A2 - Wong, Pierre C. PY - 2018 T2 - Practical Neonatal Echocardiography AB - This chapter discusses the use of the Doppler principle and the modified Bernoulli equation for the assessment of gradients and regurgitations caused by stenotic or insufficient valves, as well as the evaluation of physiologic or pathologic communications within the circulatory system. These principles are applied to clinical bedside decision making in the context of neonatal functional echocardiography.
