Although 2D speckle-tracking echocardiography (STE) is important for the clinical quantification of myocardial function it remains unknown whether increased frame rates during exercise STE augment tracking success and absolute deformation values. 19 participants (15 male and 4 female; age 26.7±4.

Echocardiography is a well-established tool for evaluating bioprosthetic valve performance after transcatheter aortic valve replacement. The presence of higher-than-expected echocardiographic gradients is not an uncommon finding and can be related to different clinical settings. This case series proposes a practical and multiparametric approach to interpreting high residual gradients after transcatheter aortic valve replacement.

Background: Clonal hematopoiesis of indeterminate potential (CHIP) has been linked to intensified systemic inflammation and represents a novel risk factor for atherosclerotic cardiovascular diseases, including aortic stenosis (AS).
Objectives: This study aimed to assess the clinical impact of CHIP in a cohort of severe AS patients undergoing transcatheter aortic valve implantation (TAVI).
Methods: We enrolled 110 severe AS patients in this retrospective study.
Deep Learning-Based Identification of Echocardiographic Abnormalities From Electrocardiograms.

Background: Heart failure should be diagnosed as early as possible. Although deep learning models can predict one or more echocardiographic findings from electrocardiograms (ECGs), such analyses are not comprehensive.
Objectives: This study aimed to develop a deep learning model for comprehensive prediction of echocardiographic findings from ECGs.
Subclinical patterns of cardiac involvement by transthoracic echocardiography in individuals with mild initial COVID-19.

The aim of this study was to evaluate the subclinical patterns and evolution of cardiac abnormalities via transthoracic echocardiography (TTE) in patients with mild initial COVID-19 illness. A total of 343 infected individuals (163 males; age 44 (interquartile range, IQR 35-52) years) years) underwent serial TTE assessments at a median of 109 (interquartile range (IQR), 77-177) and 327 (276-379) days after infection. Compared with those of non-COVID-19-infected controls (n = 94, male n = 49), baseline systolic (LVEF, TAPSE) and diastolic function (e', a', E/e') were significantly different in infected participants (p < 0.
