Application of interventional diagnostic and therapeutic technique for coronary artery fine branch fistula

Objective：To explore the value of angiographic diagnosis and interventional therapy of the coronary artery fine branch fistula. Methods：All of the 18 patients with coronary artery fine branch fistula underwent selective coronary arteriography, 7 underwent interventional therapy, while 8 underwent prosthesis for coronary artery fistula （CAF） under extracorpored circulation. Results：Among 18 cases of coronary artery fine branch fistula, 7 happened in right coronary artery （38. 9%）, 11 in left coronary artery （61. 1%）. Among the 11 cases in left coronary artery,5 happened in descending anterior branch, 5 occurred in left circumflex branch, 1 arised from both left anterior branch and left circumflex branch. Among the 18 cases, there are 10 cases of coronary-to-pulmonary artery fistula （55.6%）, 5 cases of fistula draining into right atrium （27.8%）, 2 cases of fistula draining into left atrium （1 1.1% ） and 1 draining into right ventricle （5.6%）. Interventional treatment was successful in 7 patients. During the 12 months＇ follow-up, there was no cardiovascular events. Conclusion： Selective coronary angiography is the first choice for diagnosing the coronary artery fine branch fistula. In respect of therapy, besides of surgical treatment, intervention is still a rather good measure presently.
