OBJECTIVES: The aim of this study was to perform a systematic review and meta-analysis to estimate the normal ranges of magnetic resonance imaging (MRI)-based feature tracking (FT) and to identify sources of variations. Similar analyses were also performed for strain encoding, displacement encoding with stimulated echoes, and myocardial tagging. BACKGROUND: MRI-FT is a novel technique for quantification of myocardial deformation using MRI cine images. However, the reported 95% confidence intervals (CIs) from the 2 largest studies have no overlaps...

The present paper evaluates the association between Energy Drinks (EDs) and occurrence of atrial fibrillation (AF) in young people. Data from three clinical cases of AF after EDs consumption are reported. All patients presented with palpitations, nausea and anxiety. ECG showed AF with high ventricular response (135-170 bpm range frequency). Anamnestic record reported a high consumption of EDs during the previous 8 h from the onset of AF. In one case ED was associated with a moderate quantity of alcohol. Patients were successfully cardioverted both spontaneously and after pharmacological treatment...

Systemic lupus erythematosus (SLE) is a chronic autoimmune inflammatory disease which follows a relapsing and remitting course that can manifest in any organ system. While classic manifestations consist of arthralgia, myalgia, frank arthritis, a malar rash and renal failure to name a few, cardiac tamponade, however, is a far less common and far more dangerous presentation. We highlight the case of a 61year-old male with complaints of acute onset shortness of breath and generalized body aches associated with a fever and chills in the ER...

Syncope is a common and a typically benign clinical problem in children and adolescents. The majority of tests ordered in otherwise healthy pediatric patients presenting with syncope have low diagnostic yield. This study quantifies testing and corresponding patient charges in a group of pediatric patients presenting for outpatient evaluation for syncope. Patients seen between 3/2011 and 4/2013 in the multi-disciplinary Syncope Clinic at Cincinnati Children's Hospital Medical Center were enrolled in a registry which was reviewed for patient information...

INTRODUCTION: Monensin is a veterinary antibiotic with a narrow therapeutic window that has led to lethal intoxication in many animal species. Only two prior cases of human toxicity have been reported, both fatal. We present the first case of survival from severe toxicity following monensin ingestion. CASE: A 58-year-old man presented with 8 days of vomiting and abdominal pain. Due to delusions of central nervous system toxoplasmosis, he ingested 300 mg of monensin...

We report a 63-year-old female with hypertension, hyperlipidemia, and prior pacemaker insertion for atrial fibrillation with symptomatic bradycardia, who was admitted with substernal chest pressure and diaphoresis. Her electrocardiogram revealed atrial fibrillation with demand ventricular pacing and her cardiac biomarkers were negative for acute coronary syndrome. Echocardiogram revealed normal left ventricular systolic function and normal aortic root diameter. Coronary angiography revealed 60-70% obtuse marginal lesion, otherwise mild disease...

Rationale and key points Brain natriuretic peptide is a chemical secreted when the heart is under strain. It is sampled by a blood test. This article informs nurses about how brain natriuretic peptide can be used as a diagnostic and prognostic marker for patients with cardiac conditions. » A brain natriuretic peptide level within the normal range in a patient who is not receiving treatment, almost certainly rules out a significant cardiac condition. » An elevated brain natriuretic peptide level suggests an active cardiac condition and further investigations are indicated, usually an electrocardiogram and echocardiogram...

OBJECTIVES: In mothers with pre-gestational or gestational diabetes, abnormal arterial stiffness (stiffer arteries) has been reported. The impact of abnormal maternal arterial stiffness on fetal placental and cardiovascular physiology is unknown. The purpose of the study was to determine the impact of maternal diabetes on maternal arterial stiffness and the association with fetal cardiovascular physiology as measured by fetal echocardiography. METHODS: Between December 2013 and January 2017 we conducted a prospective study on diabetic (otherwise healthy) and non-diabetic, healthy pregnant mothers (at 20-28 gestational weeks and 18-40 years of age) who had a normal fetal cardiac echocardiogram and obstetric ultrasound...

Although accurate and robust estimations of the deforming cardiac geometry and kinematics from cine tomographic medical image sequences remain a technical challenge, they have significant clinical value. Traditionally, boundary or volumetric segmentation and motion estimation problems are considered as two sequential steps, even though the order of these processes can be different. In this paper, we present an integrated, spatiotemporal strategy for the simultaneous joint recovery of these two ill-posed problems...

