Optical Coherence Tomography - Guided Protocol for Left Main Percutaneous Coronary Intervention

The first OCT run (run1) analyse plaque characteristics, identify proximal and distal landing zones (according to previously published criteria) , measure lesion length and reference segments dimensions (diameters and luminal areas). The second run (run2) aims to assess adequate guidewire recrossing point into stent jailed side branch and identify early stent mechanical non-optimal results. The third run (run3) analyse final stent expansion and identify major struts malposition and edge dissection.
