Case 1: left CAG showed a huge aneurysm with calcification of the proximal left coronary artery, and the LAD is obstructed at the outflow of the aneurysm (red arrowhead), and the blood is supplied by the collateral circulation tract from the right coronary artery. LAD, left anterior descending artery; LCX, left circumflex artery.

CAG confirmed a huge aneurysm with calcification of the proximal left coronary artery and complete LAD occlusion at the outflow area of the aneurysm with collateral circulation from the RCA and stenosis of the left circumflex artery (LCX) (Figure 1).
Case 1: macrofindings of the LAD aneurysm during surgery. A giant coronary aneurysm prior to resection is observed. A hard and calcified mass >40 mm in diameter is present. The mass was filled with a red blood clot. LAD, left anterior descending artery.

Surgery was performed using two arterial grafts: the left internal mammary artery (LITA)-LAD and the right internal mammary artery (RITA)-PL (posterolateral branch); the giant aneurysm (45 x 35 mm, severe calcification) was resected (Figure 2).

Case 2: right and left CAG performed in the acute phase when the patient was 2 months old. (A) It exhibited a large RCA "sausage-like" aneurysm at segments 1-3 with a maximum diameter of 12 mm. (B) Let CAG exhibited aneurysms in the LAD at segment 6 with a maximum diameter is 6 mm and LCX with a maximum diameter of 3.3 mm at segment 11. CAG, coronary angiogram; RCA, right coronary artery; LAD, left anterior descending artery; LCX, left circumflex artery.

On CAG, a huge long segmental aneurysm on RCA was observed with a maximum diameter of 12 mm, the blood flow was almost arrested, and the presence of a thrombus was confirmed (Figure 3).
Case 2: right CAG at 1 year after CABG. The blood flow supply from the GEA to the distal site of RCA was adequate. CAG, coronary artery angiogram; CABG, coronary artery bypass graft surgery; GEA, gastroepiploic artery; RCA, right coronary artery.

Angiography performed at ~1 year after surgery showed a good blood flow in both vessels (Figure 4).
