Abstract
OBJECTIVES: There are limited data on the association of operator volume with the outcomes of chronic total occlusion (CTO) percutaneous coronary intervention (PCI).
METHODS: We analyzed the association between operator volume and procedural outcomes of 7035 CTO-PCIs performed between 2012 and February 2021 at 30 centers.
RESULTS: The study population was divided into 3 groups based on annual operator CTO-PCI volume: low-volume operators (LVO:/year; 39.7% of the cases); medium-volume operators (MVO: 30-60 cases/year; 25.7% of the cases); and high-volume operators (HVO: >60 cases/ year; 34.6% of the cases). Mean patient age was 64.4 ± 10 years and 82% were men. Cases performed by HVOs were more complex, with higher J-CTO score compared with cases performed by MVOs and LVOs (2.72 ± 1.27 vs 2.39 ± 1.19 vs 2.12 ± 1.27, respectively; P
CONCLUSIONS: In a contemporary, multicenter registry, 40% of CTO-PCI cases are performed by LVOs performingsuccess, but also higher periprocedural major complication rates, potentially due to higher lesion complexity.
