Etiology-Discriminative Multimodal Imaging of Left Ventricular Hypertrophy and Synchrotron-Based Assessment of Microstructural Tissue Remodeling.

Front Cardiovasc Med 2021 25;8:670734. Epub 2021 May 25.

Institut d'Investigacions Biomèdiques August Pi i Sunyer, Barcelona, Spain.

Distinguishing the etiology of left ventricular hypertrophy (LVH) is clinically relevant due to patient outcomes and management. Easily obtained, echocardiography-based myocardial deformation patterns may improve standard non-invasive phenotyping, however, the relationship between deformation phenotypes and etiology-related, microstructural cardiac remodeling has not been reported. Synchrotron radiation-based X-ray phase-contrast imaging (X-PCI) can provide high resolution, three-dimensional (3D) information on myocardial microstructure. Read More

Two-dimensional transthoracic echocardiography at rest for the diagnosis, screening and management of pulmonary hypertension.

Swiss Med Wkly 2021 May 7;151:w20486. Epub 2021 Jun 7.

Cardiology Department, Lausanne University Hospital (CHUV), Lausanne, Switzerland.

Doppler echocardiography is widely used in everyday clinical practice for the detection of pulmonary hypertension (PH) in symptomatic patients and in populations particularly at risk of pulmonary arterial hypertension (PAH). It allows accurate estimation of systolic pulmonary arterial pressure but may lack precision in particular situations. In addition, echocardiography can help to distinguish between pre- and post-capillary PH and is a very good tool to evaluate right ventricular systolic function, which is of great prognostic interest in PAH.

Novel robotic TCD ultrasound with bubbles versus standard care to detect right to left shunt: Study methods.

J Neuroimaging 2021 Jun 3. Epub 2021 Jun 3.

Department of Neurology, University of Tennessee Health Science Center, Memphis, Tennessee, USA.

Background And Purpose: Right to left shunt (RLS), from patent foramen ovale (PFO) or elsewhere, is a recognized risk factor for stroke. Current standard of care for RLS diagnosis includes transthoracic echocardiography (TTE) which is insensitive, transesophageal echocardiography (TEE) which is invasive, and transcranial Doppler (TCD) which has excellent sensitivity and specificity for RLS but is heavily operator dependent and expertise is scarce. The purpose of this study was to evaluate the RLS detection rate of a novel robotic-assisted TCD (ra-TCD) to standard of care diagnostic techniques, including TTE, TEE, and TCD. Read More

J Cardiovasc Imaging 2021 Mar 15. Epub 2021 Mar 15.

Division of Cardiology, Asan Medical Center, College of Medicine, University of Ulsan, Seoul, Korea.

Diagnostic and Prognostic Accuracy of Aortic Valve Calcium Scoring in Patients With Moderate-to-Severe Aortic Stenosis.

Front Cardiovasc Med 2021 17;8:673519. Epub 2021 May 17.

Pôle de Recherche Cardiovasculaire, Institut de Recherche Expérimentale et Clinique, Université Catholique de Louvain, Brussels, Belgium.

Assessing the true severity of aortic stenosis (AS) remains a challenge, particularly when echocardiography yields discordant results. Recent European and American guidelines recommend measuring aortic valve calcium (AVC) by multidetector row computed tomography (MDCT) to improve this assessment. To define, using a standardized MDCT scanning protocol, the optimal AVC load criteria for truly severe AS in patients with concordant echocardiographic findings, to establish the ability of these criteria to predict clinical outcomes, and to investigate their ability to delineate truly severe AS in patients with discordant echocardiographic AS grading.
