Definite Treatment Failure:

Definite Stent Thrombosis:

TF-1

Definite Stent Thrombosis proven at angiography or at autopsy as defined by ARC

ST-1

Definite Stent Thrombosis proven at angiography or at autopsy as defined by ARC

TLR (either PCI or CABG because of re-stenosis in the initial treated lesion)

Angiographically proven re-stenosis even if it left untreated

Cardiac death definitely connected to the initial PCI

Probable Treatment Failure:

Probable Stent Thrombosis:

TF-2

Any unexplained death within the first 30 days of initial PCI

ST-2

Any unexplained death within the first 30 days of initial PCI

Cardiac death within 30 days with the exception of events classified in TF-7

TF-3

Any MI that is related to the initially treated vessel

ST-3

Any MI that is related to the initially treated vessel

Possible Treatment Failure:

Possible Stent Thrombosis:

TF-4

Any unexplained death later than 30 days after the initial PCI

ST-4

Any unexplained death later than 30 days after the initial PCI

Cardiac death later than days 30 after the initial PCI with the exception of events classified in TF-7

TF-5

Acute MI with uncertain/indeterminable localization

ST-5

Acute MI with uncertain/indeterminable localization (our new addition)

TF-6

TVR outside the initially treated lesion

Stenosis in the initially treated vessel outside the initially treated segment even if it is left untreated

Rejected Treatment Failure:

Rejected Stent Thrombosis (our new addition):

TF-7

A MACE but with death unconnected to the initial PCI treatment

ST-7

A MACE but with either death unconnected to the initial PCI treatment

A MACE but with MI outside initial treated vessel territory

MI outside initial treated vessel territory

A MACE but with Deaths from other reasons

Deaths from other reasons

Revascularization outside initially treated vessel

Significant stenoses outside initially treated vessel left untreated

An event unrelated to the initial PCI
