What is the purpose of the Amplatzer Septal Occluder device?

To close a PFO
To dilate a narrowed chamber
To replace a defective valve
To support a weakened septum

The correct answer is: To close a PFO

The Amplatzer Septal Occluder device is specifically designed for closing a patent foramen ovale (PFO), which is an opening between the right and left atria of the heart that fails to close naturally after birth. This device is a key tool in interventional cardiology for treating certain conditions associated with a PFO, such as paradoxical embolism or transient ischemic attacks (TIAs). By placing the occluder in the atrial septum, it effectively seals the PFO, preventing blood from flowing between the atria and reducing the risk of complications linked to the physiologic shunt. Other options such as dilating a narrowed chamber, replacing a valve, or supporting a weakened septum involve different therapeutic approaches and devices altogether, which do not align with the specific function of the Amplatzer Septal Occluder.
