Cardiovascular Magnetic Resonance Guided Revascularisation
… patients is increasingly recognised. Established Cardiovascular Magnetic Resonance (CMR) techniques already provide much of the relevant functional information and the absence of ionising radiation makes CMR ideal for serial examinations. However, new CMR techniques continue to emerge, and require …

A subspace approach to accelerated cardiovascular magnetic resonance imaging
"Magnetic resonance imaging (MRI) is a uniquely flexible tool for imaging the heart, as it has the potential to perform a significant number of structural and functional cardiovascular assessments. However, the low imaging speed of MRI has limited its clinical application. The assessments that are …

Advanced Techniques for Cardiovascular Magnetic Resonance Imaging in Cases of Irregular Motion
Magnetic resonance imaging (MRI) has recently been shown to provide valuable information for image-guided ablation therapy used to treat patients suffering from cardiac arrhythmia. This requires isotropic high resolution anatomical information about complex structures such as atria and pulmonary …

Non-invasive Cardiovascular Magnetic Resonance Imaging in Patients with Ischemic Heart Disease
Cardiovascular disease remains a significant cause of premature death and disability in developing nations, with an increasing need for early and accurate diagnosis to limit downstream adverse events. By exploiting intracapillary deoxygenated haemoglobin to generate its signal, …

Predictors of diffuse myocardial fibrosis in HIV infected persons: A multiparametric cardiovascular magnetic resonance study
… now a chronic disease. With increasing survival, cardiovascular disease (CVD) in people living with HIV is increasing in the ART era, with a changing epidemiology that is now largely characterised by diastolic dysfunction. Our hypothesis was that ART would be associated with regression of …

Characterisation of phenotypes of inflammation, fibrosis and remodeling in chronic rheumatic heart disease using multiparametric cardiovascular magnetic resonance and autophagy markers
… pulmonary hypertension is the major source of cardiovascular morbidity and mortality in the young, predominantly in low- and middle-income countries (LMICs). We investigated the association of valve lesions in RHD with cardiovascular magnetic resonance (CMR) tissue characteristics and autophagy …

Cardiovascular magnetic resonance and right ventricular angiography in assessment of right ventricular volumes, function and wall motion abnormalities in arrhythmogenic right ventricular cardiomyopathy: a comparative study
… Criteria which include RV angiography (RVA) and cardiovascular magnetic resonance (CMR). There has been a dearth of studies to document the comparison of the performance of CMR and RVA, and none undertaken in Africa. The aim of this study was to compare CMR and RVA in the assessment of ARVC in …

Correlation of signal-averaged electrocardiogram and late gadolinium enhancement cardiovascular magnetic resonance in the detection of myocardial fibrosis in arrhythmogenic right ventricular cardiomyopathy and other myocardial disorders
… ventricular arrhythmias. The correlation between cardiovascular magnetic resonance (CMR) late gadolinium enhancement (LGE) and parameters of SAECG in ARVC is not known. Method. Thirty-five patients [median age 32 years (IQR 25 – 46)] referred to the ARVC Registry at Groote Schuur Hospital were …

The South African Cardiovascular Magnetic Resonance (SA-CMR) Registry: An Interim Analysis of Clinical Utility, Indications and Baseline Characteristics of Patients Undergoing CMR in a Single Centre in South Africa
Background Cardiovascular magnetic resonance (CMR) is a clinically useful imaging modality that is fast becoming a routine tool in clinical practice. In 2013, the results of the first multi-national registry, EuroCMR, were published. The study highlighted the clinical significance and impact of CMR …

Prenatal Cardiovascular Physiology and Early Neurodevelopment in Cyanotic Congenital Heart Disease
Advancements in infant cardiovascular surgery have resulted in a significant decrease in mortality of many newborns with congenital heart disease (CHD); however, neurodevelopmental delays and disorders (NDD) are common comorbidities. Studies have demonstrated delays in brain growth and maturation …
