Rajaie Cardiovascular Medical and Research Center‑Percutaneous Coronary Intervention Registry: A Real‑World Registry on Coronary Interventions in a Tertiary Teaching Cardiovascular Center

Introduction: Clinical registries are a targeted way of data collection aimed at finding a solution to a specific clinical inquiry. The present report introduces the Rajaie Cardiovascular, Medical and Research Center percutaneous coronary intervention (RHC‑PCI) Registry. The primary objectives of the RHC‑PCI Registry consist of monitoring different complex PCI procedures and their mutual impact on interventional cardiology programs. Methods: RHC is a large and well‑known cardiovascular tertiary center in Iran. The RHC‑PCI Registry was first launched in 2015, since which time it has collected >5000 parameters regarding the baseline, clinical, and procedural characteristics of various PCI procedures. Noncomplex coronary interventions, bifurcation stenting, left main interventions, chronic total occlusion (CTO) PCI, and bypass graft interventions comprise the major categories gathered by the RHC‑PCI Registry. The main registry outcomes are comprised in‑hospital mortality, major adverse cardiovascular events, vascular access site complications, and 6‑month all‑cause mortality. Results: In this primary report, we elaborate on the principal infrastructure of the RHC‑PCI Registry and present a synopsis of the registry scope. During the first 40 months of the registry, 11,005 patients underwent PCI. The acute coronary syndrome was reported in 5043 (45.8%) patients. Bifurcation stenting, left main interventions, CTO PCI, and bypass graft interventions were performed in 1679 (15.2%), 236 (2.1%), 946 (8.5%), and 764 (6.9%) patients, respectively. The preferred access site was the femoral artery (n = 6614, 60%), and drug‑eluting stents were deployed in 9230 (83.8%) patients. In‑hospital mortality in the total registry data was reported in 104 (0.9%) patients. Conclusions: This report introduces the RHC‑PCI Registry, its primary objectives, infrastructure, and preliminary results (the 3‑year outcome).
