The complex morphological structure of the left ventricular endocardial surface and its relation to the severity of arterial stenosis has not yet been thoroughly investigated due to the limitations of conventional imaging techniques. By exploiting the recent developments in Multirow-Detector Computed Tomography (MDCT) scanner technology, the complex endocardial surface morphology of the left ve...
OBJECTIVES Recently published clinical guidelines recommend cardiac resynchronisation therapy (CRT) for patients with heart failure (HF) with reduced LVEF and non-left bundle branch block (non-LBBB) QRS morphology. We sought to define the potential benefit of CRT in these patients through meta-analysis of randomised controlled trials (RCTs) that have reported outcomes in patients with non-LBBB ...
Introduction Cardiac MRI (CMR) is used to follow patients after TOF repair to assess pulmonary regurgitation (PR), pulmonary stenosis (PS) and right ventricular (RV) function. 4D flow-sensitive MRI techniques enable visualization of complex flow patterns [1],[2]. With the ability to simultaneously acquire morphology and hemodynamics for visualization and quantification, they may improve evaluat...
A 62-year-old man admitted for presyncope presented two symptomatic sustained ventricular tachycardia with right bundle branch morphology and inferior axis suggesting a pathology of the left ventricular lateral wall, the site where Cardiac Magnetic Resonance demonstrated a thinned, hypokinetic segment with fibro-fatty subepicardial infiltration. A very localized Left Dominant Arrhythmogenic Car...
Background Athletes demonstrate major adaptative changes in their hearts with high level of exercise. However the long term consequences of endurance training were not completely understood. We aimed to to explore the effect of long term endurance exercise on cardiac morphology and function, and diffuse fibrosis, and assess the significance of any discovered changes (correlation with documented...
Cardiovascular MR (CMR) has an emerging role in the noninvasive diagnostic assessment of heart failure (HF). Different imaging sequences allow for a detailed assessment of cardiac morphology, function, myocardial perfusion, tissue characterization, and blood flow measurement. This article reviews the key applications of CMR in HF, with special focus on how CMR may influence the diagnostic and t...
