Spontaneous Coronary Artery Dissection: Efficient Clinical Outcome through Percutaneous Coronary Intervention

Spontaneous coronary artery dissection (SCAD) is a rare myocardial ischemic disease that threatens patients' life. Various risk factors are associated with SCAD, such as smoking, severe hypertension and psychological reasons. Considering the formation of dissection, SCAD can be divided into intimal tear type or intraluminal hemorrhage type. The clinical presentation of SCAD depends on the extent and severity of progression of dissection and may present as unstable angina, acute myocardial infarction, ventricular arrhythmias or asymptom. Treatment of SCAD usually includes percutaneous coronary intervention (PCI), bypass graft surgery or medical therapy depending on the range of dissection. Herein, we report a 70 years-old male diagnosed with dissection in the left anterior descending artery by coronary arteriography. Despite the patient's exposure to the ventricular arrhythmias, he had a good prognosis and survived at 2 years of following up. We found PCI treatment is suitable for the patient who had SCAD.
