Abstract
A 35-year-old woman was admitted to our hospital because of a sudden cardiac arrest caused by an acute anterior myocardial infarction. Emergency coronary angiography showed total occlusion of the proximal left anterior descending artery (LAD). We performed an intravascular ultrasound (IVUS) to detect the LAD orifice and successfully inserted the guidewire to the occluded LAD. An IVUS revealed coronary dissection and no atheromatous plaque from the orifice to the mid-portion of the LAD and the guidewire was in the true lumen. Two bare metal stents were implanted in the proximal and mid portion of the LAD. After stenting to the LAD, coronary dissection retrogradely extended to the left circumflex artery (LCx). Therefore, we performed additional stent implantation from the left main trunk (LMT) to the proximal LCx and the just proximal LAD. An IVUS guided percutaneous coronary intervention (PCI) enabled complete revascularization to spontaneous coronary artery dissection.
