Cine-CMR in our patient revealed thinned, dyskinetic basal inferior wall aneurysm and DE-CMR confirmed the presence of thrombi. CMR proved to be a comprehensive diagnostic tool in identifying myocardial viability/candidacy for surgical revascularization, confirming severity of mitral regurgitation, and detecting ventricular aneurysm and mural ...

The incidence of LVT after STEMI is not negligible and was accurately detected by CMR. Localization of myocardial infarction, time to reperfusion, ejection fraction and left ventricle end systolic volume are the most important predictors of left ventricle thrombus formation.

CMR criteria for diagnosing LV thrombus were characterized as a non-enhancing mass within the LV cavity with distinct margins from the ventricular endocardium and distinguished from papillary muscles, chordae tendinae, trabeculations, or artifact. LV thrombus was evaluated on a thorough evaluation of both short- and long-axis views.

2025年2月14日 · LVT was identified during hospitalization through cardiac magnetic resonance imaging (CMR) or transthoracic echocardiography (TTE). Major adverse cardiac and cerebrovascular events (MACCEs) were recorded over 36 months follow-up. The predictive value of AMR was evaluated by logistic regression and receiver operating characteristic (ROC) analysis.

CMR = cardiac magnetic resonance; d = days; LVT = left ventricular thrombus; MI = myocardial infarction. The present work demonstrates a significant impact of the delay between STEMI and CMR on the detection of LVT, suggesting that CMR performed within the first 5 days might leave many LVT undetected.

We hypothesis that tissue characteristics and strain parameters by cardiac magnetic resonance (CMR) imaging may indicate the interactions of LVT with ventricular myocardium remodeling at both acute stage and chronic stages in STEMI patients.

2015年6月22日 · We identified body mass index (odds ratio 1.18; p = 0.01), baseline platelet count (odds ratio 1.01, p = 0.01) and infarct size as assessed by use of CMR (odds ratio 1.03, p = 0.02) as best predictors for LVT. The agreement between TTE and CMR for the detection of LVT is substantial (kappa = 0.70).

Using trans-thoracic echocardiography (TTE), the prevalence of LVT in chronic heart failure is reported to be 20–40%. More recently contrast enhanced cardiac magnetic resonance imaging (CE-CMR) has emerged as an important non-invasive tool for the assessment of heart failure and has the capability to diagnose LVT with greater ease than TTE.

2024年6月17日 · CMR tissue tracking is a noninvasive quantitative measurement of ventricular strain using myocardial deformation for left ventricular (LV) global or segmental function analysis. It combines myocardial function with pathological characteristics to detect subtle changes in cardiac function and accurately evaluate left ventricular wall motion [7, 8].

2021年6月1日 · Left ventricular thrombus (LVT) is a frequent complication after an acute myocardial infarction (MI) and is associated with systemic thromboembolism. Cardiovascular magnetic resonance imaging (CMR) is the diagnostic gold-standard, but its limited availability makes screening tools necessary.
