Coronary stenting with cardiogenic shock due to acute ascending aortic dissection

Figure 3 Coronary angiography and intravascular ultrasound findings prior to stent implantation. IVUS shows compression of the true lumen from the LMCA ostium to the LAD by a large false lumen. A: The large hematoma (arrowhead) eviscerates into the aorta (Ao); B: The false lumen (arrowhead) compresses the LMCA (LM), including both the LAD and LCX ostium. The arrow indicates the guidewire in the LCX; C: The large false lumen (arrowhead) compresses the true lumen (T) in the proximal LAD; D: The false lumen disappears before the bifurcation of the diagonal branch. Scale measures in 1 mm. IVUS: Intravascular ultrasound; LCX: Left circumflex artery; LAD: Left anterior descending artery.
