Which of the following is NOT a component of Target Vessel Failure (TVF)?

• A. Cardiac death
• B. TVMI
• C. Target vessel revascularization
• D. Procedural success

Answer: (D)

The concept of Target Vessel Failure (TVF) is used to evaluate the long-term success of revascularization procedures such as percutaneous coronary intervention (PCI). TVF generally encompasses events that signify a negative outcome related to the target vessel following treatment. The components typically included in assessing TVF are:

• Cardiac death, which reflects the ultimate consequence in terms of patient mortality derived from issues related to the target vessel.

• Target Vessel Myocardial Infarction (TVMI), which indicates that the target vessel has developed new acute ischemia leading to a heart attack.

• Target vessel revascularization, which involves any surgical or percutaneous intervention performed to alleviate blockages or issues in the original target vessel after the initial procedure.

Procedural success, on the other hand, pertains to the technical outcome of the initial revascularization procedure itself. It does not directly relate to the longer-term outcomes associated with the target vessel's performance post-procedure. Therefore, it is not considered a component of TVF, as TVF focuses on adverse events occurring after the initial success of a procedure, rather than the immediate outcome of the intervention.
