Mildly elevated circulating unconjugated bilirubin (UCB) is associated with protection against hypertension and ischemic heart disease. We assessed whether endogenously elevated bilirubin in Gunn rats modifies cardiovascular function and resistance to ischemic insult. Hearts were assessed ex vivo (Langendorff perfusion) and in vivo (Millar catheterization, echocardiography), and left ventricular myocardial ...

Part of the myocardial damage occurring during cardiac surgery is a consequence of reperfusion injury. Cyclosporine, a potent inhibitor of the opening of the mitochondrial permeability transition pore, attenuates reperfusion injury in patients with acute ST-segment elevation myocardial infarction. This study investigated whether the administration of cyclosporine just before the ...

Aortic insufficiency (AI) following rotary left ventricular assist device (LVAD) implantation is an increasingly common problem with inadequately defined treatment options. Percutaneous transcatheter (PTC) closure of the aortic valve has been described as a potential non-surgical approach. Alternatively, we present a case of decompensated heart failure due to de novo ...

Calcified aortic stenosis is a condition that affects the valve and the myocardium. As the valve narrows, left ventricular hypertrophy occurs initially as an adaptive mechanism to maintain cardiac output. Ultimately, the ventricle decompensates and patients transition towards heart failure and adverse events. Current guidelines recommend aortic valve replacement in ...

We present a case of a patient who, after correction of tetralogy of Fallot (TOF), experienced runs of ventricular tachycardia (VT). Mapping of the aortic root showed that the critical component of the reentry was located within the noncoronary cusp. The potential explanations of such an unusual isthmus location may ...

Early detection of left ventricle (LV) systolic dysfunction is essential for management of patients with aortic stenosis (AS). Two- dimensional speckle tracking derived global longitudinal peak strain (GLPS) is more sensitive than ejection fraction (EF) but requires good image quality and is not easily accessible. The aim of the study ...

In patients on dialysis, the most common cause of death is cardiovascular disease. This is caused, at least in part, by excessive vascular calcification. Studies that have examined coronary calcification have been published, but these measurements require expensive equipment. Here, we used computed tomography to determine aortic calcification and evaluated ...
