Article
Common genetic variants and modifiable risk factors underpin hypertrophic cardiomyopathy susceptibility and expressivity
Hypertrophic cardiomyopathy (HCM) is a common, serious, genetic heart disorder. Rare pathogenic variants in sarcomere genes cause HCM, but with unexplained phenotypic heterogeneity. Moreover, most patients do ...

Automatic Scar Segmentation from DE-MRI Using 2D Dilated UNet with Rotation-Based Augmentation
Delayed enhancement (DE) MRI is an important tool in diagnosis of cardiovascular disease as it can reveal different characteristics of the myocardium scars including infarction and no-reflow. Automatic segment...

Chapter
Acute Myocardial Infarction and Postinfarction Remodeling
Cardiac magnetic resonance (CMR) is ideally suited to evaluate the consequences of myocardial ischemia and infarction (MI) because of its excellent spatial resolution and ability to characterize tissue. Cine C...

Open AccessCorrection to: Simple motion correction strategy reduces respiratory-induced motion artifacts for k-t accelerated and compressed-sensing cardiovascular magnetic resonance perfusion imaging
Figure 1 of this original publication contained a minor error as one of the lines in the “Reconstruction pipline” was not visible. The updated Fig. 1 is published in this correction article.

Open AccessCardiovascular magnetic resonance detects the progression of impaired myocardial perfusion reserve and increased left-ventricular mass in mice fed a high-fat diet
Impaired myocardial perfusion reserve (MPR) is prevalent in obesity and diabetes, even in the absence of obstructive coronary artery disease (CAD), and is prognostic of adverse events. We sought to establish t...
