Pulmonary arterial hypertension is a progressive disease that culminates in right heart failure and death. Prostacyclin(PGI2) and its derivatives are effective treatments for PAH when administered as continuous parenteral infusions. This treatment paradigm requires medical sophistication, and patients are at risk for complications from an indewelling catheter; drug interruptions may result in rebound pulmonary hypertension and death. We hypothesized that the salivary gland can be repurposed into an endogenous production site for circulating PGI2 through the expression of a fusion protein embodying cyclooxygenase-1(Cox1) and prostacyclin synthase(PGIS) domains...

BACKGROUND: Cardiac rhabdomyoma (CRs) are the most common primary tumour of the heart in infants and children. Usually are multiple and, basing on the location can cause a haemodynamic disturbance, dysrhythmias or heart failure during the fetal and early postnatal period. CRs have a natural history of spontaneous regression and are closely associated with tuberous sclerosis complex (TSC). It has an association with tuberous sclerosis (TS), and in those, the tumour may regress and disappear completely, or remain consistent in size...

OBJECTIVE: Heart failure is a major cause of disease burden in sub-Saharan Africa (SSA). There is an urgent need for better strategies for heart failure management in this region. However, there is little information on the capacity to diagnose and treat heart failure in SSA. We aim to provide a better understanding of the capacity to diagnose and treat heart failure in Kenya and Uganda to inform policy planning and interventions. METHODS: We analysed data from a nationally representative survey of health facilities in Kenya and Uganda (197 health facilities in Uganda and 143 in Kenya)...

BACKGROUND: It is unclear how to optimally monitor acute heart failure (AHF) patients. We evaluated the timely interplay of cardiac filling pressures, brain natriuretic peptides (BNPs), lung ultrasound (LUS) and symptoms during AHF treatment. METHODS: We enrolled 60 patients who had been hospitalised for AHF. Patients were examined with a rapid cardiothoracic ultrasound (CaTUS) protocol, combining LUS and focused echocardiographic evaluation of cardiac filling pressures (i...

Methods and results: ─ We used LUS to study HF in a mouse model of systolic dysfunction, dilated cardiomyopathy, and in a mouse model of diastolic dysfunction, diabetic cardiomyopathy. LUS proved to be a reliable and reproducible tool to detect pulmonary congestion in mice. The combination of LUS and echocardiography allowed discriminating those mice that develop HF from those that do not, even in the presence of evident cardiac dysfunction. The study showed that LUS can be used to identify the onset of HF decompensation and to evaluate the efficacy of therapies for this syndrome...

BACKGROUND: Chronic hypertension in adults causes arterial lengthening in major arteries, but the effects of early fetal hypertension on the twin-twin transfusion syndrome (TTTS) recipient's vascular architecture remains unknown. OBJECTIVES: We hypothesize that arterial cord redundancy is related to recipient hypertension and subsequent heart failure. Our objectives were: 1) to establish a 3D color Doppler ultrasound method of measuring umbilical arterial (UA) length relative to its corresponding venous segment in the Umbilical cord using AV-angle, 2) to compare recipient AV-angle to gestational age-matched controls, and 3) to test the association of AV-angle with recipient heart failure...

AIMS: Increasing carotid intima-media thickness (CIMT) is associated with incident heart failure (HF). We investigated whether this association differs by diabetes status. METHODS: We characterized 13,590 Atherosclerosis Risk in Communities Study participants free of baseline HF into normal fasting glucose (NFG, glucose <100mg/dl), impaired fasting glucose (IFG, glucose 100-125mg/dl), and type 2 diabetes (T2D, glucose ≥126mg/dl, self-report, or use of diabetes drugs)...

Estimation of volume status is integral to heart failure (HF) management. Measurement of inferior vena cava (IVC) diameter (IVCd) by ultrasound provides a noninvasive estimate of right atrial pressures. The GE Vscan is a handheld ultrasound (HHU) device that allows for point-of-care measurements to assess volume status. We hypothesize that IVCd measurements using HHU can predict the risk of HF admission. We retrospectively analyzed a cohort of patients with HF treated in an ambulatory care setting over 17 months...

BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) is a leading cause of liver disease in developed countries. The association of NAFLD with conduction defects is unknown. The aim of our study was to find whether an association exists between conduction defects and NAFLD. METHODS: This is a case-control retrospective study of 700 patients admitted to Orange Park Medical Center, Orange Park, Florida from 2009 to 2015. Patients with a history of alcohol use, congenital heart disease, infiltrative malignancy, and myocarditis were excluded from the study...

INTRODUCTION: Diagnosing acute dyspnea is a critical action performed by emergency physicians (EP). It has been shown that ultrasound (US) can be incorporated into the work-up of the dyspneic patient; but there is little data demonstrating its effect on decision-making. We sought to examine the impact of a bedside, clinician-performed cardiopulmonary US protocol on the clinical impression of EPs evaluating dyspneic patients, and to measure the change in physician confidence with the leading diagnosis before and after US...

Pial arteriovenous (AV) fistulae have rarely been diagnosed in utero. They are characterized by one or more pial arteries flowing directly into a cortical vein without any shunt or interposed capillary bed. In the fetus and the newborn up to 2 years of age, the most common clinical manifestation is heart failure resulting from fistula overload. Later on, hydrocephalus, focal neurologic deficits, headaches, seizures, and cerebral hemorrhage are the most common manifestations. We present a case of nongalenic pial AV fistula diagnosed in the 25th week of pregnancy, which resulted in intrauterine fetal death due to congestive heart failure...

BACKGROUND: Kidney transplant candidates undergo rigorous testing prior to clearance for transplantation. Because kidney transplant candidates may be at increased risk for carotid artery stenosis because of arteriosclerosis and atherosclerosis secondary to hypertension, vascular calcification, and diabetes, carotid ultrasound is often performed with the intent of preventing a cerebrovascular accident in the perioperative or posttransplant period. To our knowledge, there has not been a study investigating the utility of screening carotid ultrasonography in pretransplant candidates...

An 8-month-old boy presents with 1 week of gradually worsening respiratory distress. After chest radiograph shows bilateral airspace opacities, he is treated for pneumonia with antibiotics and intravenous fluids. Shortly after this, he decompensates requiring intubation, followed by cardiopulmonary support with pressors and eventually extracorporeal membrane oxygenation. Bedside ultrasound then shows an additional congenital membrane in the left atrium obstructing pulmonary venous return and thought to have caused his original presentation and subsequent decompensation...

OBJECTIVES: We aimed to study whether patient-reported outcomes, measured by quality of life (QoL) and functional class, are sensitive to pleural effusion (PLE) in patients with heart failure (HF), and to study changes in QoL and functional class during follow-up of PLE. METHODS: A cohort of 62 patients from an outpatient HF clinic was included. The amount of PLE was quantified using a pocket-sized ultrasound imaging device. Self-reports of QoL and functional class were collected using the Minnesota Living with Heart Failure Questionnaire (MLHFQ) and the New York Heart Association (NYHA) functional classification...

To investigate whether metformin can improve the cardiac function through improving the mitochondrial function in model of heart failure after myocardial infarction. Male C57/BL6 mice aged about 8 weeks were selected and the anterior descending branch was ligatured to establish the heart failure model after myocardial infarction. The cardiac function was evaluated via ultrasound after 3 days to determine the modeling was successful, and the mice were randomly divided into two groups. Saline group (Saline) received the intragastric administration of normal saline for 4 weeks, and metformin group (Met) received the intragastric administration of metformin for 4 weeks...
