Text C. New Investigations on the Vascular Structure of the Heart
Great work on modern anatomy was begun in the 15th and 16th centuries. Such great men as Leonardo da Vinchi, Vesalius, Servet and Harvey did much to study the structure of the human body.
In the 20th century anatomy became an exact science. Scientists considered that no new discoveries could be made in this field.
But in 1968 Prof. Seraphima Samoilova, a surgeon — a student of Sergei Udin, who worked in Leningrad, began to study the heart vessels.
Anatomists always considered that the heart was mainly a muscular organ. The heart chambers, the valves, the muscular bands and the coats were well described. But not much was said about the heart vessels.
Seraphima Samoilova determined that the heart consisted of thin vascular tubes. Half of the heart weight was composed of the bands of vessels. She came to the conclusion that the heart was a dilated large vessel included in muscular tissues.
The structure of the heart as a band of vessels is very intricate [‘intrikit] (сложный) and varies with age and diseases.
Seraphima Samoilova included all the findings of her research work into the book called The Anatomy of Cardiac Blood Vessels.
This book was published in Leningrad in 1970. It helps surgeons to perform operations on the heart.
