angiographic success
Achievement of less than 20% residual stenosis with normal flow following interventional treatment.
Full Definition
Angiographic success is a standardized endpoint used in interventional cardiology to define procedural success based on imaging criteria. It is typically defined as achieving less than 20% residual stenosis in the treated vessel with restoration of normal antegrade flow (TIMI 3 flow). This metric provides an objective measure of immediate procedural outcome and is widely used in clinical trials, quality assurance programs, and procedural documentation. While angiographic success is important, it should be distinguished from clinical success, which also considers the absence of major adverse events and symptom relief.
Usage
Usage note: Always specify the residual stenosis percentage and final TIMI flow grade.
