patients' family members at outpatient clinics at Centro Nacional Cardiologia in Managua, Nicaragua, Indus Hospital in Karachi, Pakistan, Hospital Carlos Andrade Marín, and Hospital Eugenio Espejo in Quito, Ecuador, and American University of Beirut Medical Center in Beirut, Lebanon.

Digital thermography and vascular involvement in β-thalassemia intermedia.

Beta-thalassemia intermedia (β-TI) is associated with vascular dysfunction. We used digital thermal monitoring (DTM), a non-invasive tool that evaluates vascular function based on changes in fingertip temperature during and after cuff occlusion on β-TI patients. Thirty-three patients (18 years and older) were recruited in this study and divided into 3 groups: thalassemia, anemic controls, and healthy controls.

Potential Biomarkers in Atrial Fibrillation: Insight Into Their Clinical Significance.

In risk-stratifying patients with atrial fibrillation (AF), physicians rely heavily on clinical parameters that provide risk scores and determine treatment strategies. There has been increasing research on potential biomarkers in the blood that could more accurately determine both risk of complications in AF and risk of incidence of AF. This review highlights the clinical significance of 5 novel biomarkers that have been shown to be linked to AF.

Arrhythmias in Neonates and Infants at a Tertiary Care Center.

Background Limited data about arrhythmias in neonates and infants are coming out from the Middle East. Objectives To evaluate different types of arrhythmias in neonates and infants at the American University of Beirut Medical Center (AUBMC), a tertiary care center in Lebanon, with the focus on the nature of arrhythmia, treatment modalities and relation to surgery. Methods Data were collected retrospectively from the hospital records.

Genomic and Proteomic Study of the Inflammatory Pathway in Patients With Atrial Fibrillation and Cardiometabolic Syndrome.

Atrial fibrillation (AF) and cardiometabolic syndrome (CMS) have been linked to inflammation and fibrosis. However, it is still unknown which inflammatory cytokines contribute to the pathogenesis of AF. Furthermore, cardiometabolic syndrome (CMS) risk factors such as obesity, hypertension, insulin resistance/glucose intolerance are also associated with inflammation and increased level of cytokines and adipokines.

Nonbacterial Thrombotic Endocarditis and Widespread Skin Necrosis in Newly Diagnosed Lung Adenocarcinoma.

Nonbacterial thrombotic endocarditis (NBTE) is a rare entity most commonly diagnosed postmortem with rates in autopsy series ranging from 0.9 to 1.6%.

Noninvasive Cardioablation.

Stereotactic body radiotherapy uses the principle of 3-dimensional localization of a target to deliver a high dose of radiation to a precise location. The aim of this technique is to ablate tissue noninvasively. Because of its high precision and target conformity, it can deliver a high dose of radiation to a specific area in a tissue without significantly affecting nearby tissues.

Cardiac implantable electronic device infections: Observational data from a tertiary care center in Lebanon.

With increasing rates of device implantation, there is an increased recognition of device infection. We conducted a retrospective observational study in a tertiary care center in Lebanon, with data collected from medical records of patients presenting with cardiac implantable electronic device (CIED) infection from 2000 to 2017 with the purpose of identifying etiologies, risk factors and other parameters, and comparing them to available data from the rest of the world. We identified a total of 22 CIED infections.

Non-familial cardiomyopathies in Lebanon: exome sequencing results for five idiopathic cases.

Background: Cardiomyopathies affect more than 0.5% of the general population. They are associated with high risk of sudden cardiac death, which can result from either heart failure or electrical abnormalities.

Genetics of Atrial Fibrillation.

Background Atrial fibrillation ( AF ) is a common arrhythmia seen in clinical practice. Occasionally, no common risk factors are present in patients with this arrhythmia. This suggests the potential underlying role of genetic factors associated with predisposition to developing AF .

Long-term performance of a pacing lead family: A single-center experience.

Background: The performance of Abbott/St. Jude Medical (Sylmar CA) Tendril pacing leads has not been well characterized.

Objective: We sought to assess the performance of Tendril leads as compared with that of different pacing leads.

Swine Atrioventricular Node Ablation Using Stereotactic Radiosurgery: Methods and In Vivo Feasibility Investigation for Catheter-Free Ablation of Cardiac Arrhythmias.

Background: Linear accelerator-based stereotactic radiosurgery delivered to cardiac arrhythmogenic foci could be a promising catheter-free ablation modality. We tested the feasibility of in vivo atrioventricular (AV) node ablation in swine using stereotactic radiosurgery.

Methods And Results: Five Large White breed swine (weight 40-75 kg; 4 females) were studied.

Intramuscular myxoma of the tibialis anterior muscle First report in the English literature.

Intramuscular myxoma is a rare entity in itself, and while it has been described in several locations in the body, its presence in the tibialis anterior muscle has only been reported once in the literature. In this case report, we present, to our knowledge, the first case of an intramuscular myxoma in the tibialis anterior muscle in the English literature, which was successfully managed with wide surgical resection.
