What does it meant to have a pfo closure procedure?

Close hole in heart: There is a connection between the left and right sides of the heart before you are born which normally closes at birth. Sometimes it does not close. It used to require surgery to close that hole but now a device can be put through the hole by putting a catheter (tube) into the heart through a vein in the leg. The device then is pushed through the hole. The device springs open and closes the hole.

Closing a hole : A PFO is a hole in the heart that is nessecery during the fetal circulation, that closes sortly after we are born. In some people it remains open and can cause serious problems. The opening is closed most commonly by a cardiologist with out the need of surgery. In some situations an operation ( open heart surgery) is needed to close the hole. It is a very safe proceedure in experienced hands.
