Abstract
SHS investigation development is considered from the geographical and historical viewpoint. 3 stages are described. Within Stage 1 the work was carried out in the Department of the Institute of Chemical Physics in Chernogolovka where the scientific discovery had been made. At Stage 2 the interest to SHS arose in different cities and towns of the former USSR. Within Stage 3 SHS entered the international scene. Now SHS processes and products are being studied in more than 50 countries.
Abstract
The frequency of the different fetal septal defects and their presentation prenatally is described, including atrial septum defects (ASDs), ventricular septum defects (VSDs) and atrioventricular septum defects (AVSDs).

Image findings in the fetal period are presented alongside diagrams to aide comprehension of the ultrasound views. A brief summary of prognosis and postnatal course of these conditions is also included.
