target vessel revascularization
Repeat intervention on the same coronary artery previously treated during index procedure.
Full Definition
Target vessel revascularization (TVR) refers to any repeat revascularization procedure performed on the same coronary artery that was treated during the index intervention. This includes both target lesion revascularization (repeat treatment of the exact same lesion) and treatment of different lesions within the same vessel. TVR is an important endpoint in clinical trials and quality assessments of percutaneous coronary interventions, as it indicates either restenosis of the treated lesion or progression of disease elsewhere in the target vessel.
Usage
Usage note: Distinguish from TLR (target lesion revascularization) which is more specific.
In Context
- "The patient required target vessel revascularization due to in-stent restenosis at 8 months." — Follow-up cardiology note
- "The 12-month TVR rate was 4.2% in the drug-eluting stent group." — Clinical trial report
