Assessing cardiac function in the single ventricle circulation: Kinetic energy ejection fraction
نویسندگان
چکیده
Background Those with single ventricle circulations often have a normal ventricular volumetric ejection fraction (VV EF) which is not in keeping with their symptoms and prognosis. Recently four-dimensional flow (4Dflow) magnetic resonance imaging (MRI) has been used to extract parameters of intra-cardiac kinetic energy (KE). There has been recent interest in measuring ventricular KE in health and disease to see if this could provide an additional tool in the assessment of ventricular function. We propose a new simple measure of ventricular function based on kinetic energy, the kinetic energy ejection fraction (KE EF), and assess its usefulness in patients with single ventricle circulation.

Introduction: Cardiovascular abnormalities have been reported in liver cirrhosis (LC). In these patients, cardiac symptoms and physical signs occur as the liver functions worsen. Cirrhosis is associated with hyper dynamic circulation and beta-adrenergic system changes responsible for the cardiovascular abnormalities. The purpose of the present study was to explore the echocardiographic findi...

Background Despite different aetiology of myocardial damage in dilated cardiomyopathy (DCM) and ischaemic cardiomyopathy (IHD), cardiac remodelling occurs in both, culminating in the end result of a dilated left ventricle with impaired function. Cardiac remodelling is a complex process in which numerous cellular, mechanical and flow processes become deranged. Insights into changes of multidimen...

BACKGROUND Quantitative assessment of ventricular volumes and mass in pediatric patients with single-ventricle physiology would aid clinical management, but it is difficult to obtain with 2-dimensional echocardiography. The purpose of the present study was to compare matrix-array 3-dimensional echocardiography (3DE) measurements of single-ventricle volumes, mass, and ejection fraction with thos...
