Machine learning techniques designed to recognize views and perform measurements are increasingly used to address the need for automation of the interpretation of echocardiographic images. The current study was designed to determine whether a recently developed and validated deep learning (DL) algorithm for automated measurements of echocardiographic parameters of left heart chamber size and function can improve the reproducibility and shorten the analysis time, compared to the conventional methodology. The DL algorithm trained to identify standard views and provide automated measurements of 20 standard parameters, was applied to images obtained in 12 randomly selected echocardiographic studies.

As differences in normal values might impact clinical decision-making, we aimed to establish sex-, age- and race-specific normative values for AVA and Doppler parameters using data from the World Alliance Societies of Echocardiography (WASE) Study.
Methods And Results: Two-dimensional transthoracic echocardiographic studies were obtained from 1903 healthy adult subjects (48% women).
Article Synopsis
- - The study evaluates left atrial (LA) size and function using 2D and 3D echocardiography in 1,765 healthy individuals, analyzing the effects of age, sex, and race on LA parameters.
- - Findings indicate that while LA volumes are similar for men and women, women have better passive emptying fractions, and LA size and function change with age, particularly showing variations in functional indices.
- - The research suggests that normal LA volume values can apply to both sexes, but significant differences arise due to aging, with noted variations in LA volumes among different racial groups.
Annuloplasty is the cornerstone of surgical mitral valve repair. A percutaneous transvenous catheter-based approach for mitral valve repair was tested by placing a novel annuloplasty device in the coronary sinus of sheep with acute ischemic mitral regurgitation. Mitral regurgitation was reduced from 3-4+ to 0-1+ in all animals (P < 0.
