Endovascular imaging of angiographically invisible spontaneous coronary artery dissection.
Combined Use of IVUS and OCT in SCD(A) Coronary angiography showing a right coronary artery without significant coronary stenosis. (B) IVUS imaging disclosing the presence of a large space (asterisks) separating the intimomedial membrane from the external elastic membrane. The coronary lumen was largely preserved (minimal lumen diameter: 3.5 mm). (C) OCT unraveling (arrow) the intimal tear in the proximal right coronary artery with an anfractuous entrance into the coronary vessel wall. (D) An image of intramural hematoma was demonstrated in the mid and distal segments of the vessel. In most segments, the outer boundaries of the vessel ...
