Outcomes of 7560 chronic total occlusion patients undergoing percutaneous coronary intervention: results from a Dutch nationwide registry

Abstract Background The presence of a chronic total coronary occlusion (CTO) is associated with worse clinical outcomes. We aimed to identify CTO patients that are at risk of these outcomes in a nationwide registry. Methods The Netherlands Heart Registration (NHR) is a nationwide registry that registers outcomes of cardiac interventions. For the purpose of this analysis, the data of all patients undergoing PCI from inception of the NHR to December 2019 were selected, that included PCI with at least one CTO in one of the treated coronary arteries. We used multivariate logistic regression of baseline characteristics for the outcome measures target vessel revascularization (TVR)
