Abstract: Background: Patients with severe coronary artery disease with a clinical indication for revascularisation but who are at high procedural risk are potentially underserved and understudied. Advances in current percutaneous coronary intervention (PCI) techniques and technology, in addition to appropriate patient selection may help treat such patients. The relative frequency and outcomes following PCI in these high-risk patients are not well known. Objective: We report the early and long-term mortality of PCI for patients undergoing complex high-risk indicated procedures (CHIP). Methods: Patients from the Melbourne Interventional Group registry between 2005 and 2018 undergoing CHIP were compared to non-CHIP. CHIP was defined as those with a left ventricular ejection fraction <30%, having one anatomical feature such as left main coronary artery PCI, American College of Cardiology (ACC)/American Heart Association (AHA) B2/C lesion, multivessel disease, or chronic total occlusion in addition to three or more of chronic obstructive pulmonary disorder, diabetes, kidney failure, age ≥75, and peripheral vascular disease. Long-term mortality was obtained by National Death Index linkage. Results: 20,973 procedures were included. Conclusion: In this multicentre registry, the proportion of patients undergoing CHIP is very low. Despite good procedural success and reasonable in-hospital outcomes, long-term mortality is poor. Further research into patient selection and the benefits of CHIP compared to those treated medically should be considered.
