Doppler findings in a rare coronary artery fistula.
(33/89)
One of the primary forms of congenital anomalies of the coronary arteries is coronary artery fistula (CAF). It is defined as a direct communication between the coronary artery and any surrounding cardiac chamber or vascular structure, which bypasses the myocardial capillary bed. We present a newborn baby with a large coronary artery fistula connecting the left anterior descending (LAD) artery to the left ventricular (LV) apex. Associated cardiac abnormalities were found: a ventricular septal defect (diameter 4 mm), a patent foramen ovale as well as trivial tricuspid and mitral regurgitation. Here we demonstrate the echocardiograms of an extremely rare form of CAF diagnosed within the first days of postnatal life. (+info)
Idiopathic transdural anastomoses in elderly patients with atherosclerotic ischemic cerebrovascular disease. Two case reports.
(34/89)
Two patients with atherosclerotic ischemic cerebrovascular disease presented with transdural anastomoses. A 74-year-old woman had a cerebral infarct, and a 76-year-old man had dementia. Patients with atherosclerotic ischemic cerebrovascular disease may have developed transdural anastomoses, so care must be taken not to damage these functions during revascularization surgery. (+info)
Coronary artery-pulmonary artery fistula: case report.
(35/89)
BACKGROUND: Coronary artery fistulas are rare congenital or acquired coronary artery anomalies that can originate from any of the three major coronary arteries and drain in all the cardiac chambers and great vessels. CASE PRESENTATION: An 11-year-old boy was referred for evaluation of an exertional dyspnoea. He reported recent history of few episodes of shortness of breath associated with moderate entity physical activity. At physical examination a mild continuous murmur could be heard mainly at the level of the second intercostal space of the left parasternal area. A transthoracic echocardiogram showed a continuous flow at color Doppler analysis in the high parasternal short axis view, originating from a small entry site on the wall of the main pulmonary artery. A selective left coronary angiography revealed a fistula connecting the proximal portion of the left anterior descending coronary artery with the main pulmonary artery. CONCLUSION: A combination like the one described in the present case is unusual since fistulas originate from the left coronary artery in about 35% of cases and drainage into the pulmonary artery occurs in only 17%.

Stent-graft exclusion of multiple symptomatic coronary artery fistulae.
(36/89)
Coronary artery fistulae may be congenital or acquired abnormalities in which blood is shunted into a cardiac chamber, great vessel, or other structure, bypassing the myocardial capillary network. Patients with coronary artery fistulae may present with dyspnea, congestive heart failure, angina, endocarditis, arrhythmias, or myocardial infarction. Symptomatic patients must be treated in order to prevent such complications as sudden death or myocardial infarction. Surgery is the gold standard for closure of these lesions; however, an increasing number of reports have shown that percutaneous closure may be a safe and effective alternative. We report the successful percutaneous exclusion of multiple coronary artery-to-pulmonary artery fistulae by means of several balloon-expandable stent-grafts in a patient who had a history of coronary artery bypass surgery and symptoms of congestive heart failure.

Saphenous vein graft-to-left atrium fistula treated with percutaneous transcatheter embolization with coils.
(37/89)
Coronary artery fistulae are rare anomalies that are most commonly congenital and rarely acquired. We present a first case of a vein graft to the left atrium fistula that occurred post coronary artery bypass grafting and was treated with percutaneous transcatheter embolization with coiling. The coil was initially lost in the left atrium, but was successfully retrieved and the fistula was closed. We review the pertinent literature on acquired coronary artery fistulae and their management. (+info)