In a neonate with bradycardia and hypoxia, and clinical concern for critical congenital heart disease (CCHD), highly unusual ECG findings were present. These included a flatline Lead 1, and identical Leads 2, 3, and AVF. These abnormalities were due to bilateral arm to leg lead exchanges and not to heart disease. Complete cardiac workup including echocardiogram was normal.

BACKGROUND: Surgical repair of isolated congenital tricuspid valve (TV) disease is rare with no well-defined indication and outcomes. Moreover, the role of right ventricle (RV) in this context has not yet been investigated. OBJECTIVES: We sought to assess the impact of congenital TV repair on cardiac remodelling and clinical-functional status and the importance of the RV function in an adult congenital heart disease (ACHD) population. METHODS AND RESULTS: From January 2005 to December 2015, 304 patients underwent TV surgery in our centre...

BACKGROUND: Echocardiography is often used in the evaluation of pediatric chest pain, but the incidence of cardiac pathology is low. In 2014, the American College of Cardiology published appropriate use criteria (AUC) for echocardiography including recommendations for pediatric chest pain. We evaluated the frequency and diagnostic yield of echocardiograms performed for each AUC indication and cost associated with echocardiograms performed for indications meeting the "rarely appropriate" criteria...

INTRODUCTION: While acute myocardial infarction  (AMI) mostly is a disease of the elderly it also affects younger individuals, often with serious consequenses. In 1980-1984 a study was carried out on the incidence, risk factors, infarct location and distribution of atherosclerosis among Icelanders forty years and younger with AMI. Here we present the results of a similar study carried out for the five year period 2005-2009. MATERIALS AND METHODS: Medical and autopsy records of all individuals, forty years and younger, diagnosed with AMI (I21 in ICD-10) at Landspitali, National University Hospital 2005-2009, or suffering sudden cardiac death in Iceland during the same period were reviewed...

Total anomalous pulmonary venous return (TAPVR), also known as total anomalous pulmonary venous connection, is a congenital cardiovascular malformation that presents itself in the neonatal period, with cyanosis and tachypnea. There are 4 types of TAPVR with the mixed type being the least common. Any type of TAPVR may be associated with obstruction as result of flow redirection through the liver parenchyma before it may return to the heart, but infracardiac is the most common one. We report a case of a 10-hour-old female, with a mixed (cardiac and infracardiac) TAVPR with obstruction, that showed drainage to the coronary sinus and the portal vein, as the other classic findings in TAVPR, made with computed tomography angiography and echocardiogram...

BACKGROUND: It has long been established that cardiotoxicity occurs as a result of exposure to certain chemotherapeutics, particularly anthracyclines. Historically, clinicians equate cardiotoxicity with a poor prognosis, in a small percentage of patients and deem long-term surveillance as optional. Emerging evidence suggests that anthracycline cardiotoxicity (ACT) is a life-long risk with an incidence approaching 20%. METHODS: Participants were identified via the Haematology-Oncology (HO) database at the Royal Children's Hospital, Melbourne...

Muscular dystrophies are a group of genetic disorders characterized by muscle degeneration and consequent substitution by fat and fibrous tissue. Cardiac involvement is an almost constant feature in a great part of these diseases, as both primary myocardial involvement and secondary involvement due to respiratory insufficiency, pulmonary hypertension or reduced mobility. Primary myocardial involvement usually begins more precociously compared to the secondary involvement. In fact the first signs of cardiomyopathy can be observed in the first decade of life in muscular dystrophies with childhood onset and later in adult form of muscular dystrophies as myotonic dystrophy type 1...

Rat models have assumed an increasingly important role in cardiac research. However, a detailed profile of regional cardiac mechanics, such as strains and torsion, is lacking for rats. We hypothesized that healthy rat left ventricles (LVs) exhibit regional differences in cardiac mechanics, which are part of normal function. In this study, images of the LV were obtained with 3D cine displacement encoding with stimulated echoes (DENSE) cardiovascular magnetic resonance in 10 healthy rats. To evaluate regional cardiac mechanics, the LV was divided into basal, mid-ventricular, and apical regions...

Recent advances in cancer treatment and research have greatly improved survival rates for patients with cancer. However, many of these cancer survivors are developing cardiac disease-most commonly heart failure as a result of this treatment. Certain chemotherapeutic agents, including anthracyclines and trastuzumab, have been linked to cardiotoxicity-induced cardiomyopathy in cancer patients. It has been reported as early as during infusion and as late as several years following treatment. Radiation therapy, particularly to the left breast, has also been linked to cardiac disease...
