So, my cousin told us once that You don't worry about the statistics until YOU ARE a statistic. Today, I started to wonder what are the chances of having Addi and her heart. So here are the statistics I found on various medical websites.

8 in 1,000 newborns have Congenital Heart Defect (CHD). Addison is one of those 8. There is a 0.8% chance of that. That would be 8000 out of 1 Million.

A VSD (hole in the heart) is the most frequent of the various types of CHD (25%-30% of all CHD). Approximately one infant in 500 will be born with a VSD. Addison is the one in 500. There is a 0.2% chance of that. Aside from that, a Straddling tricuspid valve is another uncommon anomaly that is associated with a VSD. That would be 2000 out of 1 Million.

So, back to those same 8 in 1000; 8–11 percent have coarctation of the aorta (Narrow aorta). That makes it a .064%-.088% chance that someone will have that. And guess what? Addison has that.That would be 640 out of 1 Million.

Heart block following cardiac surgery is seen in 1% of patients. So, Addison is the 640 in a million who has a coarctation and one of 6 of those kids who gets postoperative Heart block . Addison has that.That would be 6 out of 1 Million.

The prevalence of third-degree AV block is 0.02%. Only 200 out of 1 Million have a permanent pacemaker to cure the heart block... Addison has that.

The prevalence of postoperative of chylothorax is 0.85%. So, Addison is the 640 in a million who has a coarctation and one of 5 of those kids who getspostoperative of chylothorax. Addison had that.That would be 5 out of 1 Million.

Combine all this together and Addison is truly 1 in a million!
