``In simplistic terms, a PFO is the result of incomplete closure of atrial tissue, whereas an ASD is the result of complete absence of such tissue between the right and left atrial heart chambers.''
It is possible to differentiate an ostium secundum ASD from a PFO on CT images. Ostium secundum ASDs are a direct communication between the two atria, whereas a PFO defect is a tunnel of variable width and length between the two atria 5. The PFO flow is usually left to right but can be bidirectional.
Conclusions: Atrial septal defects and PFOs can be differentiated using the characteristic direction of the contrast jet from the left to right atrium and the appearance of the atrial septum on coronary CT angiography.
Patent foramen ovale (PFO) is a common congenital atrial septal defect with an incidence of 15–35% in the adult population.
The foramen secundum or ostium secundum is a foramen in the septum primum, a precursor to the interatrial septum of the human heart. It is not the same as the foramen ovale, which is an opening in the septum secundum.
The reported prevalence of patent foramen ovale (PFO) in the general population is variable. It ranges between 8.6 and 42% ing to the population studied and the imaging technique used.
An ostium secundum atrial septal defect (ASD) is an abnormally large opening in the atrial septum at the site of the foramen ovale and the ostium secundum. There are several types of ASDs; these include ostium secundum, ostium primum, sinus venosus, and coronary sinus ASDs, and patent foramen ovale.
While ASD represents a true defect in the fossa ovalis region with varying magnitude and direction of intracardiac shunting depending on the size of the defect and relative filling pressures of the ventricles, PFO is as a result of an incompetent fossa ovalis valve with up to 25% prevalence in the general population 1 ...
An ASD is a congenital heart defect, a condition that you are born with. PFOs can occur only after birth when the foramen ovale fails to close. Our adult congenital heart program is one of the few programs in the nation that cares for the complex needs of adult congenital heart patients.
PFO/ASD closure is a routine procedure to close holes in the upper chambers of the heart. Before the procedure, you will undergo a cardiovascular imaging test, such as an echocardiogram, to pinpoint the shape and size of the hole and make sure no other defects are present.
