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
Detection of intracardiac shunts is imperative to prevent paradoxical thromboembolism and heart strain from a shunt’s additional flow. Multiple modalities are used to detect shunts, including echocardiography, MRI, CC, and nuclear modalities. Echocardiography is the initial imaging modality for ASD, VSD, and PDA. In ASD and VSD, TEE, 3DE and MRI play a complementary role and can help to determine the suitability for percutaneous closure. Percutaneous closure is being increasingly used for ASD and PDA repair, while percutaneous VSD repair still remains in the experimental stage.
