Novel insights on spontaneous coronary artery dissection

摘要

Spontaneous coronary artery dissection (SCAD) remains an elusive and challenging clinical entity of unknown etiology eight decades after its initial pathological recognition [1]. Coronary angiography has been classically used for the diagnosis of these patients [2-6]. A radiolucent intimal flap, separating the true lumen from the false lumen, has been considered as the hallmark of the disease [2-6]. Multiple case reports and small retrospective series with limited clinical follow-up have been published but the total number of patients with SCAD reported to date is less than 700 [2-6]. This largely explains the limited information currently available on prevalence, predisposing conditions, pathophysiol-ogy, diagnosis, management and prognosis of patients with SCAD [2-6].
