Prophylactic and therapeutic embolization of coronary-bronchial artery fistula in patient with Bronchiectasis

(LCX) coronary artery communicated with a branch of the bronchial artery (Fig. 1). The left ventricular ejection fraction was 60% based on echocardiography. We suspected that the stenosis of the LAD coronary artery contributed to the chest pain, and decided to treat with an anti-angina drug for this lesion. We reasoned that the coronary-to-bronchial artery fistula might be secondary to coronary artery stenosis inducing a steal phenomenon in patient with bronchiectasis. If the hemoptysis recurs at the coronary-to-left bronchial artery fistula, it may be accompanied by complications, such as myocardial infarction, and increase the risk of mortality during embolization. Therefore, we advised the patient to undergo prophylactic cardiac catheterization with embolization to close the
