MUNOZ C, Cecilia et al. Spontaneous coronary artery dissection: Report of two cases. Rev. méd. Chile [online]. 2016, vol.144, n.2, pp.257-261. ISSN 0034-9887.  http://dx.doi.org/10.4067/S0034-98872016000200016.

Spontaneous coronary artery dissection is a rare condition that usually causes a coronary syndrome, but may also cause sudden death. It is more common in women and is associated with factors such as the peripartum period and oral contraceptive use. We report two cases. A 45-year-old woman with hepatitis C, presenting in the emergency room with angina. An intravascular ultrasound showed a dissecting hematoma involving the left, anterior descending and circumflex coronary arteries. She was initially managed with nitroglycerin, anticoagulation and anti-platelet drugs but due to persistence of symptoms, she required surgical revascularization. A 32-year-old woman presenting in the emergency room with angina. A coronary angiogram revealed a dissection of the anterior descending coronary artery. Eight days later an intravenous ultrasound showed a retrograde progression of the dissection and she was subjected to a surgical revascularization.
