Key result
OCT-guided stent-free sirolimus DCB demonstrates 15-month vessel patency without recoil in left main STEMI case.
Why the study?
Left main STEMI is typically managed with urgent stenting, but intravascular imaging shows plaque erosion may permit alternative stent-free strategies.
Does an OCT-guided stent-free sirolimus drug-coated balloon strategy provide durable vessel healing in a patient with left main STEMI and plaque erosion?

Does an OCT-guided stent-free sirolimus drug-coated balloon strategy provide durable vessel healing in a patient with left main STEMI and plaque erosion?
An OCT-guided stent-free PCI strategy using a sirolimus drug-coated balloon may offer durable healing and an alternative to permanent stenting in select young patients with left main STEMI and plaque erosion.
Supports OCT-guided conservative management in select LM STEMI; leaves open need for prospective validation before practice change.
BACKGROUND: Left 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.

Ravichandran et al. (2026) conducted a case report in Left main ST-elevation myocardial infarction (STEMI) (n=1). Stent-free sirolimus drug-coated balloon (DCB) was evaluated on Vessel patency and healing. OCT-guided stent-free sirolimus drug-coated balloon intervention in a 43-year-old man with left main STEMI demonstrated vessel patency and satisfactory healing without recoil at 15 months.
