An 11-year-old male patient with a clinical history of psychomotor development delay and ventricular preexcitation required several follow-up visits at another service. No other cardiovascular-associated symptoms were described. Since the family moved home, the child was referred to our hospital. A transthoracic echocardiogram (TTE) was performed as part of standard evaluation in the first appointment, revealing anatomical changes of the coronary arteries. Further investigation included cardiac computed tomography (CT) which showed multiple aneurysmal dilations along the path of the right coronary artery (RCA), the largest measuring 10x10mm, in the proximal segment (Figure 1A). Cardiac catheterization was performed, and five aneurysms in the RCA were identified: a more proximal (18x11mm), one giant in the middle third (7x20mm) and three more distal (5.2mm; 5.5mm; 6mm in diameter) (Figure 1C and 1D). The left coronary artery presented a prominent ectasia (proximal diameter of 3mm; distal diameter of 5.4mm) of the common trunk, with a 50% stenosis of the middle third of the left anterior descending artery (Figure 1E).
