Thanks for the excellent case presentation.

It seems that HDR is the same as modified carlino? Can you explain the difference ?

[@jwilson3985]

You’re exactly right. This is nothing “new.”

[@mahmoud_elrayes]

Perfect. What is the difference between Carlino and HDR?

[@nileshtawade3788]

Wonderfull ❤

[@MauroCarlino]

HDR is a technique
, Carlino is a manouvre.

[@MauroCarlino]

HDR is applied before introducing the wire into the plaque, allowing for its modulation and facilitating easier wire passage. Carlino is applied when the guidewire stops moving inside the plaque.

[@MauroCarlino]

In short, the difference is that
in HDR contrast comes first,
while Carlino in conventional contemporary CTO PCI wire comes first.
