DOMINGUEZ-DIAZ, Ángel Ernesto et al. Bicuspid aorta valve: Frequency and associated injuries. Prospective study in 2750 echocardiograms in a row. Rev. Mex. Cardiol [online]. 2013, vol.24, n.4, pp.184-188. ISSN 0188-2198.

Objective: To evaluate by a prospective, observational and cross study the incidence of bicuspid aorta valve and associated aortic disease in the echocardiography laboratory. Material and methods: We analyzed all the consecutive patients studied by echocardiography from the 1st of September 2009 to January 14, 2011, in search of bicuspid aortic bivalve and its associations. Results: A total of 2,750 studies were made in this period of time. In 72 (2.6%) was not possible to specify clearly the number of valves. There were detected 137 patients with bicuspid aortic (4.9%). The age average was 13.27 years ± 9.64, median 11 years, 81 were men (59.1%), 56 women (40.9%), 14 (10.2%) were otherwise structurally normal heart. It was found that 99 (72.3%) had aortic disease-related injuries: 50 (36.5%) had aortic coarctation, 22 (16.1%) double aortic lesion, 10 (7.3%) subaortic stenosis, 9 (6.6%) aortic stenosis, 1 (0.7%) dilation of aortic root aneurysm with aortic coarctation, 2 (1.5%) no significant expansion of the root aortic, 3 (2.2%) aortic regurgitation, 1 (0.7%) interrupted aortic arch, 1 (0.7%) developed endocarditis a in 24 cases (17.5%) with bicuspid aortic lesions were not related to aortic disease. Conclusions: The bicuspid aorta in an echocardiography lab is relatively frequent: 4.9% in this work. In patients with structurally normal heart bicuspid aorta were found in 0.5% of the population. The presence of bicuspid aorta was associated with significant injury to herself or with other lesions of the left outflow tract in 3.6% of cases. The aortic dilatation and aortic coarctation was present in 0.7% patients. The presence of bacterial endocarditis associated with bicuspid aortic found in 0.7%. It is important to the long-term monitoring of those patients with bicuspid aortic as much as 30% of cases can develop complications.
