P2.9 A NOVEL SPECKLE TRACKING TECHNIQUE FOR INVESTIGATING REGIONAL MOTION OF THE CAROTID WALL: SPATIO-TEMPORAL VARIATION IN DISTENSION ASSOCIATES WITH PRESENCE OF CALCIFIED PLAQUE

Artery Research, 2015
Background: Arterial calcification may lead to regional variation in distension imposing stresses on the arterial wall that predispose to plaque rupture.

Defining a positive circumferential resection margin in oesophageal cancer and its implications for adjuvant treatment [PDF]

, 2013
A positive circumferential resection margin (CRM) has been associated with a poorer prognosis in oesophageal and oesophagogastric junctional (OGJ) cancer. The College of American Pathologists defines the CRM as positive if tumour cells are present at the

Left and Right Myocardial Functionality Assessed by Two-Dimensional Speckle-Tracking Echocardiography in Cats with Restrictive Cardiomyopathy

Animals, 2021
The endomyocardial form of restrictive cardiomyopathy (EMF-RCM), a primary disorder of the myocardium, is one of the diseases with poor prognosis in cats.

Loss of base-to-apex circumferential strain gradient assessed by cardiovascular magnetic resonance in Fabry disease: relationship to T1 mapping, late gadolinium enhancement and hypertrophy

Journal of Cardiovascular Magnetic Resonance, 2019
Cardiac involvement is common and is the leading cause of mortality in Fabry disease (FD). We explored the association between cardiovascular magnetic resonance (CMR) myocardial strain, T1 mapping, late gadolinium enhancement (LGE) and left ventricular ...

Left ventricular short-axis systolic function changes in patients with hypertrophic cardiomyopathy detected by two-dimensional speckle tracking imaging

BMC Cardiovascular Disorders, 2018
Background Hypertrophic cardiomyopathy (HCM) is a genetic disease was characterised by left ventricular hypertrophy (LVH), myocardial fibrosis, fiber disarray. The short-axis systolic function is important in left ventricle function.

Assessment of the regional distribution of normalized circumferential strain in the thoracic and abdominal aorta using DENSE cardiovascular magnetic resonance

Journal of Cardiovascular Magnetic Resonance, 2019
BackgroundDisplacement Encoding with Stimulated Echoes (DENSE) cardiovascular magnetic resonance (CMR) of the aortic wall offers the potential to improve patient-specific diagnostics and prognostics of diverse aortopathies by quantifying regionally ...

Normal range of myocardial layer-specific strain using two-dimensional speckle tracking echocardiography. [PDF]

PLoS ONE, 2017
Newer 2D strain software has a potential to assess layer-specific strain. However, normal reference values for layer-specific strain have not been established.

Immediate of Impact Prosthetic Graft Replacement of the Ascending Aorta on Circumferential Strain in the Descending Aorta.

European Journal of Vascular and Endovascular Surgery, 2019
OBJECTIVES Prosthetic replacement of the ascending aorta (AA) can potentially modify energy propagation to the distal aorta and contribute to adverse aortic remodelling.
