The clinical presentation of coarctation of aorta (CoA) is well known; however, it is the most common congenital heart disease in the newborn period to be missed, with significant mortality and morbidity associated with missing the diagnosis. We report a 20-day-old newborn boy who presented with congestive heart failure and weak femoral pulses. Chest X-ray (CXR) showed cardiomegaly and pulmonar...
BACKGROUND The aorta is considered pathologically dilated if the diameters of the ascending aorta and the aortic root exceed the norms for a given age and body size. A 50% increase over the normal diameter is considered aneurysmal dilatation. Such dilatation of the ascending aorta frequently leads to significant aortic valvular insufficiency, even in the presence of an otherwise normal valve. T...
Two patients who underwent surgical exclusion of the thoracic aorta for chronic dissecting aneurysms of the descending aorta died 4 and 8 years after surgery due to complications in part related to the operative technique. One patient developed pseudoaneurysm of the proximal aortic stump with fatal exsanguination through an aortapulmonary fistula. The other patient developed progressive dilatat...
The aim of this study was to evaluate an automatic, deep learning based method (Augmented Radiology for Vascular Aneurysm [ARVA]), detect and assess maximum aortic diameter, providing cross sectional outer wall measurements. Accurate external diameter measurement is performed along the entire aorta, from ascending aorta iliac bifurcations, on both pre- post-operative contrast enhanced computed ...
BACKGROUND Ascending aortic dissection (AAD) is a rare and serious complication of aortic valve replacement. Multiple risk factors such as connective tissue disease, aortic wall thinning, aortic diameter, calcification of wall, structural features of aortic wall and associated diseases have been considered as a predisposing factor for the occurrences of AAD. Preoperative recognition of these va...
The study was carried out on 10 swine of 20-30 kg body weight. Five animals were assigned to each of 2 groups. An aneurysm of the abdominal aorta was created experimentally in animals from the first and second study group. After 4 weeks, animals from the second group were subject to aneurysm repair using an aortic prosthesis. During the experiment, we measured the myoelectric activity of the mu...
OBJECTIVE Reoperations on the ascending aorta after prior aortic procedures are formidable challenges. In order to identify factors predictive of clinical outcome using a uniform surgical approach, results of a 15-year experience were reviewed. METHODS Between 1983 and 1998, 78 reoperations on the ascending aorta were performed in 71 consecutive patients. There were 56 males and 15 females, a...
Although relatively uncommon, descending thoracic aortic aneurysms are lethal, with a natural history of progressive dilatation, rupture and death. The traditional treatment of these aneurysms involves open thoracotomy and replacement of the aneurysmal aorta with a prosthetic graft. Although successful and durable, this treatment is potentially associated with significant morbidity and mortalit...
