ASDs, PFOs, and aortic dilation, oh my!

Hannah did fantastic yesterday during her echocardiogram and EKG.  They did end up sedating her using an oral sedation (she did NOT like the syringe in her mouth, my control-freak child).  She woke up out of the sedation really well, and she was fine for the rest of the day.  They warned us she might be a bit “tipsy” like a drunk, and she sure was.  But she was a “happy drunk” for a couple of hours, laughing at the strangest things.

We met with the Cardiologist this morning.  Hannah does NOT have an ASD (atrial septal defect), but instead they believe she has a PFO (patent foramen ovale).  It is something that is very common, almost 30% of the general population have one.  It can be left alone for the most part unless Hannah developes migraine headaches when she is older, then they can close it.  Otherwise it is just something that will be monitored but left alone!  Great news on that front.

However, they also noticed that Hannah’s aorta is slightly dilated.  This is of some concern, as if it continues to dilate, it could cause an aortic dissection (think John Ritter).   But for now, we are just going to monitor it and do another echo in 6 months.  There are three schools of thought on this:

1. It could be related to Hannah’s D409H genetic mutation, which when homozygous, is known to have the propensity for cardiac calcification issues.  Perhaps her never-before-documented combination could related to aortic issues? 
2. It could not even be related to Hannah’s Gaucher’s Disease, and it is just something “else” we need to keep an eye on.
3. It is just a normal variant for Hannah, and this is the size of her aorta.

In 6 months, we will have a better idea whether or not it is just a normal variant for Hannah or if it is indeed a cardiac issue that is going to have to be closely monitored over the course of her life.
