Balloon vs stent: new hope for heart patients without permanent metal?
NCT ID NCT04893291
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether a sirolimus-coated balloon works as well as a standard drug-eluting stent for opening narrowed heart arteries. About 1,820 adults with coronary artery disease will be randomly assigned to receive either the balloon or the stent during a routine angioplasty procedure. The main goal is to see if the balloon is non-inferior to the stent in preventing artery failure at one year.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Sirolimus-coated balloon (Magic Touch) and everolimus-eluting stent
- What this could lead to
- If successful, this could offer a stent-free option for opening blocked heart arteries, potentially reducing long-term complications from permanent implants.
- What could go wrong
- This is a large but early-stage comparison; the balloon may not be as effective as the standard stent, and risks like artery re-narrowing or bleeding remain.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * age \>18 years; * all patients with a clinical indication to Percutaneous Coronary Intervention (PCI) (stable coronary artery disease or acute coronary syndromes); * native coronary artery lesion in a vessel with diameter \>2.0 mm and ≦3.5 mm at visual estimation; * maximum lesion length: 50 mm. * informed consent to participate in the study. Exclusion Criteria: * patients with known (and untreatable) hypersensitivity or contraindication to aspirin, heparin, clopidogrel, prasugrel, ticagrelor, sirolimus or contrast media, which cannot be adequately pre-medicated; * patients participating in another clinical study; * subject is a woman who is pregnant or nursing (pregnancy test, either urine or blood test must be performed within 7 days prior to the index procedure in woman of child-bearing potential, and must not commit to initiating a pregnancy for 12 weeks after implantation, using effective contraception); * creatinine clearance \<30 ml/min; * left ventricular ejection fraction \<30%; * life expectancy \<12 months; * ST-elevation myocardial infarction in the previous 48 hours; * visible thrombus at lesion site; * culprit lesion stenosis \>99% and/or Thrombolysis In Myocardial Infarction (TIMI) flow \<2; * target lesion/vessel with any of the following characteristics: * concomitant PCI at the same vessel with any device (vessels are considered: left anterior descending, circumflex or right coronary artery); * pre-dilatation of the target lesion not performed or not successful (residual stenosis \>30%); * severe calcification of the target vessel, at lesion site but also proximally; * highly tortuous vessel which could impair device delivery to the lesion site following Investigator's judgement; * previous stent implantation at target vessel (left anterior descending artery; circumflex artery; right coronary artery); * bifurcation lesion where side branch treatment is anticipated; * left main stem stenosis \>50%; * target lesion is in left main stem * Lesion is located within asaphenous vein graft
