Popis: Introduction: The use of mechanical circulatory support (MCS) in complex percutaneous coronary intervention (PCI) is the subject of ongoing investigation, but the role of MCS in chronic total occlusion (CTO) PCI is not well studied. Methods: We analyzed the patient and angiographic characteristics and procedural outcomes of 7,171 CTO PCIs performed between 2012 and June 2021 at 35 international centers. Results: Mean patient age was 64.5±10 years, mean left ventricular ejection fraction was 50 ± 13 % and 82% were men. MCS was used in 4.5% of the overall cases, MCS use was elective in 78.7% and urgent in 21.3%. The most common type of MCS was Impella CP (55.5%) followed by intra-aortic balloon pump (14.8%), Tandem Heart (10.0%) and Impella 2.5 (8.7%). Diabetes mellitus (51.0% vs. 42.4%, p=0.003), prior congestive heart failure (60.6% vs. 27.9%, p Conclusions: In a contemporary, multicenter registry MCS was used in 4.5% of CTO PCI. Cases where MCS was used were associated with lower technical and procedural success with higher periprocedural major complication rates. Further investigation is required to see if elective use of MCS can improve outcomes in patients with increased comorbidities and higher lesion complexity.
