Objective: Unusual clinical course Background: Spontaneous coronary artery dissection (SCAD) is a well-known cause of acute coronary syndrome. ST-segment elevation myocardial infarction (STEMI) is the most common presentation of SCAD, which can be complicated by sudden cardiac death (SCD). Conservative management is the cornerstone of treatment except in case of ongoing ischemia or large myocardial compromise. Case Report: A 34-year-old woman presented with an anterior STEMI, diagnosed by the Emergency Medical Service (EMS) team, which performed fibrinolysis. SCD resulting from ventricular fibrillation occurred soon after thrombolysis was started. Her pulsed was palpable following defibrillation, and she was immediately intubated. A coronary angiogram (CA) showed total occlusion with dye staining contrast of the proximal left anterior descending (LAD) coronary artery. Echocardiogram showed a severe drop in the left ventricular ejection fraction (LVEF 20%). She was treated with dobutamine and intra-aortic balloon pump implantation because of her poor hemodynamic status. Rescue angioplasty was performed with a drug-eluting stent implanted from the left main stem toward the proximal LAD. However, she developed hemorrhagic shock due to active liver bleeding that was surgically treated. At 3 months, she was asymptomatic, her LVEF had improved (45%), and elective CA showed quite normal coronary arteries. Optical coherence tomography showed residual hematoma as “lunar crescent” and stent under-expansion. The latter was fixed by post-dilatations. Conclusions: Our case adds to the evidence that thrombolysis leads to poor outcomes in patients with SCAD, as reported in numerous reports. OCT was used to confirm, a posteriori, the diagnosis of SCAD. Rescue angioplasty was necessary in our patient due to poor hemodynamic status following unsuccessful fibrinolysis.
