Closure of Atrial Septum Defect and Patent Foramen Ovale (PFO)

Atrial septum defect (ASD) and patent foramen ovale (PFO) are two different conditions that refer to anatomical openings between the chambers of the heart. ASD refers to a hole or opening in the septum in the center of the atria (atria). This can cause blood to back up from the left atrium into the right atrium. Patent foramen ovale is a congenital condition and occurs when a temporary opening between the heart chambers fails to close during fetal circulation in the prenatal period.

One method used to treat these conditions is transcatheter closure. ASD closure is usually performed with a catheterized device. The catheter carries a device designed to close the hole between the atria, usually entered through the groin or thigh. This device is left in place to cover the hole and restore normal function of the heart.

Patent foramen ovale closure is similarly performed with a catheter. The catheter is usually inserted through the groin or thigh and carries a device used to close the patent foramen ovale. This device closes the opening between the atria, allowing normal circulation.

These transcatheter interventions offer a less invasive option than surgery and usually have a short recovery time. However, as each patient’s situation is different, the treatment plan should be individualized according to the patient’s characteristics and condition. These procedures are usually performed by a team of specialists, such as cardiologists and cardiovascular surgeons.
