The "H" in CHARGE - Heart
The following are the details of what we know about Raphael's heart.
Raphael's notable heart conditions consist of the following:
- "Mildly dilated right atrium" (This was noted in the preliminary report and removed in the final echocardiograph 26/5/2006)
- "Two small low velocity shunts (1.1-1.2 m/sec) across the inter-atrial septum, suggestive of ASD or PFO." (echocardiograph 26/5/2006). "There is a small L-R shunt across the inter-atrial septum, Vmax=1.3m/sec, suggestive of small ASD" ... "ASD/PFO" (echocardiograph 24/11/2006).
- "There is a left sided aortic arch. There is no evidence of a double arch." (MRI 18/12/2006)
- There is, however, an aberrant right subclavian artery." (MRI 18/12/2006)
The following is my simplified understanding of the terms and/or concepts listed above:
- Given that this finding was removed in the final report I assume that this dilation was so mild as not to be worth commenting on.
- An ASD (Atrial Septal Defect) is a type of defect that is commonly referred to as "a hole in the heart". It has been commented that this may in fact be a PFO (Patent Foramen Ovale), rather than an ASD, which is a common finding which may rectify itself with in the first few years of life.
- The left sided aortic arch is a blood vessel that pushes on the oesophagus slightly. Fortunately this is not repeated on the other side as well.
- An aberrant right subclavian artery is just a rare configuration in the rout of the right subclavian artery.
- No implication unless it is actually dilated
- This reports that Raphael has a small ASD/PFO that seems to have no practical consequences.
- I wonder whether the pressure on his oesophagus is partially responsible for his swallowing problems. A double arch could result in a ring around his oesophagus and trachea, choking him and preventing swallowing, but he does not have this.
- There are no practical implications of having an aberrant subclavian artery. It is only relevant to make sure that medial professionals are aware of the condition when procedures are being carried out in the area.
Raphael does not have any significant heart problems. The minor issues only seem to be relevant to anaesthetists and medical emergencies.
