The tortuous dissection image compromising proximal, middle and distal third (I) involving the origin of the posterior and downward ventricular branches. Anterior descending artery with atheromatous plaque and image dissected after origin of the first septal branch, involving the origin of the first two diagonal branches (III)

The right coronary artery had good caliber, tortuous dissection image compromising proximal, middle and distal third involving the origin of the posterior and downward ventricular branches (Figure 1). Anterior descending artery (aDA) with atheromatous plaque and image dissected after origin of the first septal branch, involving the origin of the first two diagonal branches (Figure 1).
The anterior descending artery (aDA) displays mixed noncalcified plaques with 80% obstruction in the middle third (I/III). The right coronary artery (aCD) has a thick wall plate and calcified source and reduced lumen of about 50% at the distal end (II/IV)

Patient underwent angiography of coronary arteries about two months after the diagnosis of SDCA that only showed multivessel atherosclerotic disease, with significant reduction of the lumen in aDA and to a lesser extent in the lumen of the right coronary artery (RCA) (Figure 2).
