SYNTAX Score Reproducibility and Variability Between Interventional Cardiologists, Core Laboratory Technicians, and Quantitative Coronary Measurements

Abstract

Highly reproducible SYNTAX score measurements were quickly achieved by experienced ACL technicians. In contrast, agreement among ICs after the basic tutorial was initially poor but improved considerably after further training with the ACL, although differences still remained in interpretation of several lesion types. These findings have important implications for adoption of SYNTAX score methodology in routine practice and future clinical trials.
