[HSF] Bicuspid aortic valve and dilated ascending aorta

[Jean BACHET]

Tom Martin is 300% right!

Dilated ascending aortas and/or aortic roots should be replaced in BAV patients whenever their diameter reaches 40 to 45 mm.
If some one needs  more scientific information here are two good papers, dealing with this topic:

 
Borger et Al. Should the ascending aorta be replaced more frequently in 
patients with bicuspid aortic valve disease? 
J Thorac Cardiovasc Surg 2004; 128: 677-83 

Von Kodolitsh Y et al. Predictors of proximal aortic dissection at the time of aortic valve replacement 
Circulation 1999; 100 (supp II) II: 287-94

> Sorry I have not responded to this earlier but I have been too busy doing redo complete sternotomies for patients that had previous bicuspid aortic valves replaced with "dilated" (4 cm) aortas. 
> That is supposed to be funny but in reality I just did a redo in a patient that had a bicuspid AVR several yrs ago and was refered to me with a 7 cm ascending. I actually see quite a few pts also that have had previous bicspid AVR's that come to us with acute dissections. Patients with bicuspid aortic valves and dilated ascendings have abnormal collagen and WILL have a problem in the future.
> My advice in this area is- at the minimum AVR plus ascending if the aorta is 4cm or greater and if the sinuses are significantly enlarged, do a root.
> As for the "mini" sternotomy or minimally invasive approach to the aortic valve my question is WHY!? There is no real benefit to the patient in any fashion and it is harder to do.
