Hemodynamic analysis of left ventricular unloading with Impella versus IABP during VA-ECMO.
Acta Bioeng Biomech
June 2024
1Department of Biomedical Engineering, Hefei University of Technology, Hefei, People's Republic of China.
: The utilization of intra-aortic balloon pump (IABP) and Impella has been suggested as means of left ventricular unloading in veno-arterial extracorporeal membrane oxygenation (VA-ECMO) patients. This study aimed to assess the local hemodynamic alterations in VA-ECMO patients through simulation analyses. : In this study, a 0D-3D multiscale model was developed, wherein resistance conditions were employed to define the flow-pressure relationship.

Department of Cardiothoracic and Vascular Surgery, Deutsches Herzzentrum der Charité (DHZC), Berlin, Germany. DZHK (German Centre for Cardiovascular Research), Partner Site Berlin, Berlin, Germany.
Objectives: This fourth report aimed to provide insights into patient characteristics, outcomes, and standardized outcome ratios of patients implanted with durable Mechanical Circulatory Support across participating centers in the European Registry for Patients with Mechanical Circulatory Support (EUROMACS) registry.
Methods: All registered patients receiving durable mechanical circulatory support up to August 2024 were included. Expected number of events were predicted using penalized logistic regression.
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).
Minimally Invasive Puncture and Drainage Surgery for the Treatment of Thalamic Hemorrhage Guided by a 3D-printed Guide Plate.
J Craniofac Surg
January 2025
School of Medical Imaging, Hangzhou Medical College, Hangzhou, China.
Thalamic hemorrhage is a type of intracerebral hemorrhage with high disability and mortality rates. Because of its deep bleeding location, irregular shape of the hematoma, and compression of the third ventricle, it is not suitable for craniotomy. This paper reports a case of a 63-year-old male patient who sought medical attention for left-sided basal ganglia and thalamus hemorrhage that broke into the ventricles.
