There is a growing trend of using ultrasound examination of the heart as a first-line diagnostic tool for initial patient evaluation in acute settings. Focus cardiac ultrasound (FoCUS) is a standardized but restricted cardiac ultrasound examination that may be undertaken by a range of medical professionals with diverse backgrounds. The intention of this core curriculum and syllabus is to define a unifying framework for educational and training processes/programmes that should result in competence in FoCUS for various medical professionals dealing with diagnostics and treatment of cardiovascular emergencies...

BACKGROUND: Acute dyspnea is one of the main reasons for admission to Emergency Department (ED). Availability of ultraminiaturized pocket ultrasound devices (PUD) adds diagnostic power to the clinical examination. The aim of this study was to identify an integrated ultrasound approach for diagnosis of acute heart failure (acute HF), using PUD and combining evaluation from lung, heart and inferior vena cava (IVC). METHODS: We included 102 patients presenting to the ED of "Antonio Cardarelli" Hospital in Naples (Italy) for acute dyspnea (AD)...

Introduction: A functionally single cardiac ventricle seen on foetal ultrasound scan carries a guarded prognosis. The antenatal diagnosis of anomalous pulmonary venous connection (APVC) remains challenging, if there is no associated structural cardiac abnormality. Antenatally, a combination of complex cardiac anomaly with suspected isomerism should raise the possibility of associated total anomalous pulmonary venous connection (TAPVC). There needs to be a high index of suspicion for TAPVC, in functional single ventricle and suspected isomerism, as this carries a very grim outcome postnatally...

Acute decompensated heart failure (ADHF) is a common reason for admission to the hospital, and readmission is frequent. Multiple factors contribute to rehospitalizations, but inadequate assessment of volume status leading to persistent congestion is an important factor. We sought to determine if focused cardiac ultrasound (FCU) of the inferior vena cava (IVC), as a surrogate of volume status, would predict readmission of ADHF patients after index hospitalization. Patients admitted with a primary diagnosis of ADHF were prospectively enrolled...

BACKGROUND: Current transcatheter ablation of ventricular tachycardia (VT) techniques is limited in part by its invasive nature and superficial depth of ablation lesions. OBJECTIVES: This study was aimed at evaluating the feasibility of targeted ablation of cardiac tissues using high-intensity focused ultrasound (HIFU) as a potential means for non-invasive ablation of VT. METHODS: Ablation of ventricular myocardium was performed in anesthetized closed-chest dogs using a HIFU therapeutic system that is currently used clinically for ablation of human solid tumors...

PURPOSE: High intensity focused ultrasound (HIFU) can non-invasively treat tumors with minimal or no damage to intervening tissues. While continuous-wave HIFU thermally ablates target tissue, the effect of hundreds of microsecond-long pulsed sonications is examined in this work. The objective of this study was to characterize sonication parameter-dependent thermomechanical bioeffects to provide the foundation for future preclinical studies and facilitate clinical translation. METHODS AND MATERIALS: Acoustic power, number of cycles/pulse, sonication time, and pulse repetition frequency (PRF) were varied on a clinical magnetic resonance imaging (MRI) - guided HIFU (MR-HIFU) system...

Shock in newborn infants has unique etiopathologic origins that require careful assessment to direct specific interventions. Early diagnosis is key to successful management. Unlike adults and pediatric patients, shock in newborn infants is often recognized in the uncompensated phase by the presence of hypotension, which may be too late. The routine methods of evaluation used in the adult and pediatric population are often invasive and less feasible. We aim to discuss the pathophysiology in shock in newborn infants, including the transitional changes at birth and unique features that contribute to the challenges in early identification...

Functional echocardiography has become an invaluable tool in the pediatric and neonatal intensive care unit. "Point-of-care," "target," or "focus" echocardiography allows bedside cardiac ultrasound evaluation of the hemodynamic status of the patient, helps in directing treatment, thus improves patients care. In order to be able to perform functional echocardiography, it is essential to understand the principles of ultrasound, to know the echocardiographic equipment and settings necessary to acquire the images...

INTRODUCTION: Focused cardiac ultrasound can potentially identify reversible causes of cardiac arrest during advanced life support (ALS), but data on the timing of image acquisition are lacking. This study aimed to compare the quality of images obtained during rhythm analysis, bag-mask ventilations, and chest compressions. METHODS: Adult patients in cardiac arrest were prospectively included during 23 months at a Danish community hospital. Physicians who had completed basic ultrasound training performed subcostal focused cardiac ultrasound during rhythm analysis, bag-mask ventilations, and chest compressions...

BACKGROUND: Image-guided high intensity focused ultrasound has been used as an extracorporeal cardiac pacing tool and to enhance homing of stem cells to targeted tissues. However, molecular changes in the myocardium after sonication have not been widely investigated. Magnetic-resonance (MR)-guided pulsed focused ultrasound (pFUS) was targeted to the rat myocardium over a range of pressures and the microenvironmental and histological effects were evaluated over time. METHODS: Eight-to-ten-week-old Sprague-Dawley rats received T2-weighted MR images to target pFUS to the left ventricular and septum without cardiac or respiratory gating...

Critically ill patients require close hemodynamic monitoring to titrate treatment on a regular basis. It allows administering fluid with parsimony and adjusting inotropes and vasoactive drugs when necessary. Although invasive monitoring is considered as the reference method, non-invasive monitoring presents the obvious advantage of being associated with fewer complications, at the expanse of accuracy, precision, and step-response change. A great many methods and devices are now used over the world, and this article focuses on several of them, providing with a brief review of related underlying physical principles and validation articles analysis...

Hip fracture surgery is common, usually occurs in elderly patients who have multiple comorbidities, and is associated with high morbidity and mortality. Pre-operative focused cardiac ultrasound can alter diagnosis and management, but its impact on outcome remains uncertain. This pilot study assessed feasibility and group separation for a proposed large randomised clinical trial of the impact of pre-operative focused cardiac ultrasound on patient outcome after hip fracture surgery. Adult patients requiring hip fracture surgery in four teaching hospitals in Australia were randomly allocated to receive focused cardiac ultrasound before surgery or not...
