A 67-year-old man was admitted to our hospital after episodes of syncope preceded by malaise and diffuse neck and chest discomfort. No family history of cardiac disease was reported. Laboratory workup was within normal limits, including D-dimers, serum troponin I and arterial blood gases. The electrocardiogram showed sinus rhythm with T-wave inversion in leads V1 to V3. Computed tomography angiography to investigate pulmonary embolism showed no abnormal findings. Transthoracic echocardiography (TTE) displayed massive enlargement of the right ventricle with intact interatrial septum and no pulmonary hypertension...

INTRODUCTION: Vasovagal syncope (VVS) is a clinical syndrome characterized by transient loss of consciousness and postural tone that is due to a temporary and spontaneously self-terminating global cerebral hypoperfusion. It is known that personality modulates the individual's sensitivity to stressors, and emotional arousal and psychologic uncertainty are conditions contributing to vasodepressor syncope. Therefore it is postulated that personality characteristics of VVS patients could have a role in the pathophysiology of VVS...

INTRODUCTION: We sought to compare three hospital cost-estimation models for patients undergoing evaluation for unexplained syncope using hospital cost data. Developing such a model would allow researchers to assess the value of novel clinical algorithms for syncope management. METHODS: We collected complete health services data, including disposition, testing, and length of stay (LOS), on 67 adult patients (age 60 years and older) who presented to the emergency department (ED) with syncope at a single hospital...

BACKGROUND: Autonomic denervation is an alternative approach for patients with symptomatic bradycardia. No consensus exists on the critical targets and end points of the procedure. The aim of this study was to identify immediate end points and critical atrial regions responsible for vagal denervation. METHODS AND RESULTS: We enrolled 14 patients (50% men; age: 34.0±13.8 years) with cardioinhibitory syncope, advanced atrioventricular block or sinus arrest, and no structural heart disease...

OBJECTIVE: To evaluate published algorithms for the identification of epilepsy cases in medical claims data using a unique linked dataset with both clinical and claims data. METHODS: Using data from a large, regional health delivery system, we identified all patients contributing biologic samples to the health system's Biobank (n = 36K). We identified all subjects with at least one diagnosis potentially consistent with epilepsy, for example, epilepsy, convulsions, syncope, or collapse, between 2014 and 2015, or who were seen at the epilepsy clinic (n = 1,217), plus a random sample of subjects with neither claims nor clinic visits (n = 435); we then performed a medical chart review in a random subsample of 1,377 to assess the epilepsy diagnosis status...

BACKGROUND: Long QT syndrome confers susceptibility to ventricular arrhythmia, predisposing to syncope, seizures, and sudden death. While rare globally, long QT syndrome is ≈15× more common in First Nations of Northern British Columbia largely because of a known mutation in KCNQ1. However, 2 large multigenerational families were affected, but negative for the known mutation. METHODS AND RESULTS: Long QT syndrome panel testing was carried out in the index case of each family, and clinical information was collected...

We present a rather unusual cause for syncope associated with atrial tachycardia. A man aged 39 years presented with an episode of syncope and narrow complex tachycardia. Further investigations, including transoesophageal echocardiography, identified cor triatriatum sinistrum (CTS), a rare congenital abnormality characterised by the atrium being divided by a fibrous membrane. Although it is rare, there has been an increase in diagnosis due to developments in diagnostic imaging techniques. Symptoms are related to the size of fenestrations within the fibrous membrane...

BACKGROUND: Ambulatory electrocardiography (ECG) monitors are often used to detect cardiac arrhythmia. For patients with symptoms, an external cardiac loop recorder will often be recommended. The improved recording capacity of newer Holter monitors and similar devices, collectively known as longterm continuous ambulatory ECG monitors, suggests that they will perform just as well as, or better than, external loop recorders. This health technology assessment aimed to evaluate the effectiveness, cost-effectiveness, and budget impact of longterm continuous ECG monitors compared with external loop recorders in detecting symptoms of cardiac arrhythmia...

