Cardiac resynchronization therapy is an established treatment modality in heart failure. Though non-response is a serious issue. To address this issue, a good understanding of the electrical activation during left bundle branch block, biventricular, as well as right- and left ventricular pacing is needed. This way by interpreting the 12-lead electrocardiogram, possible reasons for suboptimal tr...
AIM The mechanisms of cardiac dysfunction in limb girdle muscular dystrophy 2I (LGMD2I) are unclear. This study assessed deficits in cardiac morphology, function, and metabolism quantitatively in patients with a confirmed genetic diagnosis of the homozygous c.826C > A FKRP (fukutin-related protein) mutation, using a comprehensive magnetic resonance (MR) examination. METHODS AND RESULTS Ten pa...
Cardiac cells are organized in vivo in a complex tridimensional structural organization that is crucial for heart function. While in vitro studies can reveal details about cardiac cell biology, usually cells are grown on simplified two-dimensional (2D) environments. To address these differences, we established a cardiac cell culture composed of both 2D and three-dimensional (3D)-organized cells...
Cardiac involvement is very frequent in patients with chronic kidney disease on dialysis. Kidney transplantation results in reducing morbidity and mortality compared to patients on dialysis. The objective of this review was to address the effect of renal transplantation in cardiac structure and function assessed by echocardiography. Since the 1980s, studies have demonstrated a trend towards imp...
Cardiac magnetic resonance (CMR) imaging has emerged as an important non-invasive cardiac imaging modality. A versatile technique, it has the potential for comprehensive evaluation of coronary artery disease (CAD): cardiac morphology and function, myocardial perfusion, myocardial viability, coronary artery visualisation and atherosclerotic plaque characterisation. Some of these techniques--vent...
Background Cardiac involvement in systemic lupus erythematosus (SLE) is a common complication and is associated with a considerable morbidity and mortality in these patients. As affected individuals often present with subclinical or nonspecific symptoms the betimes confirmation of cardiac manifestations is challenging. Cardiovascular magnetic resonance (CMR) with late gadolinium enhancement (LG...
Today, an increasing incidence of severe complications of cardiac malformations in adult patients must be expected since the life expectancy of such individuals is prolonged due to improved management. A 32-year-old woman with corrected transposition of the great arteries (CTGA) was admitted to the intensive care unit because of cardiac decompensation. Information provided by multiplane two-dim...
Elucidating cardiac evolution has been frustrated by lack of fossils. One celebrated enigma in cardiac evolution involves the transition from a cardiac outflow tract dominated by a multi-valved conus arteriosus in basal actinopterygians, to an outflow tract commanded by the non-valved, elastic, bulbus arteriosus in higher actinopterygians. We demonstrate that cardiac preservation is possible in...
Background: Although MRI has long been used for cardiac imaging, significant improvements in MRI scanners for cardiac specific pulse sequences have only been commercially available since the late 1990’s. Cardiac MRI is a complex and difficult examination that needs not only state-of-the-art MRI scanners, but also staff that is experienced with performing cardiac MRI studies. The main advantages...
