Abstract This chapter describes the emerging role of cardiovascular magnetic resonance (CMR) in the assessment of neonatal hemodynamics. While at the time of publication this approach remains in its infancy,…
Abstract Two-dimensional speckle tracking echocardiography (2DSTE) is a non-Doppler technique that applies computer software analysis of images generated by conventional ultrasound techniques to calculate parameters of motion (displacement, velocity) and…
Abstract There is growing controversy in the field of neonatal hemodynamics about the diagnosis and treatment of neonatal cardiovascular compromise in the very preterm infant. Accordingly, fundamental questions such as…
Abstract The decision to provide circulatory support to newborn infants is predominantly based upon a reliance on blood pressure (BP) values, typically by targeting mean BP values, which serve as…
Abstract The assessment of myocardial performance and hemodynamics in term and premature infants is gaining considerable interest and has led to improvements in our ability to assess the neonatal heart…
