target vessel revascularization
Repeat intervention on the same coronary vessel previously treated, regardless of location within that vessel.
Full Definition
Target vessel revascularization (TVR) refers to any repeat revascularization procedure (either percutaneous or surgical) performed on the same epicardial coronary vessel that was previously treated, regardless of whether the repeat intervention occurs at the same lesion site or elsewhere in the vessel. TVR is distinguished from target lesion revascularization (TLR), which specifically refers to repeat intervention at the previously treated lesion site. TVR is an important endpoint in cardiovascular research as it reflects both local treatment failure and progression of disease elsewhere in the treated vessel.
Usage
Usage note: Distinguish clearly from target lesion revascularization (TLR) in endpoint definitions.
In Context
- "The 12-month TVR rate was 8.2% in the drug-eluting stent group versus 15.1% in the bare metal stent group." — Clinical trial report
- "TVR included both target lesion revascularization and new lesions in the previously treated vessel." — Endpoint definition
