Comparing two guidewires for twisted wrist arteries during heart tests
Part of Cancer clinical trials.
This trial compares two different types of thin wires (guidewires) used during a coronary angiogram to see which one works better when your wrist artery has a twist or loop. The goal is to make the procedure smoother and safer for people with this common variation.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 years old or older.
- You need a coronary angiogram (a test to look at your heart's arteries).
- Your wrist or arm artery (radial or brachial) has a twist or loop seen on a previous angiogram.
- You are not having a heart attack or a very unstable heart condition.
- You do not have heavy calcium buildup in your wrist or arm artery.

This study compares two ways of accessing the heart's blood vessels through the wrist artery during a heart imaging procedure. Researchers will test whether using ultrasound to guide the needle improves the success and safety of the procedure.
This trial looks at using the ulnar artery in the wrist instead of the radial artery for heart catheterization or stent placement, when the radial artery on that side is blocked. It may be an option for people who cannot use the other arm's radial artery.
This trial compares two sizes of small tubes (called sheaths) used during a heart procedure to open blocked arteries. The procedure is done through a tiny artery in your wrist, and the goal is to see if a smaller tube works just as well with fewer side effects.
This trial tests which technique works better for placing a small tube in the wrist artery for monitoring during heart surgery. It compares the standard method to one using ultrasound guidance to find the best approach for patients with difficult wrist arteries.
This study compares two ways to access the wrist artery for heart catheterization—one at the wrist and one slightly higher in the forearm. Researchers use ultrasound to check for any injury to the artery before you go home.
This study compares using the wrist (radial artery) versus a different access site (conventional radial access approach) during complex, larger “bore” heart procedures to open blocked coronary arteries. It aims to see which approach is safer and works better for challenging cases like chronic blockages or heavily calcified arteries.
