Regarding The David Procedure
Regarding The David Procedure
It might be helpful to mention that the David procedure and modifications of it that other surgeons have developed essentially address surgery of the aortic root and allow various options for the aortic valve - sparing, repairing, or replacing. This is different from aortic surgery where a composite graft is implanted. A composite graft type of surgery is an "all in one" replacement of the aortic valve, the root, and some part of the ascending aorta as needed. With the David procedure, the valve is separate from the Aortic graft, so there are more options.
My husband's aortic surgery was a modified David procedure. In his case, they examined his Hall-Medtronic mechanical valve, which had been in place for 11 years, to be sure that it was still good. It was, and so it was "spared". The other point about his surgery was that the coronary arteries were left attached to his native aortic tissue. I know of others who have had a modified David procedure and their valves were either spared or replaced by bovine pericardial tissue valves. Bovine pericardial tissue valves have been implanted long enough now to have very good reports regarding their long term durability in the medical literature.
Mike, the bright side of all this is that the aortic aspect of your first surgery went well, and altho' your valve needs to be addressed, you will soon have a great one made of bovine tissue!
Mainframe, since you are/were bicuspid, there is potential of your aorta dilating in the future, as was the case with my husband. I hope you can work with your doctors to monitor your aorta going forward.
