Re: PFO closure
3D TEE is more accurate than 2D Tee. Do you know what type you had? I have read that the accuracy of the test and results, depends upon the skill of the operator. Some of the operators are cardiac anesthesiologists, and they learn how to do this procedure at seminars, and later take a test to become qualified.
I have read that sometimes there are artifacts in the images. I believe that they use one of a couple of techniques to increase the pressure inside the right atrium, in order for the flap to open, and enable them to see, or locate the hole. Normally the pressure is higher in the left atrium, and keeps the flap sealed off, or the hole closed. Maybe they had problems increasing the pressure inside the right atrium ???
Were you going to have the catheter based repair, or conventional surgery? What kind of problems has the PFO caused you? Sorry to be nosy. I know that when they cause problems, a stroke can occur. I wish you the best of luck.
