Outcome

Type Measure Description Time frame Safety issue
Other Procedural Outcome (Non-Powered): Rate of Stent Expansion MSA achieved in the proximal and distal stented segments relative to their respective reference lumen areas will be assessed. The stent length is divided into 2 equal segments (proximal and distal) except for lesions containing a bifurcation (visually estimated side branch =2.5 mm). When there is a bifurcation present, rather than splitting the stent into two halves, the division is based upon the midpoint of the proximal most side branch.
Acceptable stent expansion (categorical variable): MSA of the proximal segment is =90% of the proximal reference lumen area and the MSA of the distal segment is =90% of the distal reference lumen area.
Unacceptable stent expansion (categorical variable): MSA of the proximal segment is <90% of the proximal reference lumen area, and/or the MSA of the distal segment is <90% of the distal reference lumen area.
Post-PCI stent expansion (%) (continuous variable): The MSA divided by the average of proximal and distal reference lumen areas x 100
Time of PCI Procedure - participants will be followed for the duration of hospital stay, an expected average of 24 hours
Other Procedural Outcome (Non-Powered): Rate of mean stent expansion (%) (continuous variable) The mean stent area (stent volume/analysed stent length) divided by the average of proximal and distal reference lumen areas x 100 will be assessed. Time of PCI Procedure - participants will be followed for the duration of hospital stay, an expected average of 24 hours
Other Procedural Outcome (Non-Powered): Number of participants with Intra-stent plaque protrusion and thrombus A mass attached to the luminal surface or floating within the lumen, meeting the following criteria will be assessed. Protrusion/thrombus is defined as any intraluminal mass protruding at least 0.2 mm within the luminal edge of a stent strut, and will be further classified as Major and Minor:
Major: Protrusion area/Stent area at site of tissue protrusion =10% and the minimal intrastent flow area (MSA - protrusion area) is unacceptable (<90% of respective proximal or distal reference area
Minor: Protrusion area/Stent area at site of tissue protrusion is <10%, or is =10% but the minimal intraluminal flow area (MSA - protrusion area) is acceptable (=90% of respective proximal or distal reference area
Time of PCI Procedure - participants will be followed for the duration of hospital stay, an expected average of 24 hours
Other Procedural Outcome (Non-Powered): Number of participants with Untreated reference segment disease Focal disease with untreated Mean Lumen Area (MLA) <4.5 mm^2 within 5 mm from the proximal and/or distal stent edges will be assessed.

B) Minor (%): any visible edge dissection <60 degrees of the circumference of the vessel and < 3 mm in length
Edge dissections will be further classified as:
i. Intimal (limited to the intima layer, i.e. not extending beyond the internal elastic lamina)
ii. Medial (extending into the media layer)
iii. Adventitial (extending through the external elastic membrane/lamina)
Time of PCI Procedure - participants will be followed for the duration of hospital stay, an expected average of 24 hours

Malapposition will be further classified as:
Major: if associated with unacceptable stent expansion
Minor: if associated with acceptable stent expansion
Stent Malapposition will be tabulated as:
i. Major (%)
ii. Minor (%)
iii. All (Major and Minor) (%)
