1/26. Acquired internal mammary artery to pulmonary artery fistula following bypass surgery.We report two patients with acquired fistulas between the internal mammary and pulmonary arteries after coronary bypass surgery. This is a rare complication of bypass surgery and may be a cause of recurrent angina postoperatively due to coronary artery steal. A table of all the cases reported in the literature is compiled.- - - - - - - - - - ranking = 1keywords = angina (Clic here for more details about this article) |
2/26. Unstable angina following acute MI in a patient with bilateral coronary artery fistulae: an unusual presentation of coronary steal?We report a 57-year-old woman with acute myocardial infarction and cardiac arrest who subsequently developed unstable angina. The possibility of a coronary steal syndrome contributing to her unstable angina arises in view of the presence of bilateral coronary artery fistulae between two atherosclerotic coronary arteries and the main pulmonary artery.- - - - - - - - - - ranking = 6keywords = angina (Clic here for more details about this article) |
3/26. Post-coronary artery bypass grafting left internal mammary artery to pulmonary artery fistula: a 6 year follow-up following successful surgical division.We report a case of young male patient who developed left internal mammary artery to pulmonary artery fistula 9 years following the coronary artery bypass grafting operation. The clinical signs and symptoms were very subtle including recurrence of angina and heart murmur. Surgical division of the fistula and re-grafting of blocked coronary arteries resulted in satisfactory long term outcome.- - - - - - - - - - ranking = 1keywords = angina (Clic here for more details about this article) |
4/26. myocardial ischemia secondary to a large coronary-pulmonary fistula--a case report.Coronary-pulmonary fistulas are rare. The majority of these fistulas arise from the left anterior descending or the right coronary arteries; the circumflex coronary artery is rarely involved. The majority of patients are asymptomatic, but heart failure, angina, myocardial infarction, endocarditis, and dyspnea have rarely been reported. The management is controversial and recommendations are based on anecdotal cases or very small retrospective series. A case of a 62-year-old female is reported who presented with chest pain and was found to have myocardial ischemia on SPECT sestamibi. cardiac catheterization revealed no obstructive coronary artery disease and a large coronary pulmonary fistula communicating from the left circumflex coronary artery to the left pulmonary artery.- - - - - - - - - - ranking = 1keywords = angina (Clic here for more details about this article) |
5/26. Successful concomitant treatment of a coronary-to-pulmonary artery fistula and a left anterior descending artery stenosis using a single covered stent graft: a case report and literature review.This report describes a case of a 47-year-old man who presented with early post-Q wave myocardial infarction angina and an atherosclerotic left anterior descending stenosis associated to a coronary-to-pulmonary artery fistula. Both coronary stenosis and fistula were successfully treated with a single polytetrafluoroethylene-covered stent graft implantation by intravascular ultrasound-guided procedure.- - - - - - - - - - ranking = 1keywords = angina (Clic here for more details about this article) |
6/26. Internal mammary to pulmonary artery fistula presenting as early recurrent angina after coronary bypass.A 50-year-old man developed recurrent angina 1 year after coronary artery bypass surgery. The patient was found to have a large fistula involving branches of the internal mammary artery graft and the left pulmonary artery. In the absence of another clear cause for the patient's symptoms, we speculated that our patient's angina and abnormal stress nuclear study were due to coronary steal. In patients with a history of coronary bypass grafting, fistula formation between graft and native vessels should be considered as a possible cause of early recurrent angina.- - - - - - - - - - ranking = 7keywords = angina (Clic here for more details about this article) |
7/26. Fistulous connection between internal mammary graft and pulmonary vasculature after coronary artery bypass grafting: a rare cause of continuous murmur.A 58-year-old male who had undergone coronary artery bypass grafting (CABG) using left internal mammary artery and a sequential saphenous vein graft 2 years ago presented with new onset angina. His initial physical examination revealed an unexpected continuous murmur over the left sternal border, and two-dimensional echocardiography has failed to identy the cause. cardiac catheterization then performed and revealed patent left internal mammary artery and saphenous vein grafts. Besides, selective injection of the left internal mammary artery graft also showed a fistula formation between left internal mammary artery graft and pulmonary vasculature of the left upper lobe. He was managed conservatively because of the severely diseased left anterior descending artery distal to internal mammary artery anastomosis and low pulmonary artery pressure. The development of fistulous connection between internal mammary artery and pulmonary vasculature is an extremely rare complication following CABG. patients with such fistulae usually present with chest pain due to coronary steal syndrome. A new heart sound, especially a continuous murmur, may be detected during physical examination. Surgical correction is indicated in the event of refractory angina, growing fistula causing heart failure or endarteritis. Otherwise, a conservative approach with instruction of the patient for prophylactic precautions of subacute bacterial endocarditis may be recommended for asymptomatic patients.- - - - - - - - - - ranking = 2keywords = angina (Clic here for more details about this article) |
8/26. myocardial ischemia due to a coronary-pulmonary fistula treated with coil embolization.We describe one case of myocardial ischemia due to a coronary-pulmonary fistula, successfully treated with coils. Coronary fistulae are a rare cause of angina in adults with normal coronary arteries. Percutaneous treatment represents an alternative to surgery and may be offered as a relatively low risk procedure. The choice between surgical and percutaneous treatment must take into account clinical and anatomical considerations.- - - - - - - - - - ranking = 1keywords = angina (Clic here for more details about this article) |
9/26. Coronary artery aneurysms and coronary artery fistula as a cause of angina pectoris.Coronary artery aneurysm is an uncommon disease. Coronary artery fistulae are infrequent congenital anomalies. A extremely rare case report of combination of coronary artery aneurysms and coronary artery fistula is presented with a brief literature review.- - - - - - - - - - ranking = 4keywords = angina (Clic here for more details about this article) |
10/26. myocardial ischemia due to a coronary-to-pulmonary artery fistula proximal to an intermediate stenosis in the left anterior descending coronary artery: percutaneous closure by means of angioplasty and stent grafting.This case report refers to a 46-year-old patient with symptomatic stable angina and myocardial ischemia documented at 99mTc-MIBI SPECT scintigraphy. coronary angiography revealed a coronary artery fistula (CAF) and a non-significant stenosis of the left anterior descending coronary artery (LAD). We performed coronary angioplasty and stenting of the LAD and closure of the CAF using a covered stent. After the procedure the patient was asymptomatic and a myocardial scintigraphy, performed 6 months later, confirmed the absence of myocardial ischemia. This suggests that a CAF arising before a coronary stenosis may contribute to the genesis of myocardial ischemia, perhaps by giving rise to a steal phenomenon.- - - - - - - - - - ranking = 1keywords = angina (Clic here for more details about this article) |
