The most common defect is the secundum atrial septal defect 80%, which occurs when the ostium secundum is too large for complete coverage by the septum secundum Fig. 127-7. Failure of postnatal fusion of the septum secundum to the septum primum results in a persistent slitlike communication known as a patent foramen ovale PFO. Best visualized on subcostal four-chamber view of the heart. Ostium secundum ASD's appear as a larger than expected area of dropout in the central portion of the septum secundum in the vicinity of the foramen ovale or as a deficient foraminal flap septum primum that fails to cover the entire foramen ovale. Also called 'Partial AV Septal Defect' A defect is present in the lower part of the "Atrial Septum" the partition separating the Atriums. This allows red blood to pass through into the right side of the heart, leading to enlargement of the right ventricle and excessive flow in the lung circulation.
The foramen secundum from Latin, meaning 'second opening' is formed from small perforations that develop in the septum primum. The septum primum is a septum that grows down between the single primitive atrium of the developing heart to separate it into left and right atria. A second septum septum secundum develops downward and to the right of the septum primum. With its semilunar edge, the septum secundum and the remains of the septum primum form the foramen ovale. Within the left atrium, the septum primum forms the flap valve of the foramen ovale that allows blood flow from right atrium to left atrium in the fetus. 15/01/2018 · Approximately 2,000 babies are born each year with Atrial Septal Defect ASD, a condition where a child has an abnormally large hole between the chambers of the heart after birth.

Förmaksseptumdefekt är medfött och uppstår då de olika septa septum primum och secundum i det gemensamma förmaket under embryonalperioden inte utvecklas normalt. På grund av det lägre kärlmotståndet i lungkretsloppet jämfört med systemkretsloppet flödar blodet från det vänstra till det högra förmaket genom hålet i förmaksskiljeväggen. o Second orifice in septum primum o Covered by septum secundum Arises on right atrial side of septum primum Septum secundum grows caudally covers ostium secundum Forms the fossa ovalis In fetus o Does not completely divide atria o Leaves an oval orifice Foramen ovalae Covered, but not yet sealed, on left side by flexible flap of septum primum. Other types of ASD affect different parts of the atrial septum. Defects in the lower part of the septum, close to th Atrioventricular Valves e.g. Tricuspid valve are called 'Primum ASD' or Partial Atrioventricular Septal Defect. Go to Normal Heart.

|An ASD can result from • Defects of the septum between the right upper pulmonary veins and the cranial vena cava sinus venosus defect • Failure of fusion of septum primum with the endocardial cushions ostium primum defect, low in the atrial septum adjacent to the AV valves, a form of AV septal defect.||The ostium primum ASD is the second most common type. Although ostium primum defects may occur alone, they usually occur as part of a more complex congenital cardiac anomaly, the atrioventricular septal defect. The ostium primum ASD is located low in the atrial septum immediately adjacent to the atrioventricular valves.|

Dit type ASD komt doorgaans voor in het kader van een atrioventriculair septumdefect. het sinus venosus defect.

Patient 7: Primum ASD. Another rare type of ASD encountered in the adult is the ostium primum defect. When the atrial septum develops in the fetus, the first septum that arises, the septum primum, grows from the basal wall of the atria toward the apical wall toward the ventricles.
