Type 5 Periprocedural (post-SAVR, TAVR or CABG) MI (48 h after the index procedure)
In patients with normal baseline CK-MB: The peak CK-MB measured within 48 h of the procedure ≥10 the local laboratory ULN or CKMB ≥5 ULN with one or more of the following:

• New pathologic Q-waves in ≥2 contiguous leads
• New persistent LBBBc
• Flow-limiting angiographic complications in a major epicardial vessel or >1.5 mm diameter branch
• Substantial new loss of viable myocardium on imaging related to the procedure

In the absence of CK-MB measurements and a normal baseline cTn, a cTn (I or T) level measured within 48 h of the procedure rises to ≥70 the local laboratory ULN or ≥35 ULN with one or more of the following:

• New pathologic Q-waves in ≥2 contiguous leads
• New persistent LBBBc
• Flow-limiting angiographic complications in a major epicardial vessel or >1.5 mm diameter branch
• Substantial new loss of viable myocardium on imaging related to the procedure
• In patients with elevated baseline CK-MB (or cTn): The CK-MB (or cTn) rises by an absolute increment equal to those levels recommended above from the most recent pre-procedure level plus new ECG changes as described.
