STrategies of Scheduled Drug-coated Balloons (DCB) Versus Conventional DES for the interveNTional Therapy of de Novo Lesions in Large Coronary vESSels (STENTLESS) Trial

This is a multicenter, open-label, randomized controlled study meant to compare the safety and efficacy of scheduled drug-coated balloon (DCB) and conventional drug-eluting stent (DES) strategy in the treatment of de novo lesions of large coronary vessel with diameter larger than 2.75 mm. The trial was designed to provide high-quality evidence for expanding the clinical indications of DCB, and to explore a better way for coronary intervention based on DCB.

Impact of Procedural Factors on Drug-Coated Balloon Outcomes in Coronary Artery Disease

This registry aimed to investigate drug-coated balloon procedural factors (particularly delivery time and inflation duration) to evaluate the impact on angiographic and clinical outcomes in patients undergoing percutaneous coronary intervention for de novo coronary lesions.

Discontinuation of Antiplatelet Therapy After Drug-Coated Balloon Treatment

The goal of this clinical trial is to evaluate the benefits and risks of discontinuing antiplatelet therapy on clinical outcomes in patients who previously underwent coronary intervention using a drug-coated balloon. The main questions it aims to answer are: Does stopping antiplatelet therapy after 12 months affect the risk of net adverse clinical events? Does stopping antiplatelet therapy reduce the risk of bleeding compared with continuing treatment? Researchers will compare patients who discontinue antiplatelet therapy with patients who continue antiplatelet therapy to determine the impact on clinical outcomes during follow-up. Participants will: Be randomly assigned to either discontinue or continue antiplatelet therapy Receive routine clinical follow-up through clinic visits or telephone contacts Be monitored for cardiovascular events and bleeding outcomes over time

Impact of Drug-coated Balloon Treatment in de Novo Coronary Lesion

This study is the international multicenter registry for drug-coated balloon treatment for de novo coronary lesion.

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.
