target vessel revascularization
Also written as: TVR — target vessel revascularization
Any repeat coronary intervention involving the initially treated vessel, regardless of the specific lesion location.
Full Definition
A clinical endpoint used in interventional cardiology studies to assess the need for repeat procedures on previously treated coronary vessels. Target vessel revascularization includes both target lesion revascularization and new interventions elsewhere in the same vessel. This metric is considered a broader measure of procedural success than target lesion revascularization alone. It encompasses scenarios where restenosis occurs adjacent to the original treatment site or where disease progression affects other segments of the same coronary artery.
Usage
Usage note: Often abbreviated as TVR in clinical contexts; distinguish from TLR in endpoint definitions.
