Spontaneous coronary artery dissection is an uncommon condition, and the patients’ clinical presentation is often underestimated due to few risk factors for atherosclerotic disease. Treatment must be individualized, with conservative therapy as the first option, respecting the criteria for referral for interventional treatment. We report a case of spontaneous coronary dissection, initially manifested as a non-ST segment elevation acute coronary syndrome, progressing to transmural infarction, in a young patient, with few risk factors for coronary artery disease, and give examples of difficulties related to the percutaneous approach.

Coronary angiography showing the result of the procedure. (A) Right anterior oblique caudal view shows marginal branch dissection, maintained under conservative treatment. (B) In a right anterior oblique cranial projection, three stents are observed in the left anterior descending artery, with no opacification of the distal bed of this coronary vessel.
