Case 7
Case 7a:
* 3 or more vessel reference diameters
Case 7b:
* less than 3 vessel reference diameters
NB: Serial stenoses which are less than 3 reference vessel diameters apart, should be scored as one lesion. Stenoses at a greater distance from each other (more than 3 reference vessel diameters), are considered as separate lesions.
Case 7a should be described in the SYNTAX score as two lesions:
1) one lesion involving segments: 5, 6 and 11 (lesion characteristic: ‘true bifurcation’ class 1,1,1) and
2) one lesion involving segment 6.
Case 7b should be described in the SYNTAX score as one lesion: 1) one lesion involving segments: 5, 6 and 11 (lesion characteristic: ‘true bifurcation’ class 1,1,1)
* 3 or more vessel reference diameters
Case 7b:
* less than 3 vessel reference diameters
NB: Serial stenoses which are less than 3 reference vessel diameters apart, should be scored as one lesion. Stenoses at a greater distance from each other (more than 3 reference vessel diameters), are considered as separate lesions.
