Aims: We have previously shown that 2-dimentional strain is not a useful tool for ruling out acute coronary syndrome (ACS) in the emergency department (ED). The aim of the present study was to determine whether in patients with suspected ACS, global longitudinal strain (GLS), measured in the ED using 2-dimensional strain imaging, can predict long-term outcome.
Methods: Long-term (median 7.
Article Synopsis
- The study analyzed the impact of image quality on two-dimensional longitudinal strain (2DLS) measurements in diagnosing acute coronary syndromes (ACS) in emergency department patients.
- Comparing high-quality (HighQ) and low-quality (LowQ) images from 605 patients, results showed that low image quality was linked to worse 2DLS outcomes and identified low-Q images as a predictor of abnormal 2DLS.
- Despite higher accuracy in HighQ images, abnormal 2DLS did not prove useful for excluding ACS in either group, highlighting limitations of 2DLS in clinical settings.
Aim: The energy loss coefficient (ELCo) has been suggested as a more accurate indicator of aortic stenosis (AS) severity as compared to transthoracic echocardiography (TTE) aortic valve area (AVA). There are little data regarding the optimal location for aortic area (Aa) measurement needed for ELCo calculation and the agreement of ELCo with direct anatomical AVA measurement. The aim of this study was to determine the optimal site of Aa measurement for calculation of the ELCo, using cardiac computed tomography angiography (CCTA) AVA planimetry as the reference standard.

- The study aimed to compare left ventricular outflow tract (LVOT) area and aortic valve area (AVA) measurements using 2D and 3D transthoracic echocardiography (TTE) alongside cardiac computed tomographic angiography (CCTA) to improve AVA estimation accuracy.
- It involved 50 patients split into two groups, assessing LVOT area and AVA with 2D TTE and then validating findings with 3D TTE and CCTA.
- Results showed that 2D TTE consistently underestimated LVOT area and AVA compared to CCTA, but applying a correction factor resulted in similar AVA measurements between both methods.
Right ventricular outflow tract systolic excursion: a novel echocardiographic parameter of right ventricular function.
Eur Heart J Cardiovasc Imaging

Aims: Right ventricular (RV) function has important prognostic and therapeutic implications. Assessment of RV function using echocardiography is challenging. The aim of this study was to evaluate a new parameter of RV function, right ventricular outflow tract systolic excursion (RVOT_SE).

Transesophageal echocardiography (TEE) can accurately delineate the LVOT. The aim of this study was to assess the accuracy and reproducibility of LVOTd measurement using transthoracic echocardiography (TTE) with harmonic imaging when compared with TEE, in both systole and diastole.
