REVIEW
Megan Brenner, Christopher Hicks
A standardized approach should be used with a patient with abdominal trauma, including primary and secondary surveys, followed by additional diagnostic testing as indicated. Specific factors can make the diagnosis of serious abdominal trauma challenging, particularly in the face of multiple and severe injuries, unknown mechanism of injury, altered mental status, and impending or complete cardiac arrest. Advances in technology in diagnosis and/or treatment with ultrasound, helical computed tomography, and resuscitative endovascular balloon occlusion of the aorta (REBOA) have significantly advanced trauma care, and are still the focus of current and ongoing investigations...

Contrast-enhanced ultrasound (CEUS) is an emerging technology with no known nephrotoxicity. CEUS has been utilized in cardiac and abdominal imaging for decades in Asia and Europe and has recently received greater attention in the United States with its approval for characterization of indeterminate liver lesions. Emerging data suggest that CEUS has potential as a diagnostic imaging tool among individuals who have contraindications to CT and MRI. Few nephrologists are aware of CEUS and even fewer are aware of its potential applications among individuals with kidney disease...

BACKGROUND: Pulmonary embolism can be difficult to diagnose, particularly in those who are hemodynamically unstable and cannot be imaged to confirm the diagnosis. Echocardiography can allow for rapid assessment of patients in shock, but requires adequate transthoracic windows to obtain clinically useful information. Emergency physician-performed transesophageal echocardiography (TEE) may be a useful tool when transthoracic echocardiography fails. CASE REPORT: An 86-year-old woman presented to the emergency department after a fall at home...

OBJECTIVES: Prenatal diagnosis of complex congenital heart disease (CHD) during routine obstetric ultrasound (US) examinations improves postnatal outcomes, but sensitivity is low (<40%). Our objective was to improve our prenatal detection of complex CHD with implementation of a specific screening protocol. METHODS: From January 2003 to December 2013, 506 consecutive confirmed cases of complex CHD in the province of Manitoba, Canada, were analyzed to compare the sensitivity and positive predictive value of prenatal US detection of complex CHD before and after the introduction of a novel prenatal screening protocol...

AIMS: There is little evidence-based therapy existing for acute heart failure (AHF), hospitalizations are lengthy and expensive, and optimal monitoring of AHF patients during in-hospital treatment is poorly defined. We evaluated a rapid cardiothoracic ultrasound (CaTUS) protocol, combining focused echocardiographic evaluation of cardiac filling pressures, that is, medial E/e' and inferior vena cava index, with lung ultrasound (LUS) for guiding treatment in hospitalized AHF patients. METHODS AND RESULTS: We enrolled 20 consecutive patients hospitalized for AHF, whose in-hospital treatment was guided using the CaTUS protocol according to a pre-specified treatment protocol targeting resolution of pulmonary congestion on LUS and lowering cardiac filling pressures...

Point-of-care ultrasound (POCUS) is a widely used tool in critical care areas, allowing for the performance of accurate diagnoses and thus enhancing the decision-making process. Every major organ or system can be safely evaluated with POCUS. In that respect, the utility of POCUS in cardiac arrest is gaining interest. In this article, we will review the actual role of ultrasound in cardiac arrest and the main POCUS protocols focused to this scenario as well as discuss the potential role of POCUS in monitoring the efficacy of the chest compressions...

BACKGROUND: Several authors have presented cardiac phantoms to mimic the particularities of the heart, making it suitable for medical training and surgical planning. Although the initial models were mainly focused on the ventricles, personalized phantoms of the atria were recently presented. However, such models are typically rigid, the atrial wall is not realistic and they are not compatible with ultrasound (US), being sub-optimal for planning/training of several interventions. METHODS: In this work, we propose a strategy to construct a patient-specific atrial model...

BACKGROUND: The European Association of Cardiology (ESC) Guidelines on the diagnosis and treatment of acute heart failure (AHF) indicate prompt therapy initiation and performance of relevant investigations as paramount. Specifically, echocardiography prior to treatment is advocated only with hemodynamic instability, and the evaluation of clinical signs of peripheral perfusion and congestion is suggested as guidance for early interventions. Given the growing body of evidence on the diagnostic/monitoring capabilities of bedside ultrasound (including focused cardiac ultrasound, comprehensive echocardiography, lung ultrasound), we discuss the potential benefit of an integrated clinical/ultrasound approach at the very early stages of acute heart failure...

This paper presents a vector flow imaging (VFI) method for the integration of quantitative blood flow imaging in portable ultrasound systems. The method combines directional transverse oscillation (TO) and synthetic aperture sequential beamforming (SASB) to yield continuous velocity estimation in the whole imaging region. Six focused emissions are used to create a high-resolution image (HRI), and a dual-stage beamforming approach is used to lower the data throughput between the probe and the processing unit...

A method for estimating vector velocities using transverse oscillation (TO) combined with directional beamforming is presented. In directional TO (DTO), a normal focused field is emitted and the received signals are beamformed in the lateral direction transverse to the ultrasound beam to increase the amount of data for vector velocity estimation. The approach is self-calibrating as the lateral oscillation period is estimated from the directional signal through a Fourier transform to yield quantitative velocity results over a large range of depths...

Revascularization of significant Left Main Stem (LMS) disease improves clinical outcomes. This can be achieved through either Coronary Artery Bypass Grafting or Percutaneous coronary intervention. Defining a significant stenosis of the LMS can be challenging and debatable, as most data have been derived using angiographic assessment alone, with a threshold of 50% luminal stenosis used as a marker of functional significance. The use of adjunctive technologies like Intravascular Ultrasound and Fractional Flow Reserve has improved our ability to accurately assess the anatomical severity and physiological significance of coronary artery stenoses, much more so, than can be achieved through conventional angiography alone...
