guidex® versus launcher™ guiding catheter in percutaneous coronary intervention (pci) (guidex_fr)

Conditions: Coronary Artery Disease

Summary: the goal of this clinical trial is to compare two guiding catheters in patients with coronary artery disease during a percutaneous coronary intervention between guidex® guiding catheter (demax) and launcher™ coronary guide catheters (medtronic). the main question\[s\] it aims to answer are: * aren't the safety of medical devices inferior to each other? * aren't the efficacyof medical devices inferior to each other? participants will be randomized (1:1) and have a percutaneous coronary interventionwith one of the two guiding catheters.

cardiovascular disease (cvd) remains the most common cause of death in the european region. in line with the global burden of disease (gbd) estimates from 2001, 43% of all cardio vascular disease (cvd) deaths are related to coronary artery disease (cad). treatment of cad is always based on medication, which may also be supplemented by invasive procedures. the most significant historical advances in the treatment of coronary artery disease were the development of coronary artery bypass grafting (cabg) and percutaneous coronary intervention (pci). an essential element in the success of an angioplasty and in shortening the procedure, the guiding catheter is not simply a support. while, it's primary role is designed to provide a pathway through which balloon dilation catheter, guide wire or other devices are introduced, it can also contribute to significant semantic information since it is the first tool to appear in the field of view. a variety of guiding catheter references are available on the market. guiding catheters of various sizes and shapes are selected based on vessel anatomy, lesion characteristics, vascular access and procedural complexity. the guidex® device is a guiding catheter designed to be used in percutaneous coronary intervention. guidex® device is on the chinese market since september 2015 (certificate renewal in 2020) and is presented for ce marking according to mdr 2017/745. the aim of the study is to assess the essential requirements for ce marking of guidex®: the efficacy and safety of the device. thus the aim of this non-inferiority study is to compare the efficacy and safety for patients with coronary artery disease during a percutaneous coronary intervention between guidex® guiding catheter (demax) and launcher™ coronary guide catheters (medtronic).

Eligibility criteria:
inclusion criteria: * patients need to be at least 18 years old. * patients with significant coronary artery disease who qualify for pci (according to acc/aha/scai 2021 guidelines, including that the patient has received medical therapy with exercise and dietary recommendations before or at the same time as the pci decision and that the clinical decision depends on the cardiology team) and who can be treated with a radial and femoral approach * patients scheduled for for percutaneous coronary intervention and must remain overnight for observation * the target vessel must have a timi flow 3 at baseline * palpable radial or fermoral artery * patients covered by the social security system exclusion criteria: * concomitant use of atherectomy, specialty balloon (intravascular lithotripsy), or investigational coronary devices (intravascular ultrasound, or optical coherence tomography) * active bleeding or significant increased risk of bleeding, severe hepatic insufficiency, current peptic ulceration, proliferative diabetic retinopathy. * prior pci procedure within the last 30 days of the index procedure * current platelet count \<100 x 10\^9cells/l or hgb \<10 g/dl. * uncontrolled severe hypertension (systolic bp \>180 mm hg or diastolic bp \>110 mm hg) * target vessel \< 2.4 mm in diameter * target lesion \> 32 mm in length * patient has allergy to imaging contrast media for which they cannot be pre-medicated * patients with hypersensitivity or contraindication to antiplatelet treatment * patient unable to stop his or her daily oral medication includes metformin treatment during 48 hours. * unstable patient: myocardial infarction, cardiogenic shock or with troponin above the upper limit of the normal laboratory value in the 24 hours prior to the procedure or with elevated troponin and abnormal concomitant ck (non-exhaustive list). * unable to follow the requirements of the protocol. * vulnerable: whose ability or freedom to give or refuse consent is limited. * patients who cannot read or write french; * major protected by law (tutorship, curatorship, safeguarding justice...). * patient is pregnant or nursing
