A case report of spontaneous coronary artery dissection complicated by stent fracture

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 card...

Sumario: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.
