I have been put on Beta Blockers (Atenolol) as well since the Op. I started on Metoprolol in hospital and then at home twice a day but changed to Atenolol for a 'once a day' fix. I had never suffered from high blood pressure previous to the event. The Cardiologist has told me that the Beta Blocker will 'prevent' the blood pressure from getting to a higher level and possibly putting additional strain on my descending aorta and the graft of the ascending aorta. It also helps to control heart rate. All have been working well since the Op though I still have occasions when I get a little light headed at times.
The advice I have received from my Dr's is no heavy weightlifting anymore, though light weights are fine as long as I monitor my blood pressure. During my Cardiac Rehab Program they found my Blood Pressure actually decreased most of the time after lifting light weights. No more 110kg bench press though

As for Scuba Diving, I too am getting conflicting advice. Some people say it shouldnt be a problem, others are saying that a thoracotomy basically excludes me from further diving. I am planning to speaking to the Dr that runs the local Hyperbaric Chamber who specialises in Dive Medicine to confirm before I finally give up my dive licence.
If anyone else has any advice on the Diving side of things, it would be great to hear from you.
As for the Aorta being wrapped in Dacron, I seem to remember reading about this in my research, but I think it was more, the dacron was used to replace the damaged section of aorta, but that section of aorta was not removed, but wrapped back around the dacron, I could be wrong though.
This is an awesome online resource I found not long after my op and I needed to know what had been done to me.

Basically steps out the entire process, from diagnosis to the surgery to the recovery. Awesome find I thought.
