BACKGROUND: Although cuff blood pressure measurement is a critical parameter to calculate myocardial work (MW) noninvasively, there is no recommendation about when and how to measure it. Accordingly, we sought to evaluate the effects of the timing during the echo study and the patient's position on the scanning bed during the cuff blood pressure measurement on MW parameter calculations. METHODS: 101 consecutive patients (44 women, 66±14 years) undergoing clinically indicated echocardiography were prospectively enrolled...

PURPOSE OF REVIEW: This review aims to provide a concise overview of key recommendations, with a specific focus on common challenges faced by intraoperative echocardiographers when dealing with frequently encountered valvular pathologies and mechanical circulatory support. It offers valuable insights for medical practitioners in this field. RECENT FINDINGS: The American Society of Echocardiography (ASE) and the American College of Cardiology/American Heart Association (ACC/AHA) have released updated comprehensive guidelines for the use of transesophageal echocardiography (TEE) for the assessment of cardiac structures and implanted devices to help guide intraoperative decision-making...

BACKGROUND: Although regional wall motion abnormality (RWMA) detection is foundational to transthoracic echocardiography (TTE), current methods are prone to inter-observer variability. We aimed to develop a deep learning (DL) model for RWMA assessment and compare it to expert and novice readers. METHODS: We used 15,746 TTE studies-including 25,529 apical videos-which were split into training, validation, and test datasets. A convolutional neural network was trained and validated using apical 2-, 3-, and 4-chamber videos to predict the presence of RWMA in 7 regions defined by coronary perfusion territories, using the ground truth derived from clinical TTE reports...

BACKGROUND: Echocardiographic grading of mitral regurgitation (MR) in mitral valve prolapse (MVP) is challenging. 3D vena contracta area (3D VCA) has been proposed as valuable method. However, data defining the cut-off values of severity and validation in the subset of patients with MVP are scarce. The aim of this study was to validate the 3D VCA by 3D transesophageal color-Doppler echocardiography (3D-TEE) in patients with MVP and to define the cut-off values of severity grading. The secondary aim was to compare 3D VCA to the EROA-PISA method...

INTRODUCTION: After ST-segment elevation myocardial infarction (STEMI), follow-up imaging is currently recommended only in patients with left ventricular ejection fraction (LVEF) <40%. LV global longitudinal strain (GLS) showed to improve risk stratification over LVEF in these patients, but has not been thoroughly studied during follow-up. Aim of this study was to explore the changes in LVGLS after STEMI and their potential prognostic value. MATERIALS AND METHODS: Data were analyzed from an ongoing STEMI registry...

BACKGROUND: Mitral annulus calcification (MAC) represents a degenerative process resulting in calcium deposition in the mitral valve apparatus. MAC is associated with adverse clinical outcomes. We sought to examine the long-term significance of mild MAC and its relationship to subsequent mitral valve dysfunction (MVD) and mortality in patients without MVD on the initial echocardiogram. METHODS: A total of 1420 patients with mild MAC and no MVD at baseline, and one or more follow-up echocardiograms at least one year after the baseline echocardiogram were included in the analysis...

INTRODUCTION: Left ventricular trabeculations (LVTs) are common findings in athletes. Limited information exists regarding clinical significance, management, and outcome. OBJECTIVES: To study the prevalence and morphologic characteristics of LVTs in elite athletes, with a focus on clinical correlates and prognostic significance. METHODS: We enrolled 1.492 Olympic elite athletes of different sports disciplines with ECG, echocardiogram, and exercise stress test...

Interventional echocardiography is a rapidly growing field with the disciplines of cardiology and anesthesiology, with the rise of advanced transcatheter procedures making skilled imagers more important than ever. However, these procedures also involve frequent manipulation of the transesophageal echocardiography (TEE) probe, which means interventional echocardiographers (IE) are at risk of long-term occupational radiation exposure. Studies have shown that radiation exposure is linked to various health issues, including cancer, cataracts, hypertension, hyperlipidemia, endothelial dysfunction, vascular aging, and early atherosclerosis...

Accurate knowledge of right ventricle (RV) volumes and ejection fraction is fundamental to providing optimal care for pediatric patients with congenital and acquired heart disease, as well as pulmonary hypertension. Traditionally, these volumes have been measured by cardiac magnetic resonance (CMR) because of its accuracy, reproducibility, and freedom from geometric assumptions. More recently, an increasing number of studies have described the measurement of RV volumes by three-dimensional echocardiography (3DE)...
