Should the fistula be treated? Clinical symptoms Clinical symptoms Myocardial ischaemia on stress test Myocardial ischaemia on stress test Features of L-R shunt on chest X-Ray Features of L-R shunt on chest X-Ray The answer is: YES

Percutaneous closure of the coronary fistula Jomed coronary graft stent on balloon 4.0 mm LCA: RAO30/Caud15 post stent-graft implantation

6 month follow-up No angina No angina Tredmil stress test: 85% of MHR, 10 METS, no ischemia on ECG, Tredmil stress test: 85% of MHR, 10 METS, no ischemia on ECG, A control angio: no restenosis A control angio: no restenosis

6 month coronary angiography LCA: RAO30/Caud15 6 month follow-up Stented segment LCA: LL90

Conclusions Coronary fistula can be completely closed with a graft stent. Coronary fistula can be completely closed with a graft stent. Beacause of the risk of in stent restenosis a control coronary angiography should be taken after 6 month. Beacause of the risk of in stent restenosis a control coronary angiography should be taken after 6 month.
