BACKGROUND: When a patient arrives at the emergency department (ED) presenting with symptoms of acute decompensated heart failure (ADHF), it is possible to reach a definitive diagnosis through many different venues, including medical history, physical examination, echocardiography, chest X-ray, and B-type natriuretic peptide (BNP) levels. Point-of-care ultrasound (POCUS) has become a mainstream tool for diagnosis and treatment in the field of emergency medicine, as well as in various other departments in the hospital setting...

OBJECTIVES: The purpose of this study was to use direct cardiac resynchronization therapy (CRT)-paced contractility (dP/dt-max) response as a pre-implantation evaluation among patients with congenital heart disease (CHD) and follow clinical parameters and contractility indexes after CRT implantation. BACKGROUND: Patients with CHD often develop early heart failure with few therapeutic options, leading to heart transplantation (HT). Unfortunately, guidelines for CRT do not apply, and function evaluations by cardiac ultrasound are often inaccurate among CHD anatomies...

BACKGROUND/AIMS: MicroRNAs (miRNAs) can be used as biomarkers for cardiovascular diseases, especially for heart failure. However, there are few reports on serum exosomal miRNA biomarkers in patients with acute heart failure (AHF) due to Dilated cardiomyopathy (DCM). METHODS: We analyzed 3 different serum exosomal miRNAs (exo-miR-92b-5p, exo-miR-192-5p, and exo-miR-320a) in 43 patients with DCM-AHF and 34 healthy volunteers as a control group (CG) by using exosome separation followed by a quantitative reverse-transcript PCR assay...

REVIEW
Graham J Burton, Eric Jauniaux
The placenta is the largest fetal organ, and toward the end of pregnancy the umbilical circulation receives at least 40% of the biventricular cardiac output. It is not surprising, therefore, that there are likely to be close haemodynamic links between the development of the placenta and the fetal heart. Development of the placenta is precocious, and in advance of that of the fetus. The placenta undergoes considerable remodeling at the end of the first trimester of pregnancy, and its vasculature is capable of adapting to environmental conditions and to variations in the blood supply received from the mother...

Pulmonary artery anastomosis stenosis is a rare cause of right ventricular failure after orthotopic heart transplantation. In this case report, direct ultrasound of the pulmonary artery helped diagnose stenosis at a location not visible on transesophageal echocardiography or even with standard epicardial ultrasound views. It is important to evaluate all vascular anastomoses after heart or lung transplantation because surgical revision of these lesions is facile, but if left undiagnosed, significant morbidity or mortality is likely...

CLINICIAN'S CAPSULE What is known about the topic? Current diagnostic tools for heart failure in the emergency department (ED) have limited accuracy and often lead to delays in management. What did this study ask? What is the accuracy of early bedside lung ultrasound in the diagnosis of acute decompensated heart failure? What did this study find? This meta-analysis found that the sensitivity and specificity of bedside lung US in ADHF is 82.5% and 83.6%, respectively. Why does this study matter to clinicians? The implementation of early bedside lung US in the ED may lead to more accurate and timely diagnoses of ADHF...

BACKGROUND: Diagnosis and management of patients presenting with acute dyspnea is one of the major challenges for physicians in emergency department (ED). A correct diagnosis is frequently delayed and difficult to ascertain, and clinical uncertainty is common, explaining the need for rapid diagnosis and a management plan. The primary aim of our study is to assess a diagnostic strategy using multiorgan point of care ultrasonography (USG) to differentiate patients presenting with acute dyspnea to ED into different diagnostic categories for timely management in a resource-limited setting...

Background: Hepatic fibrosis in patients with non-alcoholic fatty liver disease (NAFLD) independently predicts mortality. Given liver biopsy's invasive nature, non-invasive method to assess hepatic steatosis and fibrosis provides NAFLD risk stratification algorithm in clinical practice. NAFLD fibrosis score (NFS) is simple and non-invasive predictive model recommended by American Association for the Study of Liver Disease (AASLD) Guideline to identify patients with NAFLD with fibrosis risk...

Intraoperative pneumothorax during general anesthesia is a dangerous event. It is a possible cause of sudden intraoperative hypoxia, which can be critical especially in high-risk patients such as those with end-stage heart failure. Early diagnosis and effective treatment are essential. We describe the case of a pneumothorax during cardiac transplantation, diagnosed by ultrasound and immediately treated. A good skill in lung ultrasound is advantageous in the management of intraoperative hypoxia, particularly for prompt diagnosis of pneumothorax...

BACKGROUND: Prior studies have shown that both heart failure (HF) and atrial fibrillation (AF) are factors that impact left atrial function and structure. However, right atrial (RA) function measured as RA emptying fraction (RAEF) on echocardiography has not been analyzed systematically in a chronic HF population. The aim of this study was to assess RA volume index (RAVI) and RAEF in patients with chronic HF and patients with hypertension (HTN) and to relate these findings to other cardiopulmonary ultrasound parameters and 12-month outcomes...

The use of conventional echocardiography in the intensive care unit (ICU) is today established to assess left and right ventricular systolic function, for preload determination and procedural guidance. Next step in ICU echocardiography could be the use of novel ultrasound techniques such as strain echocardiography to assist in the management of patients with acute coronary syndrome, heart failure, or pulmonary embolism. This review has gathered the available evidence supporting the incremental value of strain in the diagnostic workup of cardiac diseases treated in ICU...

Lung ultrasound (LUS) is a largely employed diagnostic tool but an operational protocol for implementation has never been proposed. The lack of standardization clearly introduces variability in LUS results. We enrolled adult patients presenting for acute dyspnea with a clinical suspect of etiology related to heart failure. We calculated agreement among four providers in assessing B-lines. We varied probes, depth, evaluation time and scanning areas and we estimated the importance of each factors on B-lines assessment...

BACKGROUND: Cardiac allograft vasculopathy (CAV) is a leading cause of graft failure and death after heart transplantation. Absolute myocardial blood flow (MBF) quantification using rubidium 82 (Rb-82) positron emission tomography (PET) could enable evaluation of diagnostically challenging diffuse epicardial and microvascular disease in CAV. OBJECTIVES: The authors aimed to evaluate Rb-82 PET detection of CAV. METHODS: Consecutive transplant recipients undergoing coronary angiography were prospectively evaluated with PET, multivessel intravascular ultrasound (IVUS), and intracoronary hemodynamics...
