PFO and atrial appendage closure

How our heart reacts to physical exertion

Holes in the heart are not uncommon and can be dangerous. Here you can find out how to close them. We will focus on the atria (ventricles) of the heart.

PFO and atrial septal defect (ASD) closure

In the womb, there is a connection with a flap-shaped hole between the right and left atrium of the heart. This small opening in the cardiac septum has the important function of supplying the unborn child with oxygen by allowing oxygen-rich blood from the mother's circulation to enter the child's circulation, bypassing the lungs which are not yet functional. Normally, this connection closes after birth. If this does not happen, it is referred to as a persistent foramen ovale (PFO). This connection can either remain completely open or only partially close.
As long as the pressure in the left atrium is higher than in the right, a persistent foramen ovale (PFO) or persistence of the PFO is not considered a disease. However, if small blood clots (e.g. from a leg vein) enter the left circulation through the PFO, this can trigger a stroke. For this reason, the presence of a PFO should be clarified using cardiac ultrasound in stroke patients. A connection with the occurrence of migraine attacks is also being discussed. A PFO can also lead to other restrictions.
A cardiac catheter is used to close a PFO. It is used to close the open connection with an umbrella (nickel-titanium alloy). By puncturing the inguinal vein, the umbrella can be inserted into the PFO in a folded state and implanted. The umbrella grows in within a few months and the PFO is closed.

An atrial septal defect (ASD) is a congenital defect in the wall between the two atria. There are different types of atrial septal defects such as the secundum ASD (ASD II) (most common, can also be closed with an umbrella like the PFO), a sinus venosus defect (closure with heart surgery) or an ostium primum defect (primum ASD, ASD I; closure with heart surgery).

Atrial appendage occlusion

The left atrial appendage (LAA) can be closed with an atrial appendage umbrella or an operation. This is intended to reduce the risk of stroke. This mainly affects patients with atrial fibrillation, which requires a complete blood thinning but cannot be taken regularly due to bleeding problems. A detailed assessment (cardiac ultrasound, possibly CT, rhythm consultation) and consultation are important before an operation.
Before, during and after the procedure, we are at your side with help and advice. This naturally applies to all heart operations. You will also receive our usual personal support and care during your stay in hospital.
