ASD closure with oclluders and SVT ablation

[electrophysiologist]

Which is most appropriate is to ablate the SVT first and then insert the occluder or the other way round?

I could be wrong about this, BUT, I remember reading something a while back on precisely the same subject.  If I recall correctly, the ablation for SVT is performed first followed by the repair of the ASD.  If the problematic area is located on the left side of the heart, the defect itself is used to access that side instead of by transseptal puncture.  I also think I read where the two are performed during the same procedure, saving another trip to the OR.  Please don't hold me to this, but that;s what I remember reading.  I don't have an ASD, but the flaps of my atrial septum overlaps slightly and is not sealed, much like sliding doors.  My physician was able to thread the catheter through the overlap thus saving me from the puncture wound.  I'm guessing that your EP would follow a similar route thru the defect.

I think you may want to post this in the doctors forum rather than the members forum.  The participants here are mostly patients and wouldn't likely be qualified to answer your question.