Background -The Systolic Blood Pressure Intervention Trial (SPRINT) demonstrated a 27% reduction in all-cause mortality with a systolic blood-pressure (SBP) goal of <120 mmHg versus <140 mmHg among U.S. adults at high cardiovascular disease (CVD) risk but without diabetes, stroke, or heart failure. To quantify the potential benefits and risks of SPRINT intensive goal implementation, we estimated the deaths prevented and excess serious adverse events (SAEs) incurred if the SPRINT intensive SBP treatment goal was implemented in all eligible U...

BACKGROUND: The Institute of Medicine, in a 2013 report, recommended that the Vaccine Safety Datalink (VSD) expand collaborations to include more diversity in the study population. Kaiser Permanente Colorado (KPCO), an established VSD site, partnered with Denver Health (DH), an integrated safety net healthcare system, to demonstrate the feasibility of integrating DH data within the VSD. Prior to incorporating the data, we examined the identification of specific vaccine associated adverse events (VAEs) in these two distinct healthcare systems...

An 18-year-old African-American female presented with an episode of syncope. Initial investigations revealed large lung mass with invasion into right atrium along with lesions in kidneys and liver. Patient also developed superior vena cava syndrome due to lung mass. Biopsy of lung mass revealed diagnosis of composite lymphoma with involvement by primary mediastinal B-cell lymphoma (PMBCL) and classical Hodgkin lymphoma. Patient was started on dose-adjusted etoposide, prednisone, vincristine, cyclophosphamide, doxorubicin and rituximab (EPOCH-R) with complete response to treatment...

BACKGROUND: Syncope is a common reason for outpatient transthoracic echocardiography (TTE). We studied the applicability of pediatric appropriate use criteria (AUC) on initial outpatient evaluation of children (≤18 years) with syncope. METHODS: Data were obtained before (Phase I, April-September 2014) and after (Phase II, January-April 2015) the release of the AUC document from six participating pediatric cardiology centers. Site investigators determined the indication for TTE and assigned appropriateness rating based on the AUC document: Appropriate (A), May Be Appropriate (M), Rarely Appropriate (R), or "unclassifiable" (U) if it did not fit any scenario in the AUC document...

"Idiopathic" ventricular fibrillations are rare and are estimated between 5% and 10% of survivors of hospital cardiac arrest, for at least some of them have as origin, a trigger in the Purkinje fibers. Interventional therapy could be an effective, long-lasting solution for these recurrent malignant arrhythmias and should be considered.

Anterior cervical discectomy and fusion (ACDF) is a very common surgery performed globally. Although a few cases of expectorating screws or extrusion of screws into the gastrointestinal tract through esophageal perforations have previously been reported, there has not been a case reporting pharyngeal perforation and entire cervical construct extrusion in the literature to date. In this report the authors present the first case involving the extrusion of an entire cervical construct via a tear in the posterior pharyngeal wall...

Recovery from exercise refers to the time period between the end of a bout of exercise and the subsequent return to a resting or recovered state. It also refers to specific physiological processes or states, occurring after exercise, which are distinct from the physiology of either the exercising or the resting states. In this context, recovery of the cardiovascular system after exercise occurs across a period of minutes to hours, during which many characteristics of the system, even how it is controlled, are changing over time...

BACKGROUND: Dextrocardia, or right-lying heart, is an uncommon congenital heart disease in which the apex of the heart is located on the right side of chest. Persistent left superior vena cava (PLSVA) is a rare venous anomaly that is often associated with the abnormalities of cardiac transduction system. A case with combination of dextrocardia, persistent left superior vena cava, and sick sinus syndrome has not been reported. METHODS: We used different techniques including cardiac color Doppler echocardiography, 24-hour Holter monitoring, and abdominal ultrasound to make a diagnosis and treated the patient by implanting a VVI pacemaker...
