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 ...
Amplatzer PFO Occluder The Amplatzer occluder is the only device that has FDA approval for PFO closure in the context of cryptogenic stroke. It is made of two nitinol woven discs with integral Dacron patches and a fixed short waist (Figure 1).
The ASD closure device is designed to flatten against your septum and seal the hole. Immediately after surgery, the device stays in place because of the natural pressure in your heart. Over time, your heart tissue grows around the ASD closure device. You usually spend one night in the hospital before returning home.
Over 40 adults with ASD might face rhythm troubles, like atrial fibrillation, which could lead to stroke or lung pressure problems. PFO is usually less of a worry but can still cause strokes or mini-strokes when clots travel through to the brain.
PFO closure is usually considered to prevent recurrent embolic stroke/systemic arterial embolization, ASD closure is indicated in patients with large left-to-right shunt, right ventricular volume overload, and normal pulmonary vascular resistance.
CT diagnosis of PFO was defined as (1) a channel-like appearance of the interatrial septum (IAS) and (2) a contrast agent jet flow from the left atrium (LA) to the right atrium (RA). ASD was defined as (1) the IAS resembling a membrane with a hole and (2) a contrast jet flow between the two atria.
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.
Small holes between the upper chambers of the heart may be categorized as an atrial septal defect (ASD) or patent foramen ovale (PFO). 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.
Ingly, the PFO can be classified as large ( 4 mm), medium (3.9–2 mm), and small (<2 mm).
