This 3D print preserves the superficial anatomy of an isolated human heart along with the bases of the great vessels. All four chambers—atria and ventricles—are clearly visible, with pericardial reflections on the left atrium marking the positions of the transverse and oblique pericardial sinuses.
Coronary Arteries and Veins
The right marginal branch of the right coronary artery is visible exiting the fat-filled coronary sulcus, along with the posterior interventricular (posterior descending) artery within its sulcus. On the anterior side, the anterior interventricular (left anterior descending) artery and diagonal branches from the left coronary artery are clearly displayed. The terminal portion of the circumflex branch can be seen deep to the left auricle, alongside the great cardiac vein. On the posterior aspect, the coronary sinus collects all cardiac veins—great, middle, and small—and includes a prominent posterior vein of the left ventricle.
Heart Valves
At the bases of the ascending aorta and pulmonary trunk, the aortic and pulmonary semilunar valves are visible, providing a detailed view of the outflow pathways from the ventricles.
