Echocardiography

In adults being evaluated for cardiac function by echocardiography, an initial assessment of left ventricular ejection fraction by artificial intelligence was superior to an assessment by a sonographer, researchers reported.

A recent study found that video-based motion analysis from a smartphone correctly detected carotid artery stenosis in adults.

Dyad Medical announced its application providing data-driven analysis of echocardiogram images has received 510(k) clearance from the FDA.

The combination of echocardiography, N-terminal pro-B-type natriuretic peptide and pulmonary artery to ascending aorta diameter ratio predicted severe pulmonary hypertension in patients with COPD with high sensitivity and specificity.

Patients with autosomal dominant polycystic kidney disease have a preferable cardiac profile before transplantation and better survival and major adverse cardiovascular event-free survival rates vs. patients with other kidney diseases.

Mitral annulus calcification may be an independent risk factor for all-cause mortality and was more common among older patients and those with concomitant mitral valve dysfunction, according to data published in Mayo Clinic Proceedings.

Valve-in-valve transcatheter aortic valve replacement with a self-expanding vs. balloon-expandable valve was associated with improved valve hemodynamics and no between-group differences in clinical outcomes, researchers reported at EuroPCR.

Individuals with mildly elevated estimated right ventricular systolic pressure had a high burden of mortality and consequential premature deaths, researchers reported in the European Respiratory Journal.

Patients who were hospitalized with COVID-19 may have developed cardiac complications as they continued presenting with dyspnea 1 year after hospital discharge, according to a small study presented at EuroEcho 2021.

Compared with other models, N-terminal pro-brain natriuretic peptide is a low burden approach that gives the most “moderate discrimination” while predicting heart failure in patients with chronic kidney disease, data at ASN Kidney Week show.
