Percutaneous Coronary Intervention for Spontaneous Coronary Artery Dissection under Intravascular Ultrasound Guidance

A 77-year-old woman underwent percutaneous coronary intervention (PCI) for a spontaneous coronary artery dissection (SCAD) lesion in right coronary artery. A guide wire was advanced to the dissecting lesion, but it was inserted into false lumen. Therefore, we advanced an intravascular ultrasound (IVUS) catheter over the false lumen guide wire. The IVUS observation from the false lumen was useful for navigating the second guide wire into the true lumen. Finally, 38 mm everolimus-eluting stent was successfully placed in the dissecting lesion with fully coverage. The IVUS guidance such as in this case would be promising for the PCI in SCAD case.
