Article Synopsis
- The study investigates the effects of moderate and severe aortic stenosis (AS) on the function of the right ventricle (RV) using a detailed tissue Doppler imaging approach to assess RV deformation.
- It compares 50 patients with AS to 25 normal control subjects, measuring several parameters including systolic pulmonary artery pressure and myocardial performance index.
- Findings indicate that patients with AS exhibit significantly altered RV function metrics, highlighting the need for focused RV analysis in echocardiographic assessments of AS severity.

Article Synopsis
- Two cases of elderly patients were admitted to the hospital with heart issues: a 72-year-old male with a suspect pulmonary valve tumor and a 74-year-old female with angina and known coronary artery disease.
- Both patients were evaluated using echocardiography, which indicated potential tumors, and coronary angiography revealed significant heart disease requiring different treatment approaches.
- Surgery was recommended for the male patient due to his complex condition, while the female patient was treated with a non-surgical procedure for her artery blockage, highlighting the need for individualized therapy and the use of echocardiography for tumor detection.

Purpose The study compares the feasibility of the quantitative volumetric and semi-quantitative approach for quantification of chronic aortic regurgitation (AR) using different imaging modalities. Methods Left ventricular (LV) volumes, regurgitant volumes (RVol) and regurgitant fractions (RF) were assessed retrospectively by 2D, 3D echocardiography and cMRI in 55 chronic AR patients. Semi-quantitative parameters were assessed by 2D echocardiography.

- The study examines changes in blood flow and fluid balance in patients on long-term haemodialysis, focusing on various biomarkers and imaging techniques before and after treatment.
- Key findings indicate that levels of copeptin and MR-proANP are notably affected by haemodialysis, with copeptin showing a significant inverse relationship with treatment adequacy and fluid metrics, while NT-proBNP levels remain elevated pre-treatment.
- The research highlights the complexity of interpreting biomarker results in patients with kidney issues, emphasizing the need for considering individual health factors and other clinical data for cardiovascular risk assessment.
The aim of the present study was to find out whether early cardiac changes in patients receiving chemotherapy can be detected by the conventional and deformation parameters of 2D and 3D echocardiography. Twenty-five healthy subjects with normal regional left ventricular function (group 1) and 25 patients receiving chemotherapy (group 2) underwent 2D and 3D transthoracic echocardiography (Toshiba Artida Medical System). All patients (group 2) were examined before and during cardiotoxic chemotherapy at a 3-month follow-up.

- * The research involved 97 patients and measured various parameters of the RCA, finding that both echocardiographic methods could visualize the RCA and detect narrowing, but 2D echocardiography showed better sensitivity and specificity than 3D.
- * Despite CA being the gold standard for identifying coronary artery issues, the findings suggest that using echocardiography could allow for non-invasive detection of RCA problems before needing CA, provided the image quality is adequate.
The aim of this study was to test the feasibility of the visualisation of 3D4D coronary flow in detectable segments of coronary arteries. Regarding the feasibility of this new approach, the hypothesis was proposed that the flow signals of the course of detectable coronary arteries can be better visualised by 3D4D echocardiography than by the conventional 2D approach. A total of 30 consecutive patients with sinus rhythm, in whom the distal left anterior descending artery (LAD) was visualised by 2D colour-coded Doppler echocardiography, were selected for 3D4D scanning procedures.

Methods And Results: Standardized apical views were acquired in 30 healthy subjects and 15 patients with left ventricular systolic dysfunction using 2D echocardiography. Longitudinal peak systolic strain (PSS), longitudinal peak systolic strain rate (PSSR), postsystolic index (PSI), peak longitudinal (PLD), and peak transverse displacement (PTD) were determined by 2D speckle tracking to analyze the impact of the tracking area width on global and regional myocardial wall motion and deformation parameters.
