A total of 13 patients underwent surgical treatment for CAFs in our
hospital from 2008 to 2019. There were five men (38%), and the mean age
was 67.3 years (45–81 years). The CAF was assessed by preoperative
coronary artery computed tomography (CT). Coronary angiography (CAG) was
performed in 11 patients (85%), and six patients (46%) underwent right
heart catheterization. This study was approved by the Ethical Committee
in Kokura Memorial Hospital (ID: 20061501, date 2020/06/05). Written
informed consent was obtained from the patients for publication of this
case report and accompanying images.
