Orbital Atherectomy vs. Angioplasty for Coronary Artery Disease
(ECLIPSE Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial compares two methods for treating severely blocked heart arteries: orbital atherectomy and conventional balloon angioplasty. Orbital atherectomy uses a special tool to shave away hard plaque in arteries, while balloon angioplasty uses a balloon to open them. Researchers aim to determine which method is superior before placing a drug-eluting stent, which releases medication to keep the artery open longer. Individuals with stable or recently worsened heart disease who haven't had recent unsuccessful heart procedures might be suitable for this trial. As an unphased trial, this study provides a unique opportunity to contribute to understanding which treatment method may be more effective for future patients.
Do I have to stop taking my current medications for the trial?
The trial information does not specify if you need to stop taking your current medications. However, it mentions that participants should not have a contraindication to certain therapies, so it's best to discuss your medications with the trial team.
What prior data suggests that these techniques are safe for treating coronary artery disease?
Research has shown that the Orbital Atherectomy System (OAS), also known as the Diamondback 360, has been tested for safety and effectiveness. One study found that 19.4% of patients experienced major heart-related issues, such as heart attacks or the need for another procedure, within two years after treatment. These results are typical for treatments of serious heart conditions.
The traditional balloon angioplasty is a common method approved by the FDA for treating blocked heart arteries. It is considered safe and is often used to prepare arteries before placing drug-eluting stents, which help keep arteries open.
Both treatments have been used in patients with heart conditions, and their safety is well-documented. While Orbital Atherectomy and balloon angioplasty carry risks, healthcare professionals manage these risks carefully.12345Why are researchers excited about this trial?
Researchers are excited about these treatments because they present unique approaches for managing coronary artery disease. Orbital Atherectomy stands out because it uses the Diamondback 360® Coronary Orbital Atherectomy System to precisely prepare the artery by sanding away calcified plaque before placing a stent. This is different from the conventional balloon angioplasty, which simply inflates a balloon to widen the artery but may not be as effective in heavily calcified vessels. The orbital atherectomy's ability to better prepare complex lesions potentially leads to improved stent placement and long-term outcomes.
What evidence suggests that this trial's treatments could be effective for coronary artery disease?
This trial will compare Orbital Atherectomy with Conventional Balloon Angioplasty for coronary artery disease. Research has shown that orbital atherectomy can effectively reduce plaque in the heart's arteries. It employs a spinning, diamond-coated tool to clear the way for stent placement, which is crucial for treating very hardened arteries. Studies have found that using this method before placing drug-coated stents can lead to fewer complications. Conversely, conventional balloon angioplasty, another treatment option in this trial, is widely used and has a strong track record of preparing arteries for stents, though it may not be as effective on very hardened areas as orbital atherectomy. Both treatments aim to improve blood flow, but the best choice depends on the specific condition of the artery.678910
