Spontaneous coronary artery dissection (SCAD) is a non-traumatic and non-iatrogenic separation of the coronary artery wall that is now recognised as an important cause of myocardial infarction, especially in younger women or those without traditional cardiovascular risk factors. Angiographic diagnosis is aided by recognizing the appearance and can be aided by OCT and IVUS. Conservative management is generally recommended, however ongoing ischemia, shock, or ventricular arrhythmias should prompt consideration of PCI or coronary bypass.
A case discussion of case of SCAD requiring mechanical support that I wrote up was published in Emergency Medicine News.
