Primary Spontaneous Coronary Artery Dissections in Atherosclerotic Patients. Report of Nine Cases with Review of the Pertinent Literature

Primary spontaneous coronary artery dissection is one of the rare causes of acute myocardial infarction. Previous studies reports that it is mostly seen in middle aged women in the last trimester of pregnancy and early postpartum period. Clinical presentation of the disease is variable in pattern and severity related to extent and development rate of dissection. In the last 2 years, nine non-pregnant primary spontaneous coronary artery dissection cases were found in coronary angiography among 3750 patients prediagnosed as coronary artery disease. The cases were presented and discussed with review of the pertinent literature.
