Demographic and procedural characteristics in the RECording COurses of vasculaR Diseases (RECCORD) registry - the first 1000 patients

Background: The RECcordirg COurses of vasculaR Diseases (RECCORD) registry established by the German Society of Argiology - Society for Vascular Medicine aimed to address the lack in contemporary real-world data regarding current practice of medical and interventional care in vascular patients. We herein report the demographic and procedural characteristics of the first 1000 patients undergoing erdovascular revascularization (EVR) for symptomatic peripheral artery disease (PAD). Patients and methods: RECCORD is an observational, prospective, multicenter, all-corners registry. Only patients undergoing EVR for symptomatic PAD are included and followed up for at least 1 year. Demographic characteristics, comorbidities, previous peripheral vascular interventions, medication, clinical stage of lower extremity artery disease (Rutherford category), hemodynamic parameters, and procedural data including complications are recorded via an entirely web-based platform. Results: Of the first 1000 patients (mean age 70 +/- 10 years, 35% female) with 1096 EVR at 1477 vascular segments of the lower extremities, 25.0% were at the stage of chronic limb threatening ischemia (CLTI) and 75.0% at non-CLTI. The femoropopliteal segment was the dominant target lesion site (61.0%), followed by iliac (26.4%) and below-the-knee EVR (10.3%). Only angioplasty was performed in 130 EVR (11.9%), adjunctive drug coated balloons (DCB) in 498 (45.4%), additional stenting in 633 (57.8%). Debulking devices were used in 106 (9.7%) EVR. Clinical (Rutherford categories) and hemodynamic parameters (ankle brachial index) as well as secondary preventive medication were significantly improved post EVR. Periprocedural complications occurred in 63 (5.7%) EVR with pseudoareurysm as the leading complication type in 26 (2.4%) EVR. Conclusions: The baseline data of the first 1000 patients from the RECCORD registry representing the real-world setting illustrate that the majority of EVR are performed in patients with claudication. Adjunctive use of DCB and stentirg are the dominant types of EVR, while periprocedural complications are at an acceptable low rate.
