Method for preparing teaching specimen of left ventricular outflow tract view of fetus suffered from congenital heart disease

Abstract

The invention relates to a method for preparing a teaching specimen of a left ventricular outflow tract view of a stillbirth suffered from a congenital heart disease. In the method, a free heart specimen is prepared after a selected artificially-labored fetus having a malformed heart is antiseptically treated; and in the left ventricular outflow tract view, the horizontal axis of the view is parallel to the long axis of the heart by taking a pulmonary conus as a start point of a cross section, the cross section is up to a superior vena cava through aorta ascendens and down to the apex of the heart through an anterior interventricular groove. The obtained apical four-chamber view specimen has the advantages of integrated and complete structures of all parts, no damage to microstructures in the heart, the same shape as that in a real living body, and capability of meeting the requirements of medical teaching and practice and the like, and is suitable for schools, hospitals or medical research institutes.

Description

technical field [0001] The invention relates to a method for preparing teaching specimens, in particular to a method for preparing teaching specimens for fetal congenital heart disease left ventricular outflow tract section. Background technique [0002] According to reports, children with congenital heart disease account for 8% to 12% of babies born in my country, which means that 120,000 to 200,000 children with congenital heart disease are born in my country every year. About 20% of children with congenital heart disease have no therapeutic effect or die early after birth. Bring endless pain. Ultrasonography is almost the only option for prenatal imaging diagnosis of fetal cardiac malformations. Therefore, carrying out fetal heart ultrasound examination is an important part of prenatal ultrasound monitoring and predicting fetal health. It is in line with my country's national policy of improving the quality of birth population and reducing low-age mortality. [0003] Fet...

Problems solved by technology

[0004] Although most sonographers now have a good foundation in ultrasound medicine and years of experience in ultrasound diagnosis, the basic theory of ultrasound diagnosis of the fetal heart is relatively weak, and they lack understanding of the standardized section and anatomical structure of the fetal heart. The content is unclear and blind inspection, the left ventricular outflow tract section can reflect the special heart structure of ventricular septal defect and right ventricular double outlet congenital heart disease, so the teaching specimen of the left ventricular outflow tract section of fetal congenital heart disease can be intuitively Reflecting the special structure of the heart of ventricular septal defect and right ventricular double outlet congenital heart disease, providing reference for teaching and research
