Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Complex PCI

All consecutive patients with complex coronary artery disease (CAD) were treated with percutaneous coronary intervention (PCI). The complexity of CAD was defined as having at least one of the following characteristics: chronic total occlusion (CTO), lesion length \>40 mm, severe calcification assessed by angiography or intravascular imaging examination, multivessel PCI during the same intervention, or true bifurcation defined as any lesion involving both the main vessel (MV), proximal or distal and the ostium of the side branch (SB) (Medina 1,1,1; 1,0,1; or 0,1,1).

Intervention Type PROCEDURE

PCI was performed according to the general and local recommendations. The choice of DES among the new generation DES and the decision on procedure optimization belonged to the operator.
