Filter by:Percutaneous coronary intervention (PCI) with drug-eluting stent (DES) implantation has become the dominant treatment strategy for patients with acute and chronic coronary artery disease (CAD) requiring revascularization. Nonetheless, PCI with stent implantation has some limitations and especially patients with severely calcified coronary lesions (approximately 10-20% of all patients with CAD) have an elevated risk for adverse outcomes, including target lesion failure (TLF) and stent thrombosis (ST). Several dedicated PCI devices have been developed for treatment of severely calcified lesions. Whereas especially two of them have shown promising results in smaller, prospective studies. First, the super high-pressure NC PCI balloon (OPN™ NC, SIS Medical AG, Frauenfeld, Switzerland) has been shown to represent an effective and safe device for lesion preparation. Second, the lately introduced Shockwave intravascular lithotripsy (IVL)™ balloon catheter (Shockwave Medical, Santa Clara, CA, USA) appears to be a safe and efficient alternative device for treatment of calcified coronary lesions. However, it remains unknown, if the OPN™ NC balloon is non-inferior to to IVL regarding lesion preparation and completeness of stent expansion in severely calcified lesions.
This is a Prospective randomized controlled study to evaluate the difference of safety，effectiveness between chocolate balloon and plain balloon dilatation in treatment of infrapopliteal artery lesions.
This is a Prospective randomized controlled study to evaluate the difference of safety，effectiveness between endovascular debulking combined drug-coated balloon and balloon dilatation combined stent angioplasty in treatment of femoral-popliteal artery lesions.
In non-acute symptomatic ischemic stroke, the decision-making of medical treatment plus intracranial stenting has been more and more popular, especially in patients with intracranial large severe stenosis or occlusive artery. Nonetheless, there is no evidence from randomized controlled trials evaluating the efficacy of this treatment after the Wingspan Stent System Post Market Surveillance (WEAVE) and Wingspan One Year Vascular Imaging Events and Neurologic Outcomes (WOVEN) trial compared with medical treatment alone. This trial was to investigate whether medical treatment plus intracranial stenting would prevent the recurrent ischemic stroke in the territory of the symptomatic intracranial artery during 1-year follow-up.
The primary goal of the trial is to determine if the experimental arms (rivaroxaban or ticagrelor or both) are superior to the clopidogrel arm for lowering the 1-year rate of ischemic stroke, intracerebral hemorrhage, or vascular death.
The purpose of the SIROOP Registry is to retrospectively and prospectively collect baseline, clinical and procedural characteristics of patients who have undergone PCI and are treated with either currently available sirolimus or paclitaxel coated DCBs (see Table 1), irrespective of clinical presentation as well as to prospectively collect data about their clinical outcomes. Outcomes will be compared in different clinical subgroups. The impact of current DCBs in different clinical settings and coronary artery lesions on cardiovascular outcomes will be assessed.
Coronary artery calcification (CAC) is a common complication of type 2 diabetes mellitus(T2DM), which can significantly increase all-cause mortality and the incidence of serious cardiovascular events, and increase the burden of the national economy. The epidemiological characteristics and the clinical progress of CAC are still not clear. Moreover, the pathogenesis of CAC has not yet been fully elucidated, and lack of specific diagnostic indicators. Arterial calcification is an active, reversible, and multifactorial biological process like bone formation. It is generally believed that early detection of calcification lesions and active targeted treatment may be the key to prevention and treatment of vascular calcification. In addition, statins are commonly used in patients with dyslipidemia and can stabilize CAC plaque. However, the timing, dosage and effect of statins are controversial. Moreover, our previous study found that the expression of miR-32 is significantly elevated in patients with CAC, and can promoting vascular calcification. Herein, this study is to conduct a prospective cohort study on T2DM patients with CAC in Hunan province through a multidisciplinary and multi-center cooperation model, the main research objectives include the following three parts: ① To identify the prevalence, incidence, and characteristics of CAC in T2DM patients in Hunan province, and to build a risk assessment model. ② To observe the effects of statins on the occurrence and development of CAC in patients with T2DM, and to provide clinical data for the improvement of medication guidelines; ③To observe the dynamic changes of serum miR-32 in the progression of CAC in patients with T2DM, and to explore its possibility as a serological diagnosis or prognostic bio-maker of CAC. The completion of this research project is expected to bring a new breakthrough in the field of early diagnosis, prognosis evaluation, and intervention treatment of patients with T2DM combined with CAC, and provide an important reference for the formulation of cardiovascular disease prevention and control strategy.
In this study the investigators retrospectively and prospectively collect information from enrolled subjects undergoing CCTA and evaluate the association of cardiac and non-cardiac imaging with laboratory markers and clinical data including outcome.
This trial is designed to associate angiography-based fractional flow reserve (3D-angio-based FFR) values with optical coherence tomography findings in pre- and post-percutaneous coronary intervention in patients with non-ST segment elevation acute coronary syndromes.
This prospective, multicenter, randomized, controlled, open-label clinical study has a target enrollment of 240 subjects. It will explore whether STEMI patients transferred to a PCI center following thrombolytic therapy and expected to have stent implantation might benefit from an alternative treatment strategy and the use of new technologies designed to improve myocardial protection throughout the medical care process.
