Clinical treatment of cardiac arrhythmia by radiofrequency ablation (RFA) currently lacks quantitative and precise visualization lesion formation in the myocardium during procedure. This study aims at evaluating thermal dose (TD) imaging obtained from real-time magnetic resonance (MR) thermometry on heart as a relevant indicator extent. MR temperature mapping based Proton Resonance Frequency Shift (PRFS) method was performed 1.5 T heart, with 4 to 5 slices acquired per heartbeat. Respiratory...
Purpose The therapy endpoint most commonly used in MR‐guided high intensity focused ultrasound is the thermal dose. Although namely correlated with nonviable tissue, it does not account for changes mechanical properties of tissue during ablation. This study presents a new acquisition sequence multislice, subsecond and simultaneous imaging temperature displacement Methods A single‐shot echo planar was implemented using pair motion‐encoding gradients, alternated polarities. first pulse...
A new real-time MR-thermometry pipeline was developed to measure multiple temperature images per heartbeat with 1.6×1.6×3 mm3 spatial resolution. The method evaluated on 10 healthy volunteers and during radiofrequency ablation (RFA) in sheep.Multislice, electrocardiogram-triggered, echo-planar imaging combined parallel imaging, under free breathing conditions. In-plane respiratory motion corrected magnitude by an optical flow algorithm. Motion-related susceptibility artifacts were...
Cardiovascular magnetic resonance T1ρ mapping may detect myocardial injuries without exogenous contrast agent. However, multiple co-registered acquisitions are required, and the lack of robust motion correction limits its clinical translation. We introduce a single breath-hold method that includes model-based non-rigid correction. A single-shot electrocardiogram (ECG)-triggered balanced steady state free precession (bSSFP) 2D adiabatic sequence collects five T1ρ-weighted (T1ρw) images with...
To determine whether fully automated artificial intelligence-based global circumferential strain (GCS) assessed during vasodilator stress cardiovascular (CV) magnetic resonance (CMR) can provide incremental prognostic value.Between 2016 and 2018, a longitudinal study included all consecutive patients with abnormal CMR defined by the presence of inducible ischaemia and/or late gadolinium enhancement. Control subjects normal were selected using propensity score-matching. Stress-GCS was...
A cardiac MRI model incorporating the ischemic late gadolinium enhancement (LGE) parameters of extent, transmurality, location, and midwall LGE significantly outperformed traditional risk factors in predicting all-cause mortality participants with cardiomyopathy.
Background Multimodality imaging is essential for personalized prognostic stratification in suspected coronary artery disease (CAD). Machine learning (ML) methods can help address this complexity by incorporating a broader spectrum of variables. Purpose To investigate the performance an ML model that uses both stress cardiac MRI and CT angiography (CCTA) data to predict major adverse cardiovascular events (MACE) patients with newly diagnosed CAD. Materials Methods This retrospective study...
Abstract Background Late gadolinium enhancement (LGE) extent is the basis for risk stratification of hypertrophic cardiomyopathy (HCM) using cardiac magnetic resonance (CMR). LGE has been recently added in guidelines by European Society Cardiology (ESC) and American College (ACC), setting a threshold at ≥15% left ventricular mass. However, SCD become an uncommon event this population, mortality now mostly related to other phenotypes, such as stroke heart failure. While previous studies have...
Abstract Introduction The presence and extent of late gadolinium enhancement (LGE) assessed by cardiac magnetic resonance imaging (CMR) are strong prognosticators death in patients with non-ischaemic dilated cardiomyopathy (DCM), defined as left ventricular (LV) dilation ejection fraction (LVEF)<50%. Although the current guidelines concept "isolated LV dilation" (ILVD) preserved LVEF≥ 50%, prognostic value "LGE granularity" is not established this population. Purpose To assess...
Abstract Background Cardiac sarcoidosis (CS) is an underdiagnosed condition characterized by the formation of non-caseating granuloma in myocardium, potentially leading to arrhythmia, acute heart failure and sudden cardiac death. Early screening for diagnosis crucial optimize treatment delay progression. Hemodynamic forces (HDFs) are a measurement global force exchanged between blood volume myocardium assessed during magnetic resonance imaging (CMR), novel noninvasive parameter used detect...
Abstract Background After the REVIVED trial, utility of cardiovascular magnetic resonance (CMR) assessing myocardial viability to guide coronary revascularisation remains controversial. Objective To assess prognostic impact guided by CMR-based predict death in patients with ischaemic cardiomyopathy (ICM) and reduced left ventricular ejection fraction (LVEF) <50%. Methods From 2008 2022, we included all consecutive ICM referred for assessment a multicentric study. Eligible had ≥70%...
Abstract Background Systemic sclerosis (SSc) is a connective tissue disease characterized by sustained inflammation, microvascular pathology changes and fibrosis. Cardiac comorbidities, particularly pulmonary arterial hypertension (PAH), are the leading cause of mortality among SSc patients. Early PAH diagnosis remains difficult. Cardiovascular magnetic resonance imaging (CMR) has emerged as great noninvasive tool to assess cardiological impact in SSc. Hemodynamic forces (HDF) measurement...
Abstract Background Although the presence and extent of ischaemic late gadolinium enhancement (LGE) as assessed by cardiovascular magnetic resonance (CMR) have emerged robust predictors outcomes in patients with cardiomyopathy (ICM), prognostic significance non-ischaemic LGE is not well established. Objective To assess impact a large cohort ICM reduced left ventricular ejection fraction (LVEF) undergoing CMR for myocardial viability. Methods Between 2008 2022, all consecutive referred...
Abstract Background Although the presence and extent of ischaemic late gadolinium enhancement (LGE) assessed by cardiovascular magnetic resonance (CMR) are robust predictors outcomes in patients with cardiomyopathy (ICM), prognostic significance other ischaemic-LGE parameters is not well established, no integrated score exists. Purpose This study aims to evaluate additional value a model that assesses granularity over traditional factors predicting mortality ICM patients. The includes...
