Reflected hemodynamic waves influence the pattern of Doppler ultrasound waveforms along the umbilical arteries.

Am J Physiol Heart Circ Physiol 2019 Feb 22. Epub 2019 Feb 22.

Hospital for Sick Children / University of TOronto, Canada.

The pulsatile pattern of blood motion measured by Doppler ultrasound within the umbilical artery is known to contain useful diagnostic information and is widely used to monitor pregnancies at risk of fetal growth restriction or stillbirth. Animal studies have identified reflected pressure waves travelling counter to the direction of blood flow as an important factor in the shape of these waveforms. In the present study, we establish a method to measure reflected waves in the human umbilical artery and assess their influence on blood velocity pulsation. Read More

Transesophageal Echocardiography During Cardiopulmonary Resuscitation Is Associated With Shorter Compression Pauses Compared With Transthoracic Echocardiography.

Ann Emerg Med 2019 Feb 14. Epub 2019 Feb 14.

Division of Emergency Medicine, University of Utah School of Medicine, Salt Lake City, UT; Salt Lake City Fire Department, Salt Lake City, UT.

Study Objective: Point-of-care ultrasonography provides diagnostic information in addition to visual pulse checks during cardiopulmonary resuscitation (CPR). The most commonly used modality, transthoracic echocardiography, has unfortunately been repeatedly associated with prolonged pauses in chest compressions, which correlate with worsened neurologic outcomes. Unlike transthoracic echocardiography, transesophageal echocardiography does not require cessation of compressions for adequate imaging and provides the diagnostic benefit of point-of-care ultrasonography.

Three-Dimensional Echographic Evaluation of Carotid Artery Disease.

J Cardiovasc Echogr 2018 Oct-Dec;28(4):218-227

Department of Translational Research and New Technologies in Medicine and Surgery, Pisa University, Pisa, Italy.

The introduction of three-dimensional echography (3D echo) in vascular field is not recent, but it still remains a seldom-used technique because of the costs of ultrasound probe and the need of dedicated laboratories. Therefore, despite significant prognostic implications, the high diagnostic accuracy in plaque definition, and the relative ease of use, 3D echo in vascular field is a niche technique. The purpose of this review is mainly clinical and intends to demonstrate the potential strength of a 3D approach, including technical aspects, in order to present to clinicians and imagers the appealing aspects of a noninvasive and radiation-free methodology with relevant diagnostic and prognostic correlates in the assessment of carotid atherosclerosis.

Swiss Med Wkly 2019 Feb 11;149:w20014. Epub 2019 Feb 11.

Cardiology Department, University Hospital Basel, University of Basel, Switzerland.

Patient tailored diagnosis and risk stratification in patients with suspected or known coronary artery disease (CAD) are pivotal. At present, cardiac imaging modalities provide the possibility to evaluate the whole ischaemic cascade noninvasively. In asymptomatic patients, the evaluation of the calcium score may be beneficial and also guide the individual preventive strategy. Read More

Acta Cardiol 2019 Feb 11:1-9. Epub 2019 Feb 11.

a Department of Cardiology , CHU UCL Namur , site Godinne , Yvoir , Belgium.

A strong family history of early-onset coronary artery disease (CAD) may represent a substantial predictor of enhanced development of subclinical atherosclerosis in a sibling population. In this population, standard cardiovascular (CV) risk assessment could be underrated with the predictive capacity of the Framingham Risk Score. At present, cardiac computed tomography (CT) provides a high diagnostic performance for the detection of coronary atherosclerosis. Read More

Feasibility of Cardiac Magnetic Resonance Wideband Protocol in Patients With Implantable Cardioverter Defibrillators and Its Utility for Defining Scar.

Am J Cardiol 2019 Jan 31. Epub 2019 Jan 31.

University of Chicago Medical Center, Chicago, Illinois. Electronic address:

Implantable cardioverter defibrillators (ICDs) have been a relative contraindication to cardiovascular magnetic resonance imaging. Although cardiovascular magnetic resonance provides valuable information regarding scar in patients with ventricular arrhythmias or cardiomyopathy, ICDs in these patients frequently cause artifacts hindering accurate interpretation of both cine and late gadolinium enhancement (LGE) images. We sought to quantify the frequency and severity of artifact on LGE images and assess whether a modified wideband LGE protocol could improve the diagnostic yield of scar identification in agreement with invasive electroanatomic mapping (EAM).
