The utility of guide catheter extensions (GCE) in coronary interventions and specifically chronic total occlusion (CTO) interventions.

Abstract

Key points Guide catheter extensions (GCE) are associated with improved success in chronic total occlusions interventions. GCE can be associated with a higher risk of complications, although found to not be statistically significant in this large multicenter registry. Care must be exercised in the use of GCE to ensure a successful intervention and limit rates of complications.
