Percutaneous coronary intervention of unprotected left main stenoses – Procedural data and outcome depending on SYNTAX I Score

摘要

BackgroundWe hypothesized that SYNTAX I score is a predictor for procedure complexity in left main PCI. Procedure complexity, duration and contrast load may contribute to adverse outcome of complex left main percutaneous coronary intervention (PCI). MethodsIn 105 consecutive patients who underwent PCI of unprotected left main coronary artery stenoses between 2014 and 2016, clinical parameters as well as PCI characteristics and follow-up data were analyzed. ResultsThe mean SYNTAX I score was 29?±?12, with 66 patients having a SYNTAX I score?≤?32 and 39 patients a SYNTAX I score?>?32. In patients with high SYNTAX I score vs. low-to-intermediate SYNTAX I score, single stent techniques were performed significantly less frequently (18% vs. 68%;p?
