AI Article Synopsis
- Tissue Doppler imaging (TDI) patterns from the left atrial appendage (LAA) were assessed using transesophageal echocardiography, revealing characteristic triphasic or biphasic tissue velocities similar to LAA flow.
- TDI velocities showed a strong correlation with flow measurements and were effective in patients with atrial fibrillation.
- Patients who experienced an embolic cerebrovascular incident had higher TDI velocities from the LAA compared to those without events, suggesting that TDI may enhance assessment of LAA function for thromboembolism risk.
Article Abstract
Tissue Doppler imaging (TDI) patterns from the left atrial appendage (LAA) were evaluated by transesophageal echocardiography. Reproducible, characteristic triphasic or biphasic tissue velocities similar to Doppler flow of the LAA were obtained. Patient peak TDI velocities correlated well with flow and were measurable in atrial fibrillation. Patients with an embolic cerebrovascular accident and in sinus rhythm had higher tissue TDI velocities from the LAA compared with patients without an event, and the groups had similar flow velocities. Hence, Doppler tissue contraction dynamics determined by TDI may complement flow velocities in evaluating LAA function for risk assessment of thromboembolism.

Pathology and Laboratory Medicine, Saint Michael's Medical Center, Newark, USA.
Perivascular epithelioid cell tumors (PEComas) are a rare group of mesenchymal neoplasms composed of perivascular epithelioid cells. While commonly found in the kidney, uterus, and soft tissues, PEComas of the liver are exceedingly rare. We present a case of a PEComa incidentally discovered in a 73-year-old female patient undergoing evaluation for abdominal pain.

Arteriovenous malformations (AVMs) are rare congenital vascular malformations with associated morbidities. We describe a neonatal case of upper limb high-flow AVM presenting with upper limb soft tissue mass and postnatal high-output heart failure. Doppler study suggested high-flow AVM, and later magnetic resonance angiography of the right upper limb confirmed the diagnosis.

: Systemic sclerosis (SSc) causes myocardial and microvascular impairment, with subclinical dysfunction and eventually permanent cardio-vascular damage. The long-term influence of SSc therapies on subclinical cardiovascular dysfunction is insufficiently investigated. We aimed to assess 2D and 4D cardiac ultrasound parameters of heart function in patients with different forms of SSc versus controls and to determine the evolution of cardiac function and arterial stiffness parameters under therapy.

Contrast-enhanced ultrasound (CEUS) is a promising modality for differentiating benign and malignant lesions in various organs, including the testis. Testicular tumors, common in young men, are often treated with radical orchiectomy, which can have significant consequences. This study aimed to analyze CEUS parameters and their association with malignant testicular tumors.

Severe COVID-19 is associated with a generalized inflammatory response leading to peripheral and organ perfusion disorders. : This study aimed to evaluate the usefulness of peripheral and organ perfusion assessments in the prediction of prognosis and mortality in patients with severe COVID-19. : In the first 48 h of hospitalization, peripheral perfusion (saturation, Finger Infrared Thermography-FIT; Capillary Refill Time-CRT), and the color Doppler renal cortex perfusion (RCP) were estimated in a group of 102 severe COVID-19 patients.
