TIMI flow
Pronunciation: TY-mee flow
A standardized grading system for assessing coronary blood flow during angiography.
Full Definition
The Thrombolysis in Myocardial Infarction flow grade, a standardized classification system ranging from 0 (no flow) to 3 (normal flow) used to assess the degree of coronary perfusion. TIMI 0 indicates complete occlusion, TIMI 1 shows penetration without perfusion, TIMI 2 demonstrates partial perfusion with delayed clearance, and TIMI 3 represents normal flow and clearance. This classification is essential for evaluating procedural success and clinical outcomes in interventional cardiology.
Usage
Usage note: Always capitalize TIMI. Include numerical grade when reporting (TIMI 3 flow, not TIMI flow).
In Context
- "Post-intervention angiography demonstrated restoration of TIMI 3 flow in the left anterior descending artery." — Catheter laboratory report
- "The patient presented with TIMI 0 flow in the right coronary artery requiring primary PCI." — Emergency consultation note
