Resolution of spontaneous coronary artery dissection within 3 weeks detected by computed tomography angiography and intravascular ultrasound

A 62-year-old woman was admitted with chest pain lasting about 3 h. Spontaneous coronary artery dissection (SCAD) was detected in the left anterior descending artery (LAD) by intravascular ultrasound (IVUS). Sixteen days after onset, follow-up computed tomography angiography was performed and revealed shrinkage of the false lumen of the SCAD. On hospital day 22, IVUS image confirmed that the SCAD in the LAD was completely healed. This case shows the possibility of rapid healing of SCAD.
