Intracoronary imaging showed stent mal-apposition of up to 990 microns due to intramural hematoma resorption after PCI in patients with spontaneous coronary artery dissection (SCAD).
In patients with SCAD undergoing PCI, resorption of intramural hematoma can lead to late stent mal-apposition, suggesting a role for OCT follow-up to guide dual antiplatelet therapy duration.

Spontaneous coronary artery dissection (SCAD) is an infrequent cause of acute coronary syndrome (ACS). Conservative management is typically recommended but revascularization may be necessary if ongoing ischemia or adverse anatomical characteristics are present. Percutaneous coronary intervention (PCI) of SCAD can be fraught with challenges, and intracoronary imaging with optical coherence tomography (OCT) may provide insights on optimizing the acute results and identify long-term stent-related adverse events. We report three cases of SCAD treated with drug-eluting stents (DES) with OCT follow-up showing stent mal-apposition at different stages of follow-up. The clinical significance of these OCT findings and management options are discussed.
Lempereur et al. (Sat,) conducted a other in Spontaneous coronary artery dissection (n=3). Drug-eluting stents (DES) was evaluated on Stent mal-apposition and outcomes after PCI (null, 95% CI null, p=null). Intracoronary imaging showed stent mal-apposition of up to 990 microns due to intramural hematoma resorption after PCI in patients with spontaneous coronary artery dissection (SCAD).
