Introduction
The foramen ovale was a vascular shunt within the developing atria of the heart, two separate forms of foramen ovale closure; functional and structural. Functional closure begins at the first breath and is rapid. Structural (anatomical) closure is much slower and generally occurs before the end of the first year.

Abnormalities
ICD-11 LB20 Congenital Anomaly of Atrioventricular Valves or Septum
|
The term atrial septal defects (ASD) describes a group of common (1% of cardiac) congenital anomolies defects occuring in a number of different forms and more often in Females. Patients have been reported living to old age with forms of this cardiac abnormality.[2]
- patent foramen ovale - allows a continuation of the atrial shunting of blood, in 25% of people a probe patent foramen ovale (allowing a probe to bepassed from one atria to the other) exists.
- ostium secundum defect
- endocardial cushion defect involving ostium primum
- sinus venosus defect - contributes about 10% of all ASDs and occurs mainly in a common and less common form. Common ("usual type") - in upper atrial septum which is contiguous with the superior vena cava. Less common - at junction of the right atrium and inferior vena cava.
- common atrium
