Check treatment for re-narrowing in a stent using special balloon
Part of Heart & circulation clinical trials.
This trial studies whether a DCB (drug-coated balloon) treatment can safely and effectively stop a stent from re-narrowing (in-stent restenosis), guided by a heart-echo–like pressure measurement called QFR. It may help if your artery is showing restricted flow through a previously placed stent.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have re-narrowing inside a coronary (heart) stent (in-stent restenosis)
- Your QFR measurement for the target area is below 0.8
- You do not have a major artery tear (dissection) or a blood clot that happened after initial balloon treatment
- Your heart pumping and symptoms are not severely limited (LVEF 30% or less, or NYHA class III/IV)
- You can take aspirin and/or clopidogrel (no intolerance)

This trial studies a special artery treatment called DCB (drug-coated balloon) for new (de novo) blockages in people with coronary heart disease, guided by a heart scan measurement (QFR). It aims to check whether it is safe and works well to improve blood flow and reduce problems during follow-up.
This trial tests how the way a drug-coated balloon is used during a heart procedure affects outcomes for people with stable heart disease or unstable angina. It may help doctors find the best technique to keep arteries open.
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 tests whether a special drug-coated balloon (“MagicTouch”) can treat re-narrowing inside a previously placed stent. It may help patients whose stent has become blocked again, by improving blood flow and reducing repeat narrowing.
This trial tests a drug-coated balloon to open blocked coronary arteries. It may help people with symptoms of heart disease or signs of reduced blood flow to the heart.
This study tests a drug-coated balloon (DCB) that releases two medicines (sirolimus and paclitaxel) to open blocked small heart arteries. It may help people with stable chest pain or recent, controlled heart events who have a narrowed small vessel.
