Background Delineation of diseased and normal tissue is fundamental to identifying cardiac pathology. Studies suggest that parametric extracellular volume fraction (ECV) imaging is superior to conventional delayed enhancement for detection of diffuse, global myocardial disease. Conversely, the sensitivity of ECV for the detection of focal disorders is(More)
Background The efficacy of current and novel heart failure therapies is likely related to viability that denotes the presence of cardiac reserve. Previous studies assessed viability mostly on a segmental rather than patient level, and included hypokinetic segments, which by definition−given residual contractile function−are viable. Additionally, studies(More)
BACKGROUND AND AIM OF THE STUDY Despite advances in mitral valve repair techniques, including robotic surgeries, few studies are available on predicting mitral annuloplasty ring size using echocardiography. Furthermore, these studies either had limited accuracy or else required the use of three-dimensional transesophageal echocardiography (3D-TEE), an(More)
BACKGROUND Orthotopic liver transplantation (OLT) is a major operation, causing cytokine release and other inflammatory responses that can contribute to postreperfusion syndrome occurrence. During the systemic inflammatory response syndrome, increased lactate levels result from excessive cytokine production despite normal oxygen delivery and carbohydrate(More)
Background Prior studies have established that myocardial scarring increases mortality even without overt symptoms of irreversible injury, for example due to unrecognized myocardial infarction (UMI) in patients with coronary artery disease (CAD), or replacement scarring in non-ischemic cardiomyopathy (NICM). Previous studies have also established that scar(More)
