cave: der Ostium secundum Defekt ist ein Defekt des Septum primums:

An ostium secundum ASD most often occurs as the result of a true deficiency of septum primum tissue; it is the most common form of a true ASD. The superior and posterior margins of the defect are composed of the septum secundum, the anterior margin is composed of the AV canal septum, and the inferior margin is composed of the septum primum and left venous valve of the inferior vena cava.18 These defects can vary in shape and can be elliptical or round (Figure 8). With large ostium secundum defects, the septum primum is often nearly or completely absent (2)
