CAE can be caused by various congenital or acquired factors. Surgical treatment, such as transcatheter embolization excision, surgical ligation or resection for symptomatic patients with CAE three times or larger than the reference diameter, has been reported to have satisfactory results. Additionally, CABG can be selected if myocardial perfusion is compromised and the distal branch is of reasonable size. In this case, the giant ectasia of the RCA may have been a consequence of the congenital RCA-LV fistula. Atherosclerosis, with calcified plaques in the RCA, and the patient's long-term history of smoking may have contributed to the development of giant ectasia of the RCA.
