Left Atrial Remodeling and Function in Various Left Ventricular Hypertrophic Phenotypes.
Eur Heart J Cardiovasc Imaging
January 2025
Heart Institute. Department of Cardiology. Cardiovascular Imaging Unit. Hospital Universitari Germans Trias i Pujol, Barcelona, Spain.
Aims: How the underlying etiology and pathophysiology of left ventricular (LV) hypertrophy affects LA remodeling and function remains unexplored. The present study aims to investigate the influence of various hypertrophic phenotypes on LA remodeling and function.
Methods And Results: Patients with LV hypertrophy who underwent cardiac magnetic resonance (CMR) were compared to a control group.
A Novel Staging System of Cardiac Damage in Aortic Stenosis based on Multi-Chamber Myocardial Deformation.
Eur Heart J Cardiovasc Imaging
January 2025
Department of Cardiology, Istituto Auxologico Italiano, IRCCS, Milan, Italy.
Aims: This study evaluates whether multi-chamber myocardial deformation analysis using speckle tracking echocardiography (STE) can enhance validated current staging systems and improve risk stratification for patients with moderate-to-severe aortic stenosis (AS).
Methods And Results: We reanalyzed 2D, Doppler, and STE data obtained from two cohorts: derivation (654 patients, median age: 82 years; 51% men) and validation (237 patients, median age: 77 years; 55% men) with at least moderate AS (aortic valve area<1.5 cm2).
Left atrial appendage velocity, association with inflammatory indices in non-valvular atrial fibrillation patients.
Future Cardiol
January 2025
Echocardiography research Center, Rajaie cardiovascular medical and research Center, Iran University of Medical Science, Tehran, Iran.
Introduction: Decreased left atrial appendage emptying velocity (LAAV) is a marker for thrombus formation. This study evaluates the association between LAAV and inflammatory indices in non-valvular atrial fibrillation (AF) patients.
Methods: The study population was 1428 patients with AF, 875 of whom enrolled.
Cardiac computer tomography-derived radiomics in assessing myocardial characteristics at the connection between the left atrial appendage and the left atrium in atrial fibrillation patients.
Front Cardiovasc Med
January 2025
Department of Medical Imaging, The Second Hospital of Hebei Medical University, Shijiazhuang, China.
Objectives: To evaluate the feasibility of utilizing cardiac computer tomography (CT) images for extracting the radiomic features of the myocardium at the junction between the left atrial appendage (LAA) and the left atrium (LA) in patients with atrial fibrillation (AF) and to evaluate its asscociation with the risk of AF.
Methods: A retrospective analysis was conducted on 82 cases of AF and 56 cases in the control group who underwent cardiac CT at our hospital from May 2022 to May 2023, with recorded clinical information. The morphological parameters of the LAA were measured.
Caval vein obstruction resulting in right to left shunt and desaturation post-endocardial pacing implantation in a 3-year old: a case report.
Eur Heart J Case Rep
January 2025
Echocardiography Department, Great Ormond Street Hospital for Children, Great Ormond Street, London WC1N 3JH, UK.
Background: Superior caval vein obstruction is a rare complication of endocardial pacing lead implantation that can result in a right to left shunt.
Case Summary: A 3-year-old child with type 2 Brugada syndrome presented with mild cyanosis post-endocardial pacing implantation due to evolutionary right superior caval vein obstruction. This obstruction resulted in a right to left shunt across a previously unrecognized patent levo-atrial cardinal vein associated with partial anomalous pulmonary venous drainage.
