Aneurysmal coronary artery disease: An overview

  Figure 1.. Coronary artery aneurysm compared with coronary artery ectasia. (A) Coronal reformatted image of 55 year-old man with stents in the left main and proximal circumflex coronary arteries. A saccular atherosclerotic aneurysm (arrows) is seen in the mid distal portion of the left circumflex coronary artery. (B) Volume rendered image showing ectasia in the RCA, its posterolateral branch, and the left anterior descending artery (arrows). Note normal diameters (arrowheads) of the coronaries; dilatation of the coronary arteries extends for more than 50% of the vessel length. From Diaz-Zamudio et al.11 with permission.

  Figure 2.. Giant coronary artery aneurysm. (A) Coronary angiogram of a 19 year-old male patient with history of Kawasaki disease during childhood showing a “giant” coronary aneurysm affecting the mid segment of the right coronary artery. (B) 3D volume-rendered reconstructed CT image of the same patient.

  Figure 3.. Angiographic and IVUS images of coronary artery aneurysm. (A and B) Coronary artery aneurysm detected by coronary angiography and intravascular ultrasound (IVUS) 8 months after bare-metal stent implantation. (C and D) Coronary artery aneurysm detected with coronary angiography and IVUS 3 months after drug-eluting stent implantation. From Aoki et al.16 with permission.

  Figure 4.. Percutaneous treatment of a mid-LAD aneurysm. (A) Coronary angiogram of a 22 year-old male patient presenting with acute anterior ST-elevation myocardial infarction. A giant aneurysm (etiology unknown) is seen in the mid segment of the left anterior descending (LAD) coronary artery which is subtotally occluded after the aneurysmal segment. (B) TIMI 3 flow restored in the distal LAD after primary percutaneous coronary intervention using a 3.0 × 28 mm PTFE-covered stent with cessation of flow into the aneurysm.
