This is an advanced clinical text, extensively illustrated with color as well as black-and-white photographs, on the techniques of Doppler investigation in the analysis of early pregnancy and study of the fetal venous circulation. It also covers diagnostic criteria for fetal cardiac disease and how complications of pregnancy such as post-term pregnancy, fetal growth retardation, fetal anemia, diabetes, and non-immune hydrops affect the fetal cardiovascular system. As Dr. J.C. Hobbins, University of Colorado Health Sciences Center, says in his preface, The wealth of quality information that has been beautifully chronicled in this book has provided new insights into fetal physiology and the circulatory dynamics of various fetal conditions. . . . a very useful resource for the clinician and a spark for young investigators to pursue further some brand new concepts that have been touched upon in every chapter.
