Color injection into the coronary vesselsįor the injection into the coronary arteries (left anterior descending artery, left circumflex artery, and right coronary arteries), colored silicone KE24 (Shin-Etsu Chem. The heart was flushed with tap water to remove blood clots. The heart of a pig subjected to meat processing with no morphological abnormalities on macroscopic inspection was used. It is possible to produce a plastinated specimen of a porcine heart, cut off the suitable cross-section surfaces for standard echocardiographic images, and make a comparison while performing echocardiography. From this standpoint, the potential value of plastination is increasingly appreciated. The plastination method has been used to process cadaveric material and make it into dry, odorless, and durable specimens that can be handled without gloves. However, from among the other artificial models of the heart, it is difficult to find instructional materials suitable for students or beginners who have just begun to study echocardiography. Therefore, anatomic drawings, atlases, and models that correspond to standard ultrasound images are necessary to assist echocardiographic interpretation.
The precise spatial relationship of the components of the heart can be difficult to understand for students and beginners. However, its usefulness and the correct diagnosis depends on both the proper skills and the well-understanding of the heart. It is widely accepted that echocardiography is one of the non-invasive and very useful tools for diagnosing cardiovascular disease. Key wordsĮchocardiography, plastination, porcine heart Introduction The final specimens show the detailed structure of the heart, which provides students and beginners who are training for echocardiography a better chance of developing a three-dimensional understanding of the heart. In this paper, the method of producing plastinated pig heart specimens for learning echocardiography is described. Plastination has been known as an excellent technique that helps to keep anatomical specimens in a dry, firm, shape-preserved condition. However, the precise spatial relationships of the components of the heart can be difficult to understand. With recent developments in echocardiography, most operators need to be familiar with cross-sectional cardiac anatomy.
