TIMI flow
Pronunciation: TIE-mee
Also written as: TIMI — Thrombolysis In Myocardial Infarction
A standardized grading system (0-3) used to assess coronary blood flow during angiography.
Full Definition
TIMI flow refers to the Thrombolysis In Myocardial Infarction flow grade, a visual assessment tool used during coronary angiography to evaluate the degree of coronary perfusion. The scale ranges from TIMI 0 (no flow) to TIMI 3 (normal flow), with TIMI 1 representing penetration without perfusion and TIMI 2 indicating partial perfusion. This classification system is crucial for assessing procedural success and patient outcomes.
Usage
Usage note: Always capitalize TIMI when referring to the flow grade system.
In Context
- "Post-intervention angiography demonstrated TIMI 3 flow in the previously occluded vessel." — Catheterization report
