Application Value of Myocardial Segmental Thickness Variability Measured by Echocardiography in Distinguishing Ischemic and Nonischemic Dilated Cardiomyopathy.
J Clin Ultrasound
January 2025
Department of Cardiac Surgery, Nanjing Drum Tower Hospital, The Affiliated Hospital of Nanjing University Medical School, Nanjing, China.
Purpose: The aim of this study is to evaluate the clinical value of myocardial segmental thickness variability (STV) measured by echocardiography in distinguishing ischemic cardiomyopathy (ICM) from nonischemic dilated cardiomyopathy (NIDCM).
Methods: This study included 120 patients diagnosed with dilated cardiomyopathy, divided into ICM (n = 43) and NIDCM (n = 77) groups based on coronary angiography. Traditional echocardiographic parameters, STV, and regional wall motion abnormalities (RWMA) were compared.

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.

Department of Cardiology and Vascular Medicine, West German Heart and Vascular Center, University Hospital Essen, Germany.
Background And Aims: Cardiotoxicity from immune checkpoint inhibitor (ICI) therapy is a challenge in clinical practice, and the assessment of ICI-related myocarditis (ICI-M) is often complicated by a variable phenotype. Cardiac magnetic resonance imaging (CMR) is used frequently, but evidence is poor. Here, we aim to assess the role of CMR in the assessment of suspected ICI-M in a real-world clinical setting.

Swine are increasingly utilized in cardiovascular research due to their anatomical and physiological similarities to humans, particularly for studying diastolic dysfunction. While MRI offers excellent structural imaging, echocardiography provides superior real-time assessment of diastolic parameters. To address the lack of standardized methods and reduce variability across studies, we present a comprehensive guide for performing echocardiography in Yorkshire pigs, detailing anatomical considerations, equipment requirements, and technical approaches.

Background: Since the transcatheter valve-in-valve (ViV) procedure was introduced in 2007, a few cases of infective endocarditis (IE) following the ViV procedure have been reported, which can be predisposed by older age, pre-existing medical conditions, and procedural techniques. Paravalvular abscesses constitute a rare complication of IE, resulting from extending IE beyond the valve annulus, less commonly caused by species. This complication is more common in prosthetic valves, particularly bioprosthetic valves.
