Heart defect teaching aid

A teaching aid for sonographic analysis of the blood flow through a defective heart and in combination with a sonographic device comprising:

• a human form having a hollow chest cavity;
• a plurality of heart models, each dimensioned and configured so as to represent a different structural heart defect;
• said structural heart defect replicates a disorder selected from the group consisting of a first example of a Partial Anomalous Pulmonary Venous Return, a second example of a Partial Anomalous Pulmonary Venous Return, a first example of a Total Anomalous Pulmonary Venous Return, a second example of a Total Anomalous Pulmonary Venous Return, a third example of a Total Anomalous Pulmonary Venous Return, a fourth example of a Total Anomalous Pulmonary Venous Return, a Mitral Valve Atresia, an Atrio-ventricular Canal, a Transposition of the Great Vessels, a Tetrology of Fallot, a Truncus Arteriosus, and an Ebstein's Anomaly;
• each of said heart models having heart walls and internal valves being disposed in said hollow chest cavity separately a circulatory system removably attachable to each of said plurality of heart models;
• an opening in said human form through which each said heart model is insertable into said hollow chest cavity;
• and
• a sonographic device for analysis of the blood flow through at least one of said defective heart models.
