Pre-PCI Lesion Assessment

Prior to stent implantation OCT can provide quick and accurate measurements of the minimal luminal area (MLA), distal and proximal reference areas, diameters and lesion length. OCT can be used to determine landing zones to estimate the optimal stent length.

There are two types of pullback modes: the 75 mm Survey Mode and the 54 mm High Resolution Mode:

  • The 75 mm Survey Mode – fast and efficient and utilizes minimal contrast.
  • The 54 mm High Resolution Mode – has twice the frame density producing a relatively sharper image.
