angiographic success
Achievement of less than 30% residual stenosis with TIMI 3 flow following percutaneous coronary intervention.
Full Definition
A standardized definition of procedural success in percutaneous coronary intervention based on angiographic criteria. Angiographic success requires achievement of less than 30% residual diameter stenosis in the target lesion combined with restoration of normal (TIMI 3) antegrade flow without major complications. This endpoint serves as an immediate measure of technical success but does not capture clinical outcomes or long-term efficacy. The definition provides consistency across clinical trials and research studies, though modern practice increasingly incorporates additional criteria such as optimal stent expansion confirmed by intravascular imaging.
Usage
