Transcatheter aortic valve implantation was developed to offer a therapeutic solution to patients with severe symptomatic aortic stenosis who are not candidates for conventional aortic valve replacement. The improvement in transcatheter aortic valve implantation outcomes is still of concern in the areas of stroke, vascular injury, heart block, paravalvular regurgitation and valve durability. Concomitantly, the progress, both technical and in terms of material advances of transcatheter valve systems, as well as in patient selection, renders transcatheter aortic valve implantation an increasingly viable treatment for more and more patients with structural heart disease.
Cardiac injuries after penetrating chest trauma are uncommon but potentially life threatening; these injuries can remain occult during the early stage because of the cardiac reserve of youthful physiology and may present at a later stage as the initial damage progresses or compensatory mechanisms fail. We report a case of unusual penetrating cardiac trauma from a posterior intercostal stab wound that affected both the interatrial septum and the tricuspid valve, leading to a stormy presentation as a result of the development of an acute right-to-left shunt followed by a successful surgical repair.
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.
