External aortic ring annuloplasty provides a reproducible technique for aortic valve repair with satisfactory long-term results for each ascending aorta phenotype with bicuspid or tricuspid valve. Longer follow-up is ongoing with the AVIATOR registry.
Atrial septal aneurysm is an uncommon condition. Between 1981 and 1984 10 cases of atrial septal aneurysm were diagnosed by real time cross sectional echocardiography performed in 4840 patients. The aneurysm was associated either with mitral valve prolapse (three patients) or with atrial septal defect (three patients) or occurred in isolation (four patients, two of whom had had a previous embolic event leading to the diagnosis of atrial septal aneurysm by cross sectional echocardiography). During cross sectional echocardiography the aneurysm appeared as a localised bulging of the interatrial septum, which was best seen in the subcostal four chamber view and in the parasternal short axis view at the level of the aortic root. The aneurysm either protruded into only the right atrium (five patients) or moved backwards and forwards between the right and the left atria during the cardiac cycle (five patients). This motion pattern might be related to changes in the interatrial pressure gradient. The two patients who had had a systemic embolism were given anticoagulant treatment, but none underwent surgery.It is concluded that the true prevalence of atrial septal aneurysm might have been underestimated before the routine use of cross sectional echocardiography, that cross sectional echocardiography enables definitive diagnosis of this condition by a non-invasive technique, and that an atrial septal aneurysm should be suspected and looked for by cross sectional echocardiography after an unexplained systemic embolism.Atrial septal aneurysm is a localised deformity of the interatrial septum which protrudes into the right or the left atrium or both. I It might result from bulging of septum primum tissue through the fossa ovalis.2 This lesion, which is uncommon, is often unrecognised in asymptomatic subjects.34 Serious complications such as embolic phenomena may, however, occur.9 Cross sectional echocardiography is a noninvasive technique that allows these aneurysms to be diagnosed definitively. With the exception of 11 cases reported by Hauser et al,10 cross sectional echocardiography has been undertaken in only single or a few Requests for reprints to
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
