| Summary: | Objectives To determine patient outcomes in GuideLiner facilitated percutaneous coronary intervention stratified by the SYNTAX score. Design Single centre retrospective cohort analysis. Participants A total of 540 consecutive cases facilitated by GuideLiner at a single center. Main outcome measures Successful stent delivery, in-hospital, 30 day and 1 year mortality rates stratified by SYNTAX score. Results The most common indication for GuideLiner was need for increased support for balloon or stent delivery (82%), 6% for non-coaxial guide, 9% for chronic total occlusion and 3% for selective vessel engagement. Successful stent delivery was achieved in 91% of all cases, with no complications occurred due to GuideLiner use. In-hospital, 30 day and 1 year mortality rates were 2.8%, 2.1% and 4.5%, respectively. The high SYNTAX group was associated with higher rates of initial TIMI score of 0–1; however, the final TIMI score rate of successful delivery and complications did not differ between groups. In-hospital and 1 year mortality rates were higher in the higher SYNTAX groups. Conclusions The GuideLiner is an easy to use guide catheter extension system with high rates of success and low rates of complications, across all SYNTAX groups.
