Alex, Glad to hear you are home and doing well.
At 8 years old, something about turning blue from time to time freaked my parents and doctors out.
My (this time around) surgeon told me post surgery that I had been born with a uni-cuspid valve, the reason for my first ride in 1968. At that time they had few fixes for children so near as he could tell they must have pushed a pinky finger through my AV to open it somewhat. At that same time they repaired 2 coarctations in my ascending aorta, a surprise found during my second surgery. I always knew I would have a second surgery at some point as an adult. I got by for 40 years on the pinky finger fix.
You'll get use to the clicking. Early on it kept me awake on occasion but it doesn't anymore. It's when you stop hearing it that you worry!
