TIMI flow
Also written as: TIMI — Thrombolysis in Myocardial Infarction
Standardized grading system (0-3) for assessing blood flow through coronary arteries during angiography.
Full Definition
The Thrombolysis in Myocardial Infarction (TIMI) flow grade is a standardized classification system used to describe the degree of coronary blood flow during cardiac catheterization. TIMI 0 indicates no flow, TIMI 1 shows minimal flow, TIMI 2 demonstrates partial flow, and TIMI 3 represents normal flow. This grading system is essential for assessing the success of interventional procedures and predicting patient outcomes.
Usage
Usage note: Always specify the numeric grade (0-3) when documenting TIMI flow.
In Context
- "The report documented TIMI 3 flow in all coronary vessels following successful percutaneous intervention." — Cardiac catheterization report
- "Pre-intervention imaging showed TIMI 0 flow in the left anterior descending artery." — Clinical case study
