A 36-year-old female, with no cardiovascular risk factors, was examined with angina pectoris. Electrocardiogram showed T wave inversion in D2, D3 and aVF surface leads. The patient was submitted to coronary angiography that showed an image suggestive of spontaneous coronary dissection on the proximal segment of the right coronary artery, severely compromising arterial lumen and flow. Additional evaluation included intravascular ultrasound, which guided the subsequent percutaneous coronary intervention with stent implantation and assessed the final result. Spontaneous coronary dissection is a rare cause of acute coronary syndrome and affects mainly young women in the gestational age. Little is known about its pathophysiology. Prognosis and treatment depend on the length of dissection and the compromised artery.
