How the trabeculae protrude within the left atrial appendage is the key factor affecting thrombosis in patients with atrial fibrillation
This study aimed to investigate the relationship between the condition of trabeculae protrusion and LAA thrombosis. This retrospective study consecutively selected patients diagnosed with non-valvular atrial fibrillation and prepared for radiofrequency ablation from January 2011 to May 2020. Patients were divided into the thrombus group (n  = 43), the sludge group (n = 35), and the normal group (n = 407) according to whether the thrombus or sludge was present. The trabeculae protruding angle (TPA), which was measured by the CT scans, was used to quantify the trabeculae protrusion condition. Patients’ clinical...

Left atrial strain as a predictor of left ventricular filling pressures in coronary artery disease with preserved ejection fraction: a comprehensive study with left ventricular end-diastolic and pre-atrial contraction pressures
AbstractAssessing left ventricular (LV) filling pressure (LVFP) is challenging in patients with coronary artery disease (CAD) and preserved LV ejection fraction (LVEF). We aimed to correlate left atrial strain (LAS) with two invasive complementary parameters of LVFP and compared its accuracy to other echocardiographic data to predict high LVFP.  This cross-sectional, single-center study enrolled 81 outpatients with LVEF >  50% and significant CAD from a database. Near-simultaneous echocardiography and invasive measurements of both LV end-diastolic pressure (LVEDP) and LV pre-atrial contraction (pre-A) pressure were...

Contrast-enhanced ultrasound for non-invasive differential diagnosis of unclear left atrial mass
AbstractTransthoracic and transesophageal echocardiography detected a left atrial mass attached to the intra-atrialseptum. Intravenous contrast agent ruled out atrial thrombus, sugesting a left atrial myxoma. This highlights theimportance of contrast echocardiography for differential diagnosis of left atrial findings.

Reproducibility of transthoracic 3D echocardiography in the assessment of mitral valve area in patients with rheumatic mitral stenosis: real time versus ECG-gated 3D echocardiography
Conclusion: RT3D and EG3D are equally reproducible in the assessment of MVA in patients with MS. Further measurements standardization is required to have a clinically acceptable estimations of the true 3D MVA and minimal detectable differences.

Evaluation of cardiovascular autonomic dysfunction in symptomatic post-COVID-19 patients using the heart rate variability (HRV) and detection of subtle LV dysfunction using 2D global longitudinal strain (GLS)
ConclusionOur study targeted patients experiencing prolonged symptoms after COVID-19 illness. We detected a high incidence of GLS impairment using Speckle Tracking Echocardiography (STE) and a significant prevalence of diminished HRV. HRV (especially SDNN) and GLS were found to be significantly correlated.Graphical abstract (Source: The International Journal of Cardiovascular Imaging)

Evaluating the characteristics of myocardial work by two-dimensional echocardiography during pre-eclampsia pregnancy
In conclusion, during the PE pregnancy, GWI, GCW and GWW increase, while GWW elevates more than GCW, which leads to the decrease in GWE. Moreover, the changes in MyW are associated with the hypertension grades and the poor prognosis in PE. The non-invasive manner for MyW assessment provides a new perspective on the myocardial biomechanics, cardio-metabolic conditions and pathophysiological changes in the condition of PE.

Usefulness of three-dimensional pulmonary vein-left atrium image reconstructed from non-enhanced computed tomography for atrial fibrillation ablation
This study provides clinically useful information on a detailed methodology for 3D PV-LA image reconstruction using non-enhanced CT. Non-enhanced CT 3D PV-LA images were successfully registered into the EAM system and useful for patients unsuitable for CM use. (Source: The International Journal of Cardiovascular Imaging)

Relationship between presystolic wave and subclinical left ventricular dysfunction as assessed by myocardial performance index in patients with metabolic syndrome
AbstractThe myocardial performance index (MPI) is an index that shows both systolic and diastolic functions of the ventricle. Presystolic wave (PSW) is a late diastolic wave encountered in the left ventricular outflow tract (LVOT) and is associated with increased left ventricular stiffness and decreased left ventricular compliance. In our study, MPI was compared between patients with metabolic syndrome and normal patients, and we also investigated whether PSW could predict subclinical left ventricular dysfunction (SCLVD) in patients with metabolic syndrome. A total of 119 patients, 59 with metabolic syndrome and 60 healthy...

First study demonstrating speckle tracking echocardiography has prognostic value in patients with idiopathic inflammatory myopathies
AbstractTo measure left ventricular (LV) global longitudinal strain (GLS) using speckle tracking echocardiography in idiopathic inflammatory myopathy (IIM) patients and to determine whether the LV GLS predicts outcomes in those patients. Prospective study consisted of a cross-sectional phase with 61 IIM patients and 32 individuals without IIM and longitudinal phase, in which patients were divided into two subgroups: 26 with reduced LV GLS and 35 with normal LV GLS; patients were followed for a mean of 25  months, and the occurrence of cardiovascular events and criteria for IIM activity were compared. The mean LV GLS (18.5...

Prognostic value of coronary CT angiography for the prediction of all-cause mortality and non-fatal myocardial infarction: a propensity score analysis
AbstractTo explore the relationship between comprehensive assessment of coronary atherosclerosis by coronary CT angiography (CCTA) and all-cause mortality and non-fatal myocardial infarction in the Chinese population. Sixty-three patients from the prospective long-term study who experienced major adverse cardiovascular events (MACE) during the follow-up were included. No-MACE patients were 1:1 propensity-matched. Various qualitative and quantitative CCTA parameters, such as coronary artery calcium score (CACS), high-risk plaque, coronary artery disease (CAD) severity, number of obstructive vessels, segment involvement scor...
