Background: Intima-media thickness (IMT) has been proposed as a measurement of subclinical atherosclerosis and has been associated with cardiovascular disease (CVD). Epicardial adipose tissue (EAT) is a fat depot between the pericardium and myocardium and has been associated with coronary atherosclerosis. The relationship between IMT and EAT thickness has not been reported before. We investigated the relationship between EAT thickness, IMT, CVD risk factors, and ideal cardiovascular health (CVH) metrics using subjects from the Kardiovize Brno 2030 cohort study, a random urban sample population in Central Europe...

The PECS II nerve block is a relatively new regional anesthetic technique that targets the medial and lateral pectoral nerves, as well as the lateral cutaneous branches of the intercostal nerves. It has been described for surgical cases involving the breast, as an adjunct or alternative to neuraxial or paravertebral techniques. This case report describes the first successful use of the PECS II nerve block placed using ultrasound guidance as the primary anesthetic and postoperative analgesic in a non-breast-related chest wall surgery...

Multiple studies have demonstrated the association of red cell distribution width (RDW) with the ultrasound parameters of both systolic and diastolic heart dysfunction. We aimed to further investigate the clinical associations of RDW in the setting of ST-elevation myocardial infarction (STEMI) and to comparatively evaluate its predictive properties regarding systolic and diastolic dysfunction.A total of 89 patients with STEMI were prospectively analyzed. RDW was obtained at the time of STEMI and compared to the parameters of systolic and diastolic dysfunction obtained by transthoracic heart ultrasound on the 5th through 7th day post-STEMI...

Transthoracic ultrasound has lately emerged as a useful diagnostic tool for respiratory physicians in the diagnosis of diverse pulmonary diseases, usually including pleural effusion and pneumothorax. However, the use of chest ultrasound may be also critical in the evaluation of chest wall diseases. Therefore, we present an interesting case of a patient with metastases of lung cancer to the rib, detected during the chest wall ultrasound examination. By representing a non-invasive, surface-imaging technique with several advantages, chest ultrasound may evolve to a valid, bed-side diagnostic tool for the diagnosis and follow up of lung cancer with metastases in the chest wall...

Point-of-care ultrasonography has become widely used in diagnosis and managements of patients. In the field of anesthesiology, ultrasound guided nerve blocks and central venous catheterization (CVC), and transesophageal echocardiography (TEE) have become popular. Now, ultrasound devices are familiar to anesthesiologists. In pre-anesthetic patient risk evaluation, the sonographic results of transthoracic echocardiography (TTE) or the examination of deep venous thrombus are often helpful for anesthesia planning...

Patients with cardiac disease have high mortality rates, mainly owing to shock. Therefore, evaluation of cardiac function is one of the most challenging issues in the intensive and critical care unit. Cardiac point-of-care tests using ultrasound, such as focus assessed transthoracic echo (FATE) and rapid ultrasound in shock (RUSH). are useful for diagnosis and initial care of such patients. The author will introduce first a basic FATE protocol of how to scan from position 1-4, including subcostal 4-chamber, apical 4-chamber, parasternal long and short axis, and pleural scanning...

The left internal thoracic artery (ITA) is currently an artery of choice for revascularization of coronary arteries. Ultrasonographic duplex scanning (USDS) and ultrasound Doppler flowmetry (UDF) are sequential techniques to control patency of the ITA at stages of rendering care for patients on restoring coronary blood flow. We compared two methods of measuring the volumetric blood flow velocity: by means of USDS and UDF. The obtained results were statistically processed. It was determined that transthoracic USDS and intraoperative UDF in the assessment of the volumetric blood velocity through the ITA in patients with coronary artery disease are comparable methods, provided the patients have similar parameters of central haemodynamics...

Transmit beamforming has a strong impact on several factors that govern image quality, field-of-view, and frame-rate in ultrasound imaging. For cardiac applications, the visualization of fine structures and the ability to track their motion is equally important. Consequently, beamforming choices for echocardiography aim to optimize these trade-offs. Acoustic clutter can dramatically impact image quality and degrade the diagnostic value of cardiac ultrasound imaging. Clutter levels, however, are closely tied to the choice of beamforming configuration...

The use of transthoracic ultrasound has acquired a wide consensus among respiratory physicians during the last few years. The developing of portable and easily available devices favorites patient's bedside evaluation. Transthoracic ultrasound provides rapid, real-time and low-cost diagnostic information, allowing image-guided chest interventions and reducing procedural risks. The different acoustic impedance between aerated and not aerated organs produces artifacts known as A lines, B lines, sliding sign, lung point, etc...

OBJECTIVE: Transthoracic echocardiography (TTE) is important in the management of critically ill patients, yet it has not been incorporated into many residency programs' curricula. Our objective is to determine if trainees undergoing a 60-minute training session on TTE have improved knowledge, ultrasound skills, and increases the utilization of TTE during their rotation in the intensive care unit (ICU). We will also compare the results of participants with prior TTE exposure to TTE-naïve trainees...

The study aimed to evaluate the effect of pregnancy on heart diameters and function in goats. Transthoracic echocardiography of 12 female dairy goats of two Polish regional breeds was performed. A Mindray M7 diagnostic ultrasound system with Phased Array transducer was used. Simultaneously, electrocardiography was recorded. All animals were examined four times - at mating season, at the end of the first trimester, at the end of the second trimester and just before kidding. Eleven measurements were taken each time: aortic and left atrial diameter (AoD and LAD), right and left ventricular internal diameter in diastole (RVIDd and LVIDd), left ventricular internal diameter in systole (LVIDs), inter-ventricular septum thickness in diastole and systole (IVSd and IVSd) and left ventricular posterior wall in diastole and systole (LVPWd and LVPWs), maximum left and right ventricular outflow tract velocity (RVOT Vmax and LVOT Vmax)...

Ultrasound-guided transthoracic needle biopsy (USgTTNB) can only be used for peripheral tumours that contact the pleura. Sonographic accessibility of the entire lung can be achieved using one-lung flooding. In this study, feasibility, sensitivity and complication rate of USgTTNB of lung nodules after one-lung flooding in an ex vivo and in vivo lung tumour model were assessed. USgTTNB was performed ex vivo after one-lung flooding in 10 resected human lung lobes containing carcinoma or metastasis. USgTTNB after one-lung flooding and simulation of a lung nodule was conducted in vivo in 5 animals...

BACKGROUND: Prior studies have shown that both heart failure (HF) and atrial fibrillation (AF) are factors that impact left atrial function and structure. However, right atrial (RA) function measured as RA emptying fraction (RAEF) on echocardiography has not been analyzed systematically in a chronic HF population. The aim of this study was to assess RA volume index (RAVI) and RAEF in patients with chronic HF and patients with hypertension (HTN) and to relate these findings to other cardiopulmonary ultrasound parameters and 12-month outcomes...
