Case description
A 31-year-old female, with the symptom of dyspnea after exercise for 3 years. After being admitted to the hospital, coronary computed tomography angiography (CTA) revealed the formation of CAAs in the proximal left anterior descending artery and proximal right coronary artery with severe calcification, the dimensions were 2.5cm×1.6cm×2.0cm and 1.4cm×1.3cm×2.0cm respectively. (Figure 1). Coronary angiography showed the middle part of left anterior descending branch (LAD) was stenosis 90%, TIMI grade 1, 90% stenosis in the middle of RCA (Figure 2). The electrocardiography (ECG) showed normal sinus rhythm (Figure 3), and the outline of two coronary aneurysms can be seen on chest X-ray radiography (Figure 4). The echocardiogram showed LVED was 49mm, LA was 29mm, and the EF was 60%. The carotid artery CT showed that the lumen of the innominate artery. The carotid arteries, internal carotid arteries, external carotid arteries, bilateral subclavian arteries, and vertebral arteries were smoothly and without any narrowing by atheromatous plaque (Figure 2). The patient underwent coronary artery bypass graft. The left internal mammary artery and left radial artery were harvested, then bypass surgeries of the left internal mammary artery to LAD and the left radial artery to RCA were performed. Follow-up 3 months after discharge, the patient was uneventful.
