This article assesses the complex anatomy of the atrioventricular valves in atrioventricular septal defect using bedside real-time three-dimensional echocardiography and comparing these results to the anatomic findings at the time of operative intervention. 2003-01-01T00:00:00Z Papillary fibroelastoma of the left atrium in a 3-year-old boy /library/oar/handle/123456789/4336 Title: Papillary fibroelastoma of the left atrium in a 3-year-old boy Authors: Sierig, Gabriele; Vondrys, D.; Daehnert, Ingo Abstract: A 3 year old boy presented with a cardiac murmur. Except for mildly impaired physical condition that was more likely due to asthmatic bronchitis, he was asymptomatic. Cardiac echocardiography disclosed a large tumor in the left atrium originating from the interatrial septum. The patient was immediately referred to surgery for excision of the tumor. Histological examination of the tumor showed a typical papillary fibroelastoma. The occurrence of a papillary fibroelastoma in a child is a rarity. 2003-01-01T00:00:00Z Publishing on the WWW : part 9 : video codecs and decompressors /library/oar/handle/123456789/4335 Title: Publishing on the WWW : part 9 : video codecs and decompressors Authors: Grech, Victor E. Abstract: Digital video and audio produce very large and unwieldy files. Codecs are used to shrink files and them play back in reduced file size format. This article disusses the advantages, disadvantages and tradeoffs in using codes, and briefly reviews the most commonly used codecs 2003-01-01T00:00:00Z Late presentation and successful treatment of classical scimitar syndrome /library/oar/handle/123456789/3953 Title: Late presentation and successful treatment of classical scimitar syndrome Authors: Grech, Victor E.; Xuereb, R.; Xuereb, M.; Manche, Alexander; Schembri, K.; DeGiovanni, Joseph V. Abstract: Scimitar syndrome is a form of partial anomalous pulmonary venous drainage that is dramatically visible on plain chest radiography (CXR). In these individuals the entire venous drainage from the right lung enters a single anomalous large vein that descends to the inferior vena cava. This descending vein is visible on CXR as a curvilinear density along the right heart border and resembles the curved Turkish sword that gives the condition its name. Scimitar syndrome forms part of the large spectrum of associated conditions known as venolobar syndrome. These include right lung hypoplasia or sequestered segments of right lung, congenital heart disease and various others. We report the case of a young woman who presented incidentally, with a murmur, at 16 years of age. Full investigation including angiography showed a large atrial septal defect with right heart dilation and scimitar syndrome. She underwent surgical correction with uneventful and complete correction by baffling of the scimitar vein from its entry into the inferior vena to the left atrium through the enlarged atrial septal defect. 2003-01-01T00:00:00Z
