In order to determine acute cardiac involvement in patients with COVID-19, we quantitatively evaluated tissue characteristics and mechanics by non-invasive magnetic resonance (CMR) a cohort of within the first 10 days onset COVID symptoms.Twenty-five reverse transcription polymerase chain reaction confirmed COVID-19 at least one marker [cardiac symptoms, abnormal electrocardiograph (ECG), or biomarkers] 25 healthy age- gender-matched control subjects were recruited study. Patients divided...
The prognostic value of left ventricular segmental strain (SS) in ST-elevation myocardial infarction (STEMI) remains unclear.
The prognostic value of left ventricular (LV) myocardial trabecular complexity on cardiovascular magnetic resonance (CMR) in dilated cardiomyopathy (DCM) remains unknown. This study aimed to evaluate the LV using fractal analysis patients with DCM. Consecutive DCM who underwent CMR between March 2017 and November 2021 at two hospitals were prospectively enrolled. primary endpoints defined as combination all-cause death heart failure hospitalization. events cardiac alone secondary...
BACKGROUND: Late gadolinium enhancement (LGE) cardiac magnetic resonance (CMR) is a standard technique for diagnosing myocardial infarction (MI), which, however, poses risks due to contrast usage. Techniques enabling MI assessment based on contrast-free CMR are desirable overcome the limitations associated with enhancement. METHODS: We introduce novel deep generative learning method, termed cine-generated (CGE), which transforms cine into LGE-equivalent images assessment. CGE features...
Objective: In this paper, we propose a fully automatic framework for myocardium segmentation of delayed-enhancement (DE) MRI images without relying on prior patient-specific information. Methods: We employ multicomponent Gaussian mixture model to deal with the intensity heterogeneity caused by infarcts. To differentiate from other tissues similar intensities, while at same time maintain spatial continuity, introduce coupled level set (CLS) regularize posterior probability. The CLS, as...
Background Arrhythmogenic cardiomyopathy (ACM) is characterized by progressive myocardial fibro‐fatty infiltration accompanied trabecular disarray. Traditionally, two‐dimensional (2D) instead of 3D fractal dimension (FD) analysis has been used to evaluate However, the prognostic value disorder assessed FD measurement remains unclear. Purpose To investigate right ventricular complexity in ACM patients using based on cardiac MR cine images. Study Type Retrospective. Population 85 (mean age: 45...
In arrhythmogenic cardiomyopathy (ACM), left ventricle-dominant presentation has poorer outcomes than right-dominant presentation, suggesting that interventricular functional disparity might play a role in patients' prognosis. However, the prognostic impact of ventricular discordance ACM patients remains unknown.
Increased pericardial adipose tissue (PEAT) is associated with a series of cardiovascular diseases (CVDs) and metabolic syndromes. Quantitative analysis PEAT by means image segmentation great significance. Although magnetic resonance (CMR) has been utilized as routine method for non-invasive non-radioactive CVD diagnosis, in CMR images challenging laborious. In practice, no public datasets are available validating automatic segmentation. Therefore, we first release benchmark dataset, MRPEAT,...

Abstract Aims The prognostic implication of left ventricular (LV) torsion on ST-elevation myocardial infarction (STEMI) is unclear. Methods and results We analysed cardiovascular magnetic resonance (CMR) findings 420 patients from a registry study (NCT03768453). These received CMR examination within 1 week after timely primary percutaneous coronary intervention. LV other indexes were measured. Compared with healthy control subjects, STEMI significantly decreased patients’ (1.04 vs. 1.63°/cm,...

Abstract Objectives Arrhythmogenic right ventricular cardiomyopathy (ARVC) is an inherited characterized by progressive fibrofatty infiltration of atrial and myocardium resulting in adverse cardiac events. Atrial function has been increasingly recognized as prognostically important for cardiovascular disease. As the (RA) strain a sensitive parameter to describe RA function, we aimed analyze prognostic value ARVC. Methods parameters were derived from magnetic resonance (CMR) images 105...
