Tough Calls: Case 1
The Super Floppy Aneurysmal Septum For PFO Closure
Imagine how you would work through each case. What equipment would you select and what would you do first? After having a go at it, see what our panel would do in the same situation. This exercise highlights the many possible approaches to a difficult problem. By seeing what others would do after thinking it through yourself, you will gain an understanding of the spectrum of approaches to a problem.

•Need 3D assessment – either with pre-procedure CTA or intra-procedure TEE
•Probably use 35 mm Amplazter PFO Occcluder
•Goal: Reduce R to L shunting so no longer hypoxic – do not have to eliminate all shunting.

I would use an Amplatzer PFO device with a large RA desk, 35mm to prevent embolization to the LA.

Right heart catheterization with balloon test occlusion/sizing of the PFO/ASD. Consideration for PFO device (Amplatzer PFO device versus Gore Cardioform Septal Occluder) versus Amplatzer Septal Occluder depending on findings on ICE and balloon sizing/approximation of the tunnel if present. Very redundant appearing foramen flap may be better with ASO or larger Amplatzer PFO device.

I would balloon size this PFO, even though I almost never do that. I suspect it will stretch quite a bit, given the septal mobility on echo. Would anticipate closing with an Amplatzer Septal Occluder (for its “self-centering”) that is the diameter of the sized PFO +0-2 mm. The proximity to the aorta doesn’t concern me too much for erosion; I think it would straddle the root well.

GA/TOE or ICE
Cross with MP catheter and deliver Amplatzer extrastiff to LUPV
Balloon size using 34mm Amplatzer sizing balloon
Aim to deploy 35mm Amplatzer PFO occluder.
Need to ensure stable prior to release- ideally, disks would splay on aortic ridge
I think PFO occluder likely to work better than ASO.
I would be wary regarding using a Gore device in this case (stability).
