OCT vs. X-ray guidance for treating re-blocked stents
Part of Heart & circulation clinical trials.
This study compares the standard X-ray guidance (angiography) with a more detailed imaging test (OCT) to guide treatment for a re-blocked stent. It aims to see which method leads to better outcomes for patients with in-stent renarrowing.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 years or older.
- You have a blocked stent (in-stent restenosis) that is 70% to 99% closed on at least two X-ray views.
- Your blood vessels are wide enough (≥ 2.25 mm and ≤ 5.75 mm) for the imaging catheter.
- You have stable vital signs (blood pressure, heart rate) before the procedure.
- You are not already in another clinical trial with an experimental treatment.
- Your doctor can safely perform a special imaging test (OCT) inside the blocked vessel.

This study looks at how well doctors can treat multiple blocked heart arteries using a specific drug-eluting stent, aiming to fully open them. It may help patients whose blockage pattern fits the study, but it does not include certain high-risk or special cases.
This study compares how best to place a coronary stent (a small tube to keep an artery open) using modern techniques. It may help improve how safely and effectively stents are delivered in people with certain types of narrowed heart arteries.
This study looks at how to treat blocked heart arteries that have narrowed again after a prior drug-eluting stent. It compares using another drug-eluting stent versus a drug-coated balloon, chosen based on an imaging scan inside the artery (OCT), to reduce repeat narrowing.
This trial compares two imaging and pressure tests used during stent placement to see which helps improve blood flow better in people with chest pain or a recent heart attack.
This trial uses a type of imaging called OCT to look inside heart arteries and help doctors decide the best treatment for people with certain types of coronary heart disease. It aims to see if this advanced imaging can improve outcomes.
This study compares two ways of guiding a heart stent procedure: using information from a special angiography scan versus using standard practice. It may help your care team choose the best treatment to improve heart outcomes after stenting.
