Reduced left atrial contractile strain with speckle tracking analysis predicts abnormal plasma NTproBNP in an asymptomatic community population

open access: yesCardiovascular Ultrasound, 2022
Background The left atrium (LA) is closely related to left ventricular diastolic function. Two-dimensional speckle tracking strain and strain rate (SR) imaging has been applied in the study of LA function.

Association of PET-measured myocardial flow reserve with echocardiography-estimated pulmonary artery systolic pressure in patients with hypertrophic cardiomyopathy [PDF]

open access: yes, 2019
BackgroundPulmonary hypertension (PH) is a known complication of HCM and is a strong predictor of mortality. We aim to investigate the relationship between microvascular dysfunction measured by quantitative PET and PH in HCM patients.MethodsEighty-nine ...

Echocardiography in the Chinchilla [PDF]

open access: yesJournal of Veterinary Internal Medicine, 2004
Heart disease has been described in the chinchilla and, with increasing popularity as a pet, the demand for diagnostic evaluation and treatment has increased. The goal of this study was to determine reference values for echocardiographic measurements in chinchillas and the effect of anesthesia on these measurements.

Assessment of right atrium dysfunction in patients with obstructive sleep apnea syndrome using velocity vector imaging

open access: yesCardiovascular Ultrasound, 2018
Background and Objectives This study aimed to assess the changes of RA function in patients with obstructive sleep apnea syndrome (OSAS) using velocity vector imaging (VVI) and to evaluate the application of VVI technology. Methods According to the apnea–

Three-dimensional echocardiography and 2D-3D speckle tracking imaging in chronic pulmonary hypertension. diagnostic accuracy in detecting hemodynamic signs of RV failure [PDF]

open access: yes, 2015
Background and objective. Our aim was to compare three-dimensional (3D) and 2D and 3D speckle tracking (2D-STE, 3D-STE) echocardiographic parameters with conventional right ventricular (RV) indexes in patients with chronic pulmonary hypertension (PH ...

Transesophageal echocardiography

open access: yesJournal of Ultrasonography, 2019
Transthoracic and transesophageal examinations should be considered as mutually complementary. Transesophageal echocardiography is performed in cases of a justified need to visualize structures that are poorly visible or invisible on transthoracic echocardiogram.

Abnormal Myocardial Blood Flow Reserve Observed in Cardiac Amyloidosis [PDF]

open access: yes, 2016
We performed real-time myocardial contrast echocardiography on a patient with cardiac amyloidosis and previous normal coronary angiography presenting with atypical chest pain to assess myocardial blood flow reserve (MBFR).

The Year in Echocardiography

open access: yesJournal of the American College of Cardiology, 2004
The year in echocardiography has been marked by incremental progress in our understanding of the methodology and potential applications of techniques introduced in the last few years, such as speckle tracking (STE), real-time 3-dimensional echocardiography (RT3DE), and Doppler tissue imaging (DTI).

Left ventricular systolic function evaluated by strain echocardiography and relationship with mortality in patients with severe sepsis or septic shock. a systematic review and meta-analysis [PDF]

open access: yes, 2018
Sepsis-induced myocardial dysfunction is associated with poor outcomes, but traditional measurements of systolic function such as left ventricular ejection fraction (LVEF) do not directly correlate with prognosis.
