Three years prior, the patient underwent coronary angiography for dyspnea. The coronary angiography examination revealed a fistula originating from the left anterior descending artery and left main coronary artery, which had soft aneurysmal sacs and most likely drained into the pulmonary artery. Parasternal short axis echocardiography revealed a color flow that could be related to the fistula, but the other echocardiographic findings were normal. The patient did not accept the proposed examination and invasive treatment.展开更多

Their prevalence is less than 1.3% based published series.1＇2 The most common coronary anomaly is separate origin of the left anterior descending coronary artery （LAD） and left circumflex coronary artery （LCX） from the left sinus of the Valsalva. The second most common anomaly is the origin of the LCX artery from the right coronary artery （RCA） or right sinus of the Valsalva. We present two cases of coronary artery anomalies： one is the left main coronary artery （LMCA） arising from the proximal RCA, the other is the LAD originating from the proximal RCA.展开更多

We occluded LAD fistulae by using thrombus aspira- tion catheter as a delivery guide. To the best of our knowlege, this is the first case of occlusion of coronary fistulaes with the help of throm- bus aspiration catheter. Our experience may suggest that thrombus aspiration catheters can be used in treating coronary artery fistulaes with difficult anotomv.展开更多
