Stent-Free Sirolimus DCB for Left Main STEMI: Acute and Long-Term OCT Follow-Up.
Article in JACC. Case reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundLeft main (LM) ST-elevation myocardial infarction (STEMI) is typically managed with urgent stent implantation according to current guidelines. Yet intravascular imaging has shown that plaque erosion may permit alternative strategies. CASE SUMMARY: A 43-year-old man with anterior STEMI and hypotension underwent angiography, revealing distal LM thrombus extending into the left anterior descending/left circumflex arteries. Postaspiration optical coherence tomography (OCT) confirmed plaque erosion without rupture. Following lesion preparation, a drug-coated balloon-only strategy was applied to all 3 vessels. Follow-ups at 20 days and 15 months confirmed vessel patency, satisfactory healing, and no recoil or neoatherosclerosis. DISCUSSION: Current guidelines lack support for stent-free LM STEMI intervention. However, OCT-guided management allows for individualized treatment in young patients by characterizing lesion biology. Long-term follow-up demonstrates successful vessel healing, suggesting that avoiding permanent metallic scaffolds in selected cases may mitigate lifelong stenting risks. TAKE-HOME-MESSAGE: OCT can identify plaque erosion and guide stent-free percutaneous coronary intervention in select left main STEMI cases, offering durable healing and flexibility in antithrombotic therapy.
