NCT05133921
Drug-Coated Balloon (DCB) angioplasty is similar to plain old balloon angioplasty procedurally, but there is an anti-proliferative medication paclitaxel coated on the balloon. Treating in-stent restenosis (ISR) with the DCB has the theoretical advantage of avoiding multiple stent layers and respecting the vessel anatomy. DCB has shown promising results for the treatment of ISR. Currently, DCB has a Class I indication to treat ISR recommended by European Society of Cardiology (ESC) guidelines. In addition, some interventional cardiologist has also applied DCB in de novo lesions in their clinical practice. Although some small sample size RCTs and observational studies have suggested that the clinical prognosis of DCB in primary large vessels is non-inferior to drug-eluting stent (DES), there is no large-scale RCT or cohort studies to compare the clinical effects of DCB and DES. Despite several theoretical benefits of DCB, the procedural-related complications cannot be entirely prevented, such as acute elastic retraction and severe dissection, which would affect coronary blood flow or lead to acute vascular occlusion. Some studies have suggested that optimization of the procedural technique can reduce the occurrence of complications and target lesion failure in the long-term. Proposed criteria include adapting cutting or scoring balloon for pre-dilatation, residual stenosis\<30% post-DCB, maintaining TIMI flow=3, DCB dilation time\<60s, and appropriate balloon to vessel ratio\> 0.91. However, such proposed technique and criteria have not been evaluated in the real-world clinical practice. This current study is designed to investigate the efficacy and safety of DCB in the real world and exploring the optimal procedural configurations.

NCT04826705
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.

NCT06127134
Peripheral arterial disease (PAD) affects more than 200 million people worldwide. Although over 50% are asymptomatic, it accounts for 4% of all amputations. The ischemic limb must be revascularized to help wound healing, reduce the pain of ischemia and preserve the limb's function. So, surgical and percutaneous revascularization choices must be considered in CLI. Classically, CLI revascularization aims to provide at least one patent vessel that delivers in-line flow to the foot. Today, the investigators live in a new era of angioplasty evolving and substituting open vascular surgery, so expanding research on endovascular strategy has been noticed.This confirms the profound impact of angioplasty in vascular surgery as one of the fastest-growing branches of medicine Infrapopliteal artery occlusive disease (IPOD) is a significant cause of critical limb-threatening ischemia (CLTI). The worldwide prevalence of IPOD is between 4.5% and 29%, and most patients live in low-income countries. The angiosomal concept was derived from plastic surgery for the skin flap. This concept delineates the human body into three-dimensional blocks of tissue from the skin to bone and also provides practical application of vascular anatomy for reconstructive surgery. An angiosome is an anatomic unit of tissue consisting of skin, subcutaneous, muscle, and bone fed by a source artery and drained by a specific vein. According to the angiosomal concept, the foot is divided into six distinct angiosomes fed by source arteries, three from the posterior tibial, two from the peroneal, and one from the anterior tibial artery, with functional artery-to-artery connections among muscle, fascia, and skin. Numerous direct inter-arterial connections occur between the foot's main arteries, which provide alternative pathways of blood flow when disruption or compromise affects the arteries that directly feed the angiosome. On the other hand, in patients with CLI, where only one vessel runoff can be established to the foot, direct flow into a patent pedal arch is essential to improve their clinical outcomes. Conventional Endovascular therapy aims to the re-establishment of pulsatile straight-line flow to the lower limb. This results in relieving ischemic pain, healing ulcers, achieving limb salvage, improving quality of life, and potentially prolonging survival. So it became essential to know the differential impact of both concepts on CLI revascularization.
NCT04971356
Drug-Coated Balloon (DCB) angioplasty is similar to plain old balloon angioplasty procedurally, but there is an anti-proliferative medication paclitaxel coated to the balloon. Treating ISR lesions with the DCB has the theoretical advantage of avoiding multiple stent layers and respecting the vessel anatomy. DCB has shown promising results for the treatment of ISR. Currently, DCB has a Class I indication to treat ISR recommended by European Society of Cardiology guidelines. In addition, some interventional cardiologist has also applied DCB in de novo lesions in their clinical practice. Bleeding after PCI remains a substantial clinical problem. Bleeding post-PCI increases the risk of adverse outcomes such as death, non-fatal myocardial infarction, and prolongs hospital stay. Clinical data has suggested that major bleeding post-PCI would increase the risk of mortality 5.7-fold. The antiplatelet medications are the major cause of bleeding events post-PCI. Current guidelines for stents recommended DAPT of aspirin plus a P2Y12 inhibitor for at least 12 months after stent implantation in patients with the acute coronary syndrome. Compared with the DES, because of the absence of metal inside the coronary artery, the use of DCB might theoretically allow shorter duration antiplatelet therapy. However, the optimal course of DAPT for the DCB treated patients remains controversial. In 2013, the consensus from the German group suggested that for the acute coronary syndrome, DAPT should be used for 12 months. The consensus of DAPT developed by the European Society of Cardiology (ESC) in 2017 stated that "in patients treated with DCB, dedicated clinical trials investigating the optimal duration of DAPT are lacking." So far, there are no randomized data showing the optimal DAPT duration for the DCB treated patients. In the current study, we use Aspirin + Ticagrelor for 1-month followed by Ticagrelor monotherapy for 5-month, afterward, Aspirin monotherapy for 6 months to be the antiplatelet regimen in the experimental arm, to compare with the Reference arm, which is Aspirin + Ticagrelor for 12-month in a non-inferiority statistical assumption, aiming to investigate the optimal duration of the DAPT in ACS patients after DCB treatment.

Calcified lesions are very frequent among coronary artery disease stenotic lesions. The prevalence of calcifications ranges from 30 to 40% (by angiography evaluation) but is higher when analyzed by intra coronary imaging. Calcified lesions are very frequent among coronary artery disease stenotic lesions. The prevalence of calcifications ranges from 30 to 40% (by angiography evaluation) but is higher when analyzed by intra coronary imaging. The presence of calcifications increases the risk of adverse evolution after PCI , including stent restenosis, thrombosis and need for repeat revascularisation. Specific and appropriate tools can be used for calcified lesions management , including high pressure non compliant balloons, intravascular lithotripsy and rotablator. Intra vascular OCT has a high sensitivity and specificity for calcium detection among coronary artery lesions. Compared to IVUS, OCT allows a better quantification of calcium sheets (depth extension ) . Several intra coronary imaging based calcified lesions management algorithms have been proposed , but none have been validated in clinical practice.
