1/6. Anomalous origin of a posterior descending artery from the right pulmonary artery: report of a rare case diagnosed by multidetector computed tomography angiography.The case of a mildly symptomatic 43-year-old man with evidence of reversible inferior wall ischemia by radioisotope stress testing is described. Invasive catheterization showed abnormal connections between the coronary arteries and the pulmonary circulation. multidetector computed tomography elucidated the previously undescribed finding of a posterior descending artery originating from the right pulmonary artery.- - - - - - - - - - ranking = 1keywords = circulation (Clic here for more details about this article) |
2/6. Endovascular treatment of a coronary artery bypass graft to pulmonary artery fistula with coil embolization.Fistula formation between a coronary artery bypass graft (CABG)and the pulmonary arterial circulation represents a rare cause of recurrent angina in patients following bypass grafting. Therapy has traditionally involved surgical ligation by open thoracotomy. We describe a case of left internal mammary artery-left upper lobe pulmonary artery fistula presenting as early recurrent angina following CABG. The fistula was embolized using platinum coils, resulting in symptomatic relief and improvement in myocardial perfusion on cardiac perfusion scintigraphy. Coil embolization should be considered a therapeutic option in patients with coronary-pulmonary steal syndrome.- - - - - - - - - - ranking = 1keywords = circulation (Clic here for more details about this article) |
3/6. Coronary artery fistula as source of pulmonary circulation in pulmonary atresia with ventricular septal defect.Four patients are described with pulmonary atresia and ventricular septal defect, in whom the pulmonary circulation was dependent on a fistula from the left coronary artery to the pulmonary artery. The issue in this complex anomaly is complete preoperative diagnosis, including anatomic information on the coronary artery fistula and the pulmonary vasculature. This was achieved in the last 2 patients. In the last patient echocardiography turned out to be an important diagnostic tool in this rare anomaly and facilitated selective angiocardiography. All 4 patients were successfully operated by closing the fistula, closing other aortopulmonary connections and inserting a valved conduit between right ventricle and pulmonary artery. The ventricular septal defect was closed in 3 patients with a patch. In the setting of an already existing pulmonary hypertension and a possibly inadequate pulmonary arterial system at surgery, a perforated patch was inserted in the ventricular septal defect of the remaining patient.- - - - - - - - - - ranking = 5keywords = circulation (Clic here for more details about this article) |
4/6. Broncho-oesophageal fistula with vascular malformation.We present a patient with a type III congenital broncho-oesophageal fistula and a connection between the systemic and the pulmonary circulation. The congenital fistula caused chronic bronchopulmonary suppuration with bronchiectasis which in turn was the cause of a left-to-right shunt, probably through multiple precapillary or capillary anastomoses.- - - - - - - - - - ranking = 1keywords = circulation (Clic here for more details about this article) |
5/6. Internal mammary artery to pulmonary artery fistula.A rare case of arteriovenous fistula between an internal mammary artery and a pulmonary artery is presented. The clinical history of recurrent bronchitis and dyspnoea during exercise, the presence of right parasternal murmur with normal heart size and normal blood gases justified the execution of an arteriovenous thoracic angiography which revealed the presence of a cirsoid aneurysm supplied by the internal and external mammary arteries. Diagnostic investigation and surgical indication in patients with the rare fistulous communication between the internal mammary artery and the systemic or pulmonary circulation are analysed.- - - - - - - - - - ranking = 1keywords = circulation (Clic here for more details about this article) |
6/6. pulmonary atresia and ventricular septal defect with coronary artery to pulmonary artery fistula: case report and review of the literature.The pulmonary blood supply in patients with pulmonary atresia and ventricular septal defect is highly variable. Several cases have been reported in the literature in which a coronary artery to pulmonary artery fistula, alone or in combination with additional vessels, supplies the pulmonary circulation. We report a case of successful repair during early infancy, with unique hemodynamic, clinical, and anatomic features. The literature is reviewed.- - - - - - - - - - ranking = 1keywords = circulation (Clic here for more details about this article) |
