Re: Sp>En bisectriz (coronary artery)

[Guest guest]

Hello Marla (and thanks Guy, and Sharon for your help)

I'm afraid I haven't been able to hammer the nail home. I found the

following, which ties in with what said.

http://www.emedicine.com/PED/topic2506.htm

.. . .

The Cx coronary artery courses along the left AV groove, around

the obtuse margin, and posteriorly toward the crux of the heart.

Should the Cx coronary reach the crux of the heart and supply the

posterior descending coronary artery, the left coronary system

would be termed dominant. This occurs in approximately 10% of

patients. Atrial branches may arise from the Cx coronary artery

and supply the sinus node in 40% of patients. Obtuse marginal

branches arise from the Cx system to supply the posterolateral

aspect of the left ventricle. In an estimated 70% of patients, a

coronary branch (termed ramus medianus, intermedius, or

intermediate branch) arises early off the left coronary system to

supply an area between diagonal branches from the LAD and

obtuse branches from the Cx systems.

.. . .

That's not conclusive, which is why I asked whether anyone could confirm

that this intermediate branch is the same as bissectrice or bisectriz.

Sorry not to be able to give a more conclusive answer.

Good luck

Owen

Don't know if this helps or complicates things:

http://www.angiocardio.com/anatomie.htm#Anatomie

Tronc - Il s'agit de l'ostium coronaire gauche se situant à

la face postérieure du sinus gauche. Il donne le plus

souvent 2 branches : IVA et CX, voir une 3ème

branche: bissectrice.(non visible sur le schéma).

Still no idea what this could be. A particularly large septal

perforator, maybe?

Dear Owen, and listmates,

I've just come across the same term (apparently) in

a Spanish discharge summary (after coronary bypass

surgery) -- reference is made to a saphenous vein used

to revascularize the " bisectriz " (the LAD and the distal

right coronary arteries were also revascularized).

From the references I've found googling in Spanish,

it appears that this may be a branch of the LAD, but

I can't find anything that I feel would qualify as an

equivalent in English. I checked out the URL that Guy

sent in response to your question, Owen, according to

which this " bisector " would be an occasional third branch

off of the left main coronary artery, along with the LAD and

the circumflex. Did you come up with anything credible for

this in English, or get any other replies (I saw 's

response, but still didn't arrive at anything in E)?

Any help appreciated (deadline 8 AM tomorrow!),

Marla
