Keywords: Dual left anterior descending coronary artery • Coronary artery anomaly • Multi-slice computed tomography • Coronary artery bypass grafting
A 57-year old male presenting with unstable angina underwent off-pump coronary artery bypass grafting (CABG). A 64-slice computed tomography was able to demonstrate type IV dual left
anterior descending coronary artery much more clearly than coronary angiography (Fig. 1), which proved very helpful in performing the successful CABG (Fig. 2).
Figure 1: (A) Preoperative coronary angiography (CAG) showing obstruction of the right coronary artery (white arrowhead) and a severely stenotic conus branch (black arrowhead). (B) Preoperative 64-slice computed tomography confirming type IV dual left anterior descending coronary artery (LAD). A 64-slice computed tomography also enabled one to identify the long LAD in the dual LAD that had manifested as the conus branch in the CAG. RV: right ventricle; LV: left ventricle; AIVS: anterior interventricular sulcus.
