TIMI flow grade 1

Associate Editor-In-Chief:

Description
Penetration without perfusion. Contrast material passes beyond the area of obstruction but fails to opacify the entire coronary bed distal to the obstruction for the duration of the cineangiographic filming sequence.

This category is subdivided into:

1.0: dye minimally leaks past the area of obstruction.

TIMI Flow Grade 1 - Left Anterior Descending Artery

1.5: dye leaks well past the area of obstruction but fails to opacify the entire coronary bed.

TIMI Flow Grade 1.5 - Left Anterior Descending Artery

In the case of a TIMI Flow Grade 0, 1, or 1.5 there is no measurable TIMI Frame Count; therefore, DNA (Does Not Apply) is recorded on the case report form in the TIMI Frame Count field.
