Multidetector computed tomography (MDCT) revealed a severe dissection of the aortic sinus, but evaluating the patency of the LAD was made difficult because of interference from the coronary stent (Figures 1A,B).
Visualization of the coronary angiography. (A) Intraoperative open-heart coronary angiography shows no significant stenosis in the left coronary artery. (B) Intraoperative open-heart coronary angiography shows no significant stenosis in the right coronary artery. LAD, left anterior descending coronary artery; LCX, left circumflex coronary artery.

A pump was used to inject 5 milliliters of contrast medium (loperamide, 300 mg iodine/mL, Ultravist, Bayer, Berlin, Germany) at a pressure of 1,000 psi and a flow rate of 4 mL/s, showing no significant coronary artery stenosis in the coronary artery (Figures 2A,B).
