Among the 34 CAF patients diagnosed by CTCA, 11 cases (male: five; female: six; age range: 21-67 years) performed invasive CAG, which included seven cases of CPAFs, three cases of coronary right atrium fistulas, and one case of coronary SVC fistula.
Nakamura et al . reported that 50% of CAF cases arise from the RCA, 42% from the LCA, and 5% from the RCA and LCA.
Both surgical and percutaneous embolization were reported to be effective and safe., In the present study, 11 CAF patients performed CAG and nine of them underwent surgical treatment, the operation ligated the CAF and treated other abnormalities such as aneurysm and coronary artery stenosis.
Results: Total 8 cases of attempted CAF device closure were included with mean age of 13 years and male to female ratio of 1:1.
Conclusion: Transcatheter occlusion of CAF by various occluder devices is an effective therapeutic option with high success rate.
Isolated Coronary artery fistula (CAF) are one of least common cases encountered in pediatric catheterization laboratory and defined as an abnormal linking between one or more coronary arteries and an adjacent cardiac chamber or vascular structure1-3.
