  2. Atrial septal defect - Wikipedia

    en.wikipedia.org/wiki/Atrial_septal_defect

    It involves a patent ostium secundum (that is, a patent foramen secundum). The secundum atrial septal defect usually arises from an enlarged foramen ovale, inadequate growth of the septum secundum, or excessive absorption of the septum primum. About 10 to 20% of individuals with ostium secundum ASDs also have mitral valve prolapse. [5]

    Meanwhile, a hole appears in the upper area, called the ostium secundum, or “second opening”. Now, we also have the septum secundum which grows downward just to the right of the septum primum, and covers the ostium secundum like a curtain, leaving a small opening called the foramen ovale, and essentially creating a makeshift valve that ...

    The ostium primum atrial septal defect is a defect in the atrial septum at the level of the tricuspid and mitral valves. This is sometimes known as an endocardial cushion defect because it often involves the endocardial cushion, which is the portion of the heart where the atrial septum meets the ventricular septum and the mitral valve meets the tricuspid valve.

  5. Foramen secundum - Wikipedia

    en.wikipedia.org/wiki/Foramen_secundum

    Foramen secundum atrial septal defects are the most common atrial septal defects. This defect can arise as a result of defects of the septum primum and the septum secundum. For the septum primum, the problem can arise as a result of excess resorption of the septum during the process of apoptosis in order to form the foramen secundum.

  9. Foramen ovale (heart) - Wikipedia

    en.wikipedia.org/wiki/Foramen_ovale_(heart)

    Some embryologists postulate that the ostium secundum may be formed through programmed cell death. [4] The ostium secundum provides communication between the atria after the ostium primum closes completely. Subsequently, a second wall of tissue, the septum secundum, grows over the ostium secundum in the right atrium. Blood then passes from the ...
