an Observational Study Evaluting the Effectiveness and Safety of DKutting LL Noval Scoring Balloon Angioplasty for Vessel Preparation Facilitated by IVUS on the Lower Limb Ischemia Patients With Calcified Lesions

This is a prospective, single-center, single-arm, observational study. It plans to enroll 58 patients with moderate to severely calcified lesions in the femoropopliteal or infrapopliteal arteries. Participants will be treated with the Scoring Balloon Dilatation Catheter manufactured by DK Medtech (Suzhou) Co., Ltd. The study aims to evaluate the immediate technical success rate and the improvement in lumen area and calcification burden as assessed by IVUS following percutaneous transluminal angioplasty with the scoring balloon. Clinical follow-ups will be conducted at discharge (or within 7 days), 1 month, 3 months, and 6 months post-procedure to observe secondary endpoints including the incidence of clinically driven target lesion revascularization and changes in Rutherford classification

Safety and Effectiveness Evaluation of iCover Covered Stent for the Treatment of the Aorto-iliac Occlusive Disease

The objective of this prospective, multi-center, non-randomized, single-arm observational study is to evaluate the safety and the efficacy of the iCover covered stent over a 24-month follow-up period for the treatment of de novo iliac occlusive lesions, defined by a significant vessel stenosis ≥70%, in patients with symptomatic arteriopathy of the lower limbs (Rutherford class 2 to 5).

Observatory on the Use of the Shockwave Medical C2 Coronary Lithotripsy System in the General Population in France.

Coronary calcified lesions will have an increasing impact in the daily practice of coronary angioplasty, considering the epidemiological explosion of factors favoring coronary calcifications, first of all diabetes. Moreover, calcified lesions are underestimated in angiography and associated with an increase in angiographic complications, as well as with a worse clinical prognosis. The usual techniques for the preparation of calcified plaque, in particular rotary atherectomy, have a low penetration rate in France (3% of procedures) and are associated with an increase in per-procedural complications without clinical evidence of effectiveness4. A new device has been developed by Schockwave Medical Inc. for the treatment of calcified lesions to facilitate stent delivery: the C2 Shockwave Medical® Coronary Lithotripsy System (IVL), Inc. This system uses the principle of lithotripsy to induce microfractures in the calcified plaque prior to low-pressure balloon dilatation. The objective of the study is to evaluate the safety and performance of the C2 Shockwave Medical® (IVL), Inc. coronary lithotripsy system in coronary angioplasty in the general population in France.

A Study of Endovascular Treatment of Femoropopliteal Arterial Occlusive Lesion With Drug-Coated Balloon

There have been a number of randomized controlled studies (RCT) showing the efficacy of the endovascular treatment with drug-coated balloons (DCB) in the femoropopliteal artery lesions. However, these studies have been carefully designed, and most of them have excluded long-length lesions and severely calcified lesions. In addition to being used alone in the real word, drug-coated balloons (DCB) are also used in combination with stents or debulking devices, but in these randomized controlled studies (RCT) they are only compared with standard percutaneous transluminal angioplasty (PTA). Therefore, the investigators initiated this study, which is a prospective, multicenter, observational real-world study of short and long-term outcome in endovascular treatment of femoropopliteal arterial occlusive lesions with DCB.

France PCI Registry : National Observatory of Interventional Cardiology

Rigorous clinical practice assessment is a key factor to improve patient's care and prognosis in interventional cardiology (IC). A multicentric IC observational study (CRAC), fully integrated to usual coronary activity report software, started in Centre Val de Loire (CVL) region in 2014. CRAC observatory was conduced on five IC CathLab of CVL region. Quality of collected data is regularly evaluated and allowed building an exhaustive, and reliable database. This solution could easily be developed in other French regions.

European All-comers' Multicentric Prospective REGISTRY on LUMINOR© Drug Eluting Balloon in the Superficial Femoral Artery and Popliteal Artery With 5 Years Follow-up.

The objective of this all-comers registry is to explore the safety, efficacy, and cost-efficiency of the LUMINOR© DEB in de-novo and restenotic-FP lesions. For de-novo and restenotic lesions, especially for calcified and/or long lesions/occlusions, the use of debulking devices to improve recalibration and drug penetration will be evaluated in a specific sub-group.
