Stent misdeployment was constant in bicuspid valves and occurred in one-third of cases of tricuspid valves. Premature failure of implanted VS (secondary to valve distortion or traumatic injury to the leaflets by calcific excrescences) might be an important concern in the future.
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.
In case of late posterior failure of mitral valve repair for severe degenerative, re-repair is feasible in about 70% of the patients with encouraging results at 10 years.
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.
