Patient outcomes in GuideLiner facilitated percutaneous coronary intervention stratified by the SYNTAX score: A retrospective analysis

Abstract

ObjectivesTo determine patient outcomes in GuideLiner facilitated percutaneous coronary intervention stratified by the SYNTAX score.DesignSingle centre retrospective cohort analysis.ParticipantsA total of 540 consecutive cases facilitated by GuideLiner at a single center.Main outcome measuresSuccessful stent delivery, in-hospital, 30 day and 1 year mortality rates stratified by SYNTAX score.ResultsThe 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.ConclusionsThe GuideLiner is an easy to use guide catheter extension system with high rates of success and low rates of complications, across all SYNTAX groups.

The Association Between SYNTAX Score and Long-term Outcomes in Patients With Unstable Angina Pectoris: a Single-center Retrospective Study

“…Moreover, although coronary revascularization can improve the prognosis of medium and high risk patients with unstable angina pectoris (UAP) in early studies [3][4][5][6][7] , most risk scoring systems, such as GRACE and TIMI score, include clinical indicators, not considering characteristic of coronary artery disease. Using SYNTAX score to assess differences in long-term outcomes between medical therapy and PCI have seldom been found.…”
