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 /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 /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
