Read our Coronary Artery Disease research guide →This study is tracking how heart arteries respond after treatment with a drug-coated balloon, which is a special medical device used to open clogged arteries without placing a permanent stent. Researchers will take detailed heart imaging scans before the treatment and again two years later to see how the artery changes, what happens to the blockage, and whether this treatment approach works well for patients.
Drug-coated balloons are a newer option for treating clogged heart arteries, but doctors need more information about how well the arteries stay open long-term and whether this approach is as safe and effective as other treatments. This study will help answer those questions.

If you join this study, you will have already received your drug-coated balloon treatment after an initial heart imaging scan. Your main responsibility will be to return two years after your procedure for another heart imaging scan, which will show how your artery has healed. The study team will compare your two scans to see how the blockage has changed and how well the treatment worked.
