Abstract: Coronary chronic total occlusion(CTO)presents one of the most formidable challenges in percutaneous coronary intervention(PCI).Left ventricular systolic dysfunction(LVSD)is frequently observed in patients undergoing CTO-PCI,who often present with more complex coronary artery lesions and a higher burden of comorbidities,leading to an elevated risk of PCI-related complications.The clinical benefits of revascularization for these patients remain controversial.How to optimize the CTO-PCI strategy and postoperative management to improve patient outcomes represents an urgent issue.This review comprehensively summarizes the clinical characteristics,interventional benefits,interventional strategies,postoperative management,as well as the short-and long-term outcomes for patients with LVSD and CTO,aiming to provide a reference for optimizing the outcome of PCI in this unique and challenging patient subgroup.
