[HSF] 25 mm valve

[Otto Thaning]

Some advice please on the following:

58 year male presents with progressively severe angina on minimal 
provocation.

He has severe proximal LAD & diagonal stenosis, a completely occluded RCA. 
His Cx is an unobstructed vessel BUTarises from the Right coronary cusp. It 
is not possible to determine its course to the lateral LV wall territory, 
but it is a pristine vessel and has a large lateral wall territory that 
fills well and feeds also a large PDA retrogradely.

I plan to graft the LAD, Diagonal and the PDA. The question is what to do if 
the Cx has a course between the PA and the Ao?
