Spontaneous coronary artery dissection: Two case reports and a brief review

Spontaneous coronary artery dissection (SCAD) is an unusual, special type of coronary heart disease characterized by various symptoms, such as chest pain, ST-elevation acute coronary syndrome (ACS), ventricular arrhythmia, and sudden cardiac death. Here, we report two different cases who presented with ACS and were found through coronary angiography (CAG) and intravascular ultrasound (IVUS) to have SCAD, but for whom follow-up CAG and IVUS 3 months later showed different outcomes.
