Females constitute 65% to 75% of patients with secundum ASDs, but the gender distribution is equal for sinus venosus and ostium primum ASDs. The PFO is an oblique orifice in many .It is some times refered to as tubular PFO . Sinus venosus ASD can be subdivided into superior vena cava type and inferior vena cava type. Septum primum defects appear to be more common than septum secundum defects. Before the septum primum and endocardial cushions fuse, perforations develop within the cephalic portion of the septum primum through apoptosis, creating a large window known as the ostium secundum.

A defect in the ostium primum is occasionally classified as an atrial septal defect, but it is more commonly classified as an atrioventricular septal defect. Ostium secundum defects are associated with pediatric syndromes such as Noonan, Treacher-Collins, and thrombocytopenia-absent radii syndrome. Ostium secundum defects account for more than 80% of all ASDs 5 and occur twice as often in female patients. Because the atria expand to both area of the truncus arteriosus, a collapse is created within the atria to merely the suitable of septum primum. propos de nous; Conditions de prlvements; Services What is ostium secundum, what are This perforation, the second opening in the septum primum, is named ostium secundum.
