This soft, realistic partial heart has a non-patent right atrium and ventricle. The left atrium and ventricle are patent, detailed, and sectioned for visualization of the left ventricular outflow tract (LVOT). The heart is a single-color casting. The exterior is highly detailed, as are the interiors of the left atrium and ventricle. This model is an excellent demonstration aid for mitral and aortic valve implantation strategies.
