My sister was just told she had this. I tried to google it and got no where. So does anyone know what this is? I know what the two words seperated are but that doesn't help.

My ~only~ guess is that she had some sort of aortic transplant done. Since it is confusing to both of you ... err ... maybe she didn't. Aortic valves can be replaced with mechanical devices or bovine valves. One of my family members just had this surgery last week, so that's all I know about it.

Sounds as though she means she had a xenograft done (read about it here: http://circ.ahajournals.org/cgi/content/full/110/11_suppl_1/II-74 )

It just means that they made a new valve based on animal tissue and implanted that. The prefix "xeno" just means "foreign" or "not the same as" i.e. it wasn't of human origin.

Your sister had heart surgery????? I suspect that she's referring to the type of valve replacement she had (aortic valve) and that it is a bovine (cow) pericardial graft.

If this is the case, a surgeon will generally use a porcine valve, a bovine valve or a cadaveric donor (human) valve in children and women of childbearing years. The option of a mechanical valve is deferred for them because it requires the patient to forever take blood thinners. Biological valves are the way to go. I'm a little surprised though, as the standard of care as of late in cardiac valve replacement is a Ross Procedure. That's where the c-t surgeon will take the patient's pulmonary valve and put it in the aortic position, and then replace the pulmonary valve with a graft. The Ross Procedure is superior because it uses an autograft or a stentless porcine valve that can support itself -- this is for young patients or athletic older patients who are still very active.

If this is actually what's gone on (or is about to go on) with her, here's some more information for you:

It helps to have access to the right places....anyway here you go

SUMMARY: The term "bovine arch" is widely used to describe a common anatomic variant of the human aortic arch branching. This so-called bovine aortic arch has no resemblance to the bovine aortic arch. We describe the most common human aortic arch branching patterns and compare these with the bovine aortic arch.

Introduction

Introduction

References

One of the most widely used misnomers in the medical literature is that of the "bovine aortic arch" in humans.1,2 This term refers to a common anatomic configuration of the aortic arch. By its name, the bovine aortic arch in humans would presumably resemble the aortic arch branching pattern found in the family of ruminant animals, including cattle and buffalo. However, the bovine aortic arch configuration ascribed to the most common human aortic arch variants bears no resemblance to the aortic arch branching pattern found in cattle. We describe the specific anatomic appearance of human and bovine aortic arch branching patterns and propose a simple nomenclature scheme that should supplant the use of the term "bovine aortic arch" in humans.

There is much more, follow the link I think you should be able to get in.

OK, sub4hire wins that one. Guess I'll stick to medical microbiology and infectious diseases.....

Yep, and a bovine conduit graft containing the a-valve and the arch is generally what's used for transplant......

(It's what I do for a living....)

No winning involved. Just trying to help. I do have access to medical sites...studies...etc. Because of my career...which isn't being an MD. I did a search.
Generally it is pretty comical the ideas people throw out as fact in these medical threads.
