Abstract
Spontaneous coronary artery dissection (SCAD) is a non-traumatic, non-iatrogenic, and non-atherosclerotic separation or dissection of the coronary arterial wall by the formation of an intramural hematoma causing a false lumen leading to compression of the true lumen with a varying degree of coronary blood flow obstruction. One of the important and frequent complications of the disease is the in-hospital and long-term SCAD recurrence. SCAD associated with takotsubo syndrome (TS) has been described in case reports, series of cases and in some studies. Some investigators believe that the association of SCAD and TS is a misdiagnosis. The association of SCAD and fibromuscular dysplasia (FMD) has received major attention during the last 10 years. In this report, the short and long-term SCAD recurrence, SCAD association with TS and FMD are reviewed and demonstrated with illustrative images.
