Key result
Stingray-based ADR with drug-coated balloon achieves TIMI 3 flow and 3-month healing in traumatic LAD dissection.
Why the study?
Traumatic coronary artery dissection (TCAD) is a rare catastrophic complication of blunt chest trauma that is often masked by concomitant injuries, posing diagnostic and therapeutic challenges.

In a young polytrauma patient with traumatic coronary artery dissection and high bleeding risk, a stentless PCI strategy using antegrade dissection and re-entry with drug-coated balloon angioplasty successfully restored coronary flow and improved cardiac function.

Hypothesis-generating for stentless recanalization in traumatic coronary dissection; prospective validation required before clinical adoption.
BACKGROUND: Traumatic coronary artery dissection (TCAD) is a rare catastrophic complication of blunt chest trauma, often masked by concomitant injuries, posing diagnostic and therapeutic challenges. CASE SUMMARY: A 20-year-old man with polytrauma after a motorcycle accident developed cardiogenic shock. Coronary computed tomography angiography (CCTA) suggested occlusive left anterior descending dissection, confirmed by delayed angiography under extracorporeal membrane oxygenation support. Stingray-based antegrade dissection and re-entry (ADR) with cutting balloon fenestration and drug-coated balloon angioplasty achieved TIMI flow grade 3. Three-month follow-up showed favorable left anterior descending healing and improved cardiac function. DISCUSSION: CCTA enables early TCAD diagnosis. ADR facilitates guidewire passage, and a stentless strategy is preferable in young polytrauma patients at high bleeding risk. TAKE-HOME MESSAGES: Maintain suspicion for TCAD after blunt chest trauma, especially with ST-segment elevation myocardial infarction features. CCTA aids early diagnosis; ADR-based percutaneous coronary intervention with drug-coated balloon is safe and effective.

Fu et al. (2026) conducted a case report in Traumatic coronary artery dissection (occlusive left anterior descending dissection) and cardiogenic shock (n=1). Stingray-based antegrade dissection and re-entry (ADR) with cutting balloon fenestration and drug-coated balloon angioplasty was evaluated on Coronary recanalization (TIMI flow grade) and vessel healing. Stingray-based antegrade dissection and re-entry with drug-coated balloon angioplasty achieved TIMI flow grade 3 and favorable LAD healing at 3 months in a 20-year-old with traumatic dissection.
