Transesophageal echocardiography (TEE) imaging of the aorta requires multiple views and is limited by its inability to visualize the distal ascending aorta and proximal aortic arch ("blind spot"). Recent advances in ultrasound technology allow improved imaging of cardiac structures. In this study we describe the ability to image the aortic valve, entire ascending aorta, and aortic arch in one view, the "expanded aortic view" obtained from a novel proximal transgastric window. In 22 patients, an expanded aortic view was acquired with the transducer positioned in a proximal transgastric position using new generation ultrasound system with a TEE probe that incorporates increased range of mobility. Fluoroscopy imaging was performed to confirm the position of transducer in relation to the cardiac anatomy. In 7 of 22 patients, the ability to achieve this view was also tested using an older echocardiography system. The novel proximal transgastric plane allowed reliable images of the aortic valve, ascending aorta including the "blind spot," and aortic arch in a single view-the expanded aortic view. 相似文献

In this report 5 patients between the ages of 5-14 years admitted to the Department of Pediatric Cardiology, Hacettepe University, and diagnosed as having pseudocoarctation of the aorta are presented. The clinical and angiographic findings of this rare abnormality of childhood are discussed, the importance of differential diagnosis of this entity from coarctation of the aorta is emphasized, and the literature reviewed. 相似文献

After resection of the coarctation in a 3-year-old child with end-to-end anastomosis, a second membrane was found 1.5 cm lower. After a successful reoperation with an aortoplasty using Gore-Tex weak femoral pulses persisted. At catheterization, an area of irregular narrowing of the abdominal aorta just distal to the superior mesenteric artery was found with hypoplasia of the iliac and femoral arteries. In addition, this child had a two-sided cheilo-gnatho-palatoschisis, vesicoureteral reflux and absence of gall bladder and hepato-duodenal ligament. It is worthwhile considering that a second or third aortic abnormality can be hidden by a coarctation of the aorta. 相似文献

Primary aortic tumors are extremely rare. A 73-year-old woman presented with a 8 kg weight loss associated with abdominal pain. Physical examination was normal. Laboratory tests disclosed increased acute phase reactants. Thoracic and abdominal CT scan showed diffuse splenic and renal hypodense lesions with thrombotic feature of the thoracic aorta extending on 9 cm length. Transesophageal echocardiography showed a large and heterogeneous floating mass advocating a thrombus developed on atheroma. Because of the high risk of embolism the patient underwent surgical replacement of the thoracic aorta. Histopathology revealed an epithelioid angiosarcoma of the aorta. A primary tumor of the aorta should be suspected in the presence of an intra-aortic process presenting features of thrombosis. 相似文献
