Posts Tagged ‘proximal lad equivalents’

We do know about left main equivalent . Do we have a proximal LAD  equivalent ?

Proximal LAD lesions deserve a special attention and probably urgent intervention. Medical management is not an option in most  patients. (Proximal alone is not suffice , it should be critical as well )

But we have another issue on hand .What really is proximal LAD ? .

  1. First 5 Cm of LAD ? (LAD normally measure about  15cm so 1/3rd becomes proximal .How logical it looks  isn’t ?  )
  2. Before any  S1 or D1 ?
  3. Before any major S1 or D1 ?
  4. Septal branch is not considered at all  . A lesion is said to be proximal if it is before a major D1
  5. Some others may argue if there are  three major branch  distal to lesion it should be considered proximal.

Proximal LAD equivalents .

LAD first or second   bifurcation  lesions ( Medina1 1 1 , 1 1 0 , 1 0 1)

Mid LAD lesion with major D1 ostial  lesions

For  a super-dominant LAD  even  mid segment  lesion  can  be a   proximal equivalent (By area at jeopardy )

If LAD is giving collaterals  to LCX /OM  /  due to  associated  lesions ,   LAD lesion at any level  becomes  a left main equivalent .
