Rationale and design of the RECording COurses of vasculaR Diseases registry (RECCORD registry).

BACKGROUND: The prevalence of peripheral artery disease (PAD) is increasing worldwide. Revascularization procedures constitute a cornerstone of the therapy in PAD, not only in critical limb ischaemia but increasingly also in patients with intermittent claudication. The German Society of Angiology - Society for Vascular Medicine is establishing a nationwide, prospective, multicentre registry to address the lack of contemporary real life data regarding current practice of medical and interventional care in vascular patients and its subsequent long-term outcome. PATIENTS AND METHODS: The RECording COurses of vasculaR Diseases registry (RECCORD registry) is an observational, prospective, multicentre, all-comers registry platform. In the initial phase, patients referred for endovascular revascularization of PAD of the lower limbs will be prospectively included and followed up for at least one year. At baseline, data on patients' demographic characteristics, comorbidities, previous peripheral interventions, medication, and clinical stage of PAD (Rutherford category), haemodynamic parameters, and procedural data including complications will be assessed. Major adverse cardiac and limb events will be recorded at planned (at six and 12 months) and at any unplanned visits. The therapeutic management will be exclusively left to the discretion of the vascular specialists. RESULTS AND CONCLUSIONS: The RECCORD registry will provide a comprehensive dataset depicting the current real life practice and outcome of vascular care. The seven predefined quality indicators will be used for benchmarking the participating centres. Moreover, identifying factors promoting a favourable outcome might pave the way for an evidence-based therapeutic strategy and a dedicated therapeutic pathway for patients with PAD including patient-oriented best interventional approaches. In the future, the RECCORD registry may provide a general platform to study the courses of various defined vascular diseases in order to get detailed insights into the real life current practice of health care provided to vascular patients.

Multiple Stent Delivery System "Multi-LOC": Focal self-expanding nitinol stenting of complex femoropopliteal lesions-A monocenter feasibility pilot study.

AIMS: The Multiple Stent Delivery System (VascuFlex® Multi-LOC) is a novel stent delivery system with six short stents (13 mm long each) mounted on one wire-guided catheter, designed for the treatment of femoropopliteal arteries. The aim of the present study is to evaluate the safety and the feasibility of the VascuFlex® "Multi-LOC" stent delivery system, which enables spot stenting without changing the delivery system. METHODS AND RESULTS: After proof of concept in a porcine model and after European Conformity marking, first clinical experiences were gathered in 20 patients with severe intermittent claudication or critical limb ischemia. First-in-human data are presented. The study included 20 limbs that underwent femoropopliteal revascularization for claudication (n = 14) or critical limb ischemia (n = 6). "Multi-LOC" provisional spot stenting resulted in acute technical success in all lesions with resolution of flow-limiting dissection and elastic recoil after balloon dilatation of the femoropopliteal artery. There were no device-related complications. Follow-up examinations after 30 to 40 days revealed no major adverse events, and six months' results were encouraging. CONCLUSIONS: First clinical use of the novel Multiple Stent Delivery System (Multi-LOC) after balloon dilatation of the femoropopliteal artery was safe and feasible in this early study.
