Filter by:The objective of this study is to evaluate safety and effectiveness of the SINOMED CBC coronary dilatation catheter during PCI in subjects with stenotic coronary arteries.
Peripheral arterial disease (PAD) carries a significant global health burden, and can limit functional capacity and quality of life. Percutaneous transluminal angioplasty (PTA) for PAD is often associated with suboptimal outcomes due to complications following balloon inflation related to vessel trauma and flow limiting dissections that may require bailout stenting. Different strategies and techniques to enhance both acute and longer-term outcomes with drug-coated balloons (DCB) are needed. This is a national, prospective, multi-center, non-randomized, real-world study to evaluate the safety and efficacy of multiple vessel preparation strategies combined with drug-coating balloon (DCB) in Femoropopliteal Artery (F-PA) lesions.
The IVL-Dragon Registry was a multicenter study that enrolled consecutive patients with stent underexpansion treated with IVL in high-volume PCI centers. The primary efficacy endpoint was clinical success, defined as a reduction of stent underexpansion to <30% with no evidence of in-hospital device-oriented composite end point (DOCE) (defined as a composite of cardiac death, target lesion revascularization, and target vessel myocardial infarction).
The objective of this study is to establish reasonable assurance of safety and effectiveness to support an FDA premarket approval (PMA) application for the SeQuent® Please ReX™ Drug Coated PTCA Balloon Catheter as indicated.
The objective of this study is to evaluate safety and effectiveness of the Lacrosse NSE ALPHA coronary dilatation catheter during PCI in subjects with stenotic coronary arteries.
AGENT IDE is a Prospective, Randomized (2:1), Multicenter Trial. The purpose of this study is to assess the safety and effectiveness of the Agent Paclitaxel Coated PTCA Balloon Catheter compared to balloon angioplasty (POBA) in patients with in-stent restenosis (ISR) of a previously treated lesion of up to 26 mm in length (by visual estimate) in a native coronary artery 2.0 mm to 4.0 mm in diameter.
This is a prospective single center, randomized controlled clinical study aimed to compare the clinical and angiographic follow-up results of patients with in-stent restenosis(ISR) after coronary drug eluting stent(DES) implantation treated by fractional flow reserve -guided and angiography guided drug eluting balloon(DEB) intervention. This study intends to confirm the clinical benefits of optimizing DEB intervention of DES-ISR by FFR.
Data regarding the usefulness of percutaneous coronary intervention (PCI) with drug eluting balloon (DEB) vs. thin struts drug eluting stents (thin-DES) for treating in-stent restenosis (ISR) in every day clinical practice is scarce. We aimed to evaluate comparing the efficacy and safety profile of DEB and thin-DES in DES-ISR.
The statistical risk of intrastent stenosis has fallen considerably with the emergence of latest generation coated stents (drug-eluting stents: DES). The number and clinical lifespan of stents implanted over the last twenty-five years, however, explain the fact that restenosis remains a not unusual clinical problem which is expressed as a recurrence of angina or of an acute coronary syndrome (ACS). The mechanisms involved in this restenosis are multifactorial in nature and differ depending on the type of stent and the time since the restenosis occurred. In symptomatic stent restenosis (angina or acute coronary syndrome), a further angioplasty is usually required, occasionally on an emergency basis. Coronary angiography is often not capable of explaining the mechanical causes of this complication. Optical coherence tomography (OCT), a high-resolution endocoronary imaging technique can assist in the understanding of the mechanism of restenosis and guide treatment. OCT during angiography provides a detailed analysis of the stents and potential complications: the presence of neoatherosclerosis with or without plaque rupture, intimal hyperplasia, stent under-deployment, stent fracture and distal or proximal progression of the atherosclerosis. The investigators propose a prospective, multicentre study of all cases of intrastent restenosis, examined by angiography, causing clinical features involving stable angina and acute coronary syndrome. The coronary artery involved will be routinely studied by OCT for a mechanical cause of the intrastent restenosis. The routine use of intrastent OCT may assist in the understanding of causes of restenosis and in the decision on appropriate treatment. There are several possible treatments for restenosis, including balloon angioplasty, coated balloon angioplasty, stenting or aorto-coronary bypass graft surgery.
This is a prospective, multicenter, randomized controlled clinical trial, which plans to enroll 260 subjects.
