Rationale: Spontaneous coronary artery dissection (SCAD) is a rare, complex disease, and nowadays poorly understood. The overall incidence of SCAD ranges from 0.28% to 1.1% in angiographic studies. Therefore, the true incidence of SCAD is most likely underestimated due to asymptomatic or sudden cardiac death before diagnosis. Stent fracture (SF) is a multifactorial issue. Longer vessel remodeled by 2 stents can be more prone to have SF due to higher radial force.
Patient concerns: In this paper we report a 48-year-old man with chest pain for 2 years.
Diagnoses: Elective coronary angiography revealed a linear dissection in obtuse marginal branch (OM).
Interventions: He underwent percutaneous coronary intervention (PCI) with the guidance of intravascular ultrasound (IVUS).
Outcomes: Then SF was revealed 9 months later.
Lessons: This is the first case report of SF after coronary intervention therapy in SCAD patients.
