for teaching

3D printed heart displays the internal structures of all chambers. The superior and inferior vena cava enter the right atrium, revealing the pectinate muscles of the auricle and the nearly translucent fossa ovalis. Right Atrium and Ventricle The right atrioventricular (tricuspid) valve with its three cusps is exposed, along with chordae tendineae and papillary muscles. The conus arteriosus leads to the pulmonary semilunar valve, and the right coronary artery continues posteriorly to the posterior interventricular artery. Left Atrium and Ventricle The pulmonary veins enter the left atrium, and the left atrioventricular (mitral) valve with associated chordae and papillary muscles is visible. The left ventricle shows well-developed trabeculae carneae, and the aortic semilunar valve sits at the base of the aorta. Coronary Arteries The left coronary artery gives rise to the left anterior descending, diagonal, ramus intermedius, and circumflex branches. The circumflex passes near the coronary sinus, while the left anterior descending penetrates the myocardium and emerges near the apex.
