Complex CAD Treated With PCI With DES Implantation.

COMPLEX Registry is an investigator-initiated, retrospective, high-volume Polish single-center clinical registry enrolling 980 consecutive patients with complex coronary artery lesions treated percutaneously between September 2015 and December 2021. All data were collected prospectively as regards the clinical and technical endpoints. The study aimed to assess the safety and efficacy of new-generation, thin-struts DES in patients with complex CAD at long-term clinical follow-up. The primary endpoint of the study was the occurrence of TLR during follow-up. Secondary endpoints were a procedural success and the occurrence of MACE, including all-cause death, MI, or TLR.
