Age‐Dependent Correlation of Pulmonary Function Impairment and Aortic Arch Stiffness in Mice

Pediatric Discovery, EarlyView.
This study examined the relationship between aortic arch stiffness and lung function in aging mice. Multiple linear regression modeling showed moderate to strong correlations between the rise in aortic arch stiffness and changes in lung function as the mice progressively aged.

Assessment of Double Outlet Left Ventricle in Pediatrics Using Transthoracic Echocardiography and Computed Tomographic Angiography

Pediatric Discovery, EarlyView.
The clinical manifestation of DOLV was atypical. TTE has a relatively high diagnostic accuracy for DOLV in pediatric, which is very valuable for its early detection. ABSTRACT Double outlet left ventricle (DOLV) is a rare congenital cardiac anomaly in which both great arteries originate entirely or predominantly from the morphologic left ventricle.

Method of checking the function of implanted artificial valve by pulsed Doppler echocardiography – in vitro study

Archives of Acoustics, 2015
The usefulness of pulsed Doppler echocardiography for verifying the function of implanted Bjork-Shiley tilting disc valve prosthesis was checked experimentally in vitro. The valve was built into a physical model of central blood circulation.

Consideration on Estimating Mean Pulmonary Artery Pressure Using Early Diastolic Pulmonary Regurgitation Velocity

Sonography, EarlyView.
ABSTRACT Estimation of mean pulmonary artery pressure (mPAP) using peak velocity of pulmonary regurgitation (PR) obtained via continuous‐wave Doppler echocardiography has been applied in clinical practice. However, the theoretical basis for this method and whether to include right atrial pressure (RAP) in the calculation vary across reports, with no ...

Artificial Intelligence Guided Nonexpert Echocardiogram in the COVID‐19 Health Action Response in Marines 2.0 Study

Sonography, EarlyView.
ABSTRACT Purpose Echocardiography is a widely utilized cardiac imaging modality, but accessibility can be limited by cost and lack of skilled sonographers. We demonstrate the use of point‐of‐care ultrasound (POCUS) with an embedded deep learning algorithm to guide novice users in obtaining diagnostic‐quality echocardiographic images and ejection ...
