| 2 | Male | 6 months | 3 years and 6 months | Significant enlargement of the left ventricle with LVEF of 50%; a nodule in the proximal segment of LAD; 2 sites of dilatation in the RCA without clear display of the distal segment | Torsion and stenosis of the main trunk of RCA with collaterals formation; the LAD without significant lesions | 7 years and 6 months (chest pain for 10 d) | The proximal segment of RCA was severely narrow or atresia with several collaterals formation, and the distal segment displayed well |
| 3 | Male | 3 years | 3 years and 3 months | A large aneurysm in the proximal segment of LAD; a beaded dilatation in RCA | A medium coronary aneurysm in the proximal segment of LAD and post-aneurysm coronary artery occlusion with collaterals formation; beaded dilatations in the RCA without filling defects | 4 years and 3 months | The blood flow of LCX was unobstructed; three aneurysms in the RCA progressed, of which diameters were wider than before, and filling defects could be seen in the RCA |
| 4 | Male | 4 months | 4 years | A medium aneurysm in the proximal segment of LAD and a medium aneurysm in the proximal segment of RCA, and the coronary arteries not clear after the 2 aneurysms | Small aneurysms in the middle section of RCA with calcification and collaterals formation; stenosis in the proximal segment of LAD without coronary artery formation | 6 years | The stenosis in the LAD progressed, and the diameter of the narrowest point was 1.2 mm. Intraoperative balloon dilation was performed, and then the blood flow was unobstructed |
| 5 | Female | 2 years and 4 months | 3 years | A large aneurysm in the LM; the opening of LCX dilated with thrombosis formation; a small aneurysm in the proximal segment of RCA with thrombosis after the aneurysm | A large aneurysm in the LM with the stenotic LAD; a small aneurysm at the beginning of RCA with post-aneurysm atresia and collaterals formation | 3 years and 9 months | The aneurysm in the LM progressed with narrower LAD; proximal coronary atresia of the RCA was found with collaterals formation |
| 6 | Male | 2 years | 5 years | A large aneurysm in the proximal segment LAD with thrombosis and without clear display of the distal segment; the RCA dilatated in the middle segment | The blood flow was unobstructed in the LAD; small artery dilatations in the LAD and the distal segment of RCA | 7 years | The diameter of the opening of RCA was 3.1 mm, while the stenosis in the proximal segment was 2.01 mm in diameter, and a beaded dilatation in RCA after the stenosis |
| 7 | Male | 9 years | 12 years (2 times of syncope in 3 years) | The LM dilatated; a large aneurysm in the LAD; beaded dilatations in the RCA | A medium aneurysm in the LAD with a post-aneurysm coronary atresia and calcification formation; 3 beaded coronary aneurysms in the RCA | 15 years | Thrombosis at the beginning of LAD with atresia and calcification after the thrombus; the RCA supplied the LAD by collaterals in reverse direction |
| 8 | Female | 2 years | 3 years | A large aneurysm in the LAD without clear display of the distal segment | A dilatation at the beginning of LAD, about 6.3 mm in diameter, with filling defection and thrombosis formation after the dilatation | 4 years and 5 months | A aneurysm with the diameter of about 8.5 mm at the openings of LCX and LAD (bifurcation of LM) |
