Automated 4D flow cardiac MRI pipeline to derive peak mitral inflow diastolic velocities using short-axis cine stack: two centre validation study against echocardiographic pulse-wave doppler

BMC Cardiovascular Disorders, 2023
Background Measurement of peak velocities is important in the evaluation of heart failure. This study compared the performance of automated 4D flow cardiac MRI (CMR) with traditional transthoracic Doppler echocardiography (TTE) for the measurement of ...

Chronic high‐fat diet induces multi‐organ dysfunction and metabolic homeostasis disruption in Macaca fascicularis

Animal Models and Experimental Medicine, EarlyView.
An 18‐month HFD successfully established a translational Macaca fascicularis model replicating key metabolic disorders (MASH, diabetes, cardiac hypertrophy). MASH was determined by liver biopsy histology, the presence steatosis, inflammatory infiltration, hepatocytic ballooning, and fibrosis were considered as MASH; diabetes was diagnosed according to ...

A Wireless, Wearable Carotid Doppler Ultrasound Aids Diagnosis and Monitoring of Pericardial Tamponade: A Case Report

Critical Care Explorations, 2023
BACKGROUND:. Pericardial tamponade can often be diagnosed through clinical findings and echocardiography; however, the diagnosis can be aided by demonstrating the hemodynamic consequences of the effusion. We describe the use of a wearable carotid Doppler

Doppler Echocardiography [PDF]

Circulation, 1973
A range-gated pulsed Doppler flowmeter has recently been developed that measures the average velocity of blood flow within a small tear-drop shaped (4 mm by 2 mm) sample volume. Unlike the continuous wave Doppler, the distance from the transducer face to the sampling site can be continuously varied by a range adjustment knob.

Adipocytes in Aortic Stenosis: Association With Clinical and Morphological Indices

Clinical Anatomy, EarlyView.
ABSTRACT Recently, great attention has been given to understanding the new pathogenetic mechanisms underlying aortic stenosis (AS). The study aims to understand the role of mature adipocytes in AS and their association with histologic, clinical, and echocardiographic data, an area previously overlooked in AS research.

Two-dimensional and Doppler echocardiographic findings of congenital coronary artery fistula

The Turkish Journal of Pediatrics, 1992
Three patients with coronary artery fistula confirmed by coronary angiography and surgery were studied using two-dimensional and Doppler echocardiography. Two of these patients had left coronary artery-right ventricle fistula.

Endovascular Stenting for Pulmonary Vein Stenosis Following Atrial Fibrillation Ablation: From Diagnosis to Intervention

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Pulmonary vein stenosis (PVS) is an uncommon but serious complication of atrial fibrillation (AF) ablation, often misinterpreted as primary pulmonary disease. Timely identification is essential to prevent irreversible injury and to guide appropriate referral for interventional management. Case Presentations Through the discussion of

Cardiac imaging in athlete’s heart: current status and future prospects

Cardiovascular Ultrasound, 2023
Background Physical activity contributes to changes in cardiac morphology, which are known as “athlete’s heart”. Therefore, these modifications can be characterized using different imaging modalities such as echocardiography, including Doppler (flow ...
