Active clinical trials for "Coronary Artery Disease"

The purpose of this study is to assess if using the Impella® CP (or Impella® 2.5) device during high-risk PCI in patients with reduced left-sided heart function will result in an improvement in symptoms, heart function and health after a heart procedure compared to the current standard of care.

The purpose of the DYNAMITE trial (Dynamic CT stress myocardial perfusion, CT fractional flow reserve (FFR-CT) and coronary CT angiography for optimized treatment strategy in patients with chest pain syndromes) is to determine the ability of combined anatomical and functional cardiac CT imaging to improve morbidity and mortality in patients with suspected or known ischemic heart disease.

This study consisted of a randomized controlled trial group and a long balloon observation group. In the randomized control group, 280 subjects with in-stent restenosis were planned to be recruited and randomly assigned to the test group and the control group in a 1:1 ratio; 30 consecutive subjects will be enrolled in the long balloon observation group, using graceful molimus release coronary balloon catheter with length of 45mm; All 310 subjects were followed up at baseline, surgery, discharge, 1 month after surgery, 6 months after surgery, 9 months after surgery, 1, 2 and 3 years after surgery, and angiography was performed at 9 months after surgery.

The study aims to evaluate a modified antiplatelet therapy associated with Firehawk low-dose rapamycin DES in acute myocardial infarction patients treated with complete revascularization strategy. The modified antiplatelet therapy consists of a reduced duration of Dual Antiplatelet Therapy post procedure (ie. 1 month duration) followed by P2Y12 inhibitor monotherapy for the next 11 months. It is hypothesized that in the setting of clinically stable, low to moderate complexity acute Myocardial Infarction patients, a modern approach combining a stent with high biocompatibility feature, complete revascularization strategy and modified antiplatelet therapy may be associated with similar outcomes, or even a significant benefit compared with guidelines-recommended 12-month DAPT. This benefit could be driven by a reduced risk in significant bleeding events, while keeping a comparable protection against ischemic risk. Enrolled subjects will be randomized in a 1:1 ratio to either cessation of aspirin at 1 months, either continuation of DAPT. Selection of the P2Y12 inhibitor agent is left to investigator judgment but has to be in line with the current ESC guidelines. Subjects treated with the Firehawk or Firehawk Liberty coronary stent will be included in this study.

This study compares a new method of treating severely calcified coronary lesions, the intracoronary lithoplasty, with the current gold standard, the rotablation.

The optimal treatment of coronary bifurcation lesions is complex and remains subject of current research. There is ongoing debate about the optimal strategy for bifurcations with upfront two-stent strategy or provisional one-stent strategy. Current European Society of Cardiology (ESC) guidelines advise a provisional approach with optional bailout two-stent strategy in case of suboptimal result of the side branch (SB). However, a two-stent strategy (either upfront and bailout) caries technical difficulties and is associated with increased procedure duration and costs and higher exposure of the patient to radiation and contrast. Therefore there is upcoming interest in the use of a drug-eluting balloon (DEB) in the side branch of bifurcation lesions after provisional approach. Drug-eluting balloons are conventional semi-compliant angioplasty balloons covered with an anti-proliferating drug, which is released into the vessel wall during inflation. Several small pilot studies have successfully investigated a hybrid approach with use of DEB in addition to the provisional strategy. This hybrid approach has shown to be safe and feasible, however no large trials have been performed comparing this with current two-stent bifurcation strategies. The aim of this randomized controlled, single blinded, multicenter trial is to investigate whether a hybrid DEB approach is non-inferior to a conventional two-stent strategy in patients with de novo bifurcation lesions and a suboptimal result of the SB after provisional approach. Patients included in this study will receive PCI using provisional approach (implantation of drug-eluting stent (DES) in the main branch). Patients with an unsatisfactory result of the SB after provisional PCI (≥ 70% residual stenosis and/or diminished flow < Thrombolysis in Myocardial Infarction (TIMI) III) will be randomized in a 1:1 ratio to receive the Hybrid DEB approach or the two-stent strategy. Patients with a satisfactory result of the side branch after provisional PCI will be included in a registry. Follow-up will be performed at 12 months and at the anticipated median 2 year follow-up with a minimum follow-up of 1 year in each subject by either a phone call or outpatient clinic visit. During follow-up information regarding cardiovascular drug use, hospitalizations, invasive and non-invasive diagnostic tests, angina status and SAE's is obtained.

Diabetes mellitus is one of the most important diseases worldwide. Patients with diabetes mellitus, as compared to those without, present a more diffuse, progressive coronary artery disease with smaller lumen dimensions leading to suboptimal outcomes after PCI and increased risk of restenosis and adverse cardiac events. Lesion pre-dilation prior to DES implantation is a crucial procedural step as it creates microdissections, which are required for optimal uptake of the drug. However, the best pre-dilation strategy has not yet been determined. Therefore, the aim of this study is to evaluate a strategy based on pre-dilation with cutting balloon (CB) followed by Abluminus Sirolimus-eluting stent (ASES) implantation for de novo coronary lesions in patients at high risk of restenosis.

This study is a prospective, open-label, two-arm, randomized multicenter trial to identify whether immediate multi-vessel PCI would be better in clinical outcomes compared with culprit lesion-only PCI for AMI and multi-vessel disease with an advanced form of CS patients who require veno-arterial extracorporeal membrane oxygenator (VA-ECMO).

The goal of this clinical trial is to compare the crossability of novel spherical tip versus regular noncompliant balloon in CHD population with tortuous coronary artery leisions that requiring postdilation after stent implantation. The main question it aims to answer is: •Wether the spherical tip balloon have advantages in terms of crossability compared to regular noncompliant balloons Participants will sign an informed consent form, collaborate with data collection, and accept the intervention measures from corresponding groups. Researchers will compare spherical tip balloon with regular noncompliant balloon to see if there is any difference in crossability.

This prospective, multicenter, non-randomized, single arm, objective performance goal (OPG) study is designed to evaluate clinical outcomes after complete revascularization by PCI and imaging guidance (OCT) in patients with multivessel coronary artery disease including left anterior descending (LAD) presenting with stable angina, or documented silent ischemia, or non-ST segment elevation acute coronary syndrome (NSTE-ACS).
