The use of extracorporeal circulation and deep circulatory arrest provide an optimal technique for removing the tumor thrombus in a bloodless field, even in the presence of metastatic disease, and has good early and long-term results.
Patients with long-standing AF and rheumatic heart disease have a very high prevalence of atrial amyloidosis. Amyloid deposition is more frequent in left than in right atrial appendage and correlates with AF duration and female gender. Amyloid deposition could constitute an additional histological feature in the structural remodeling of atria during long-standing AF, at least in rheumatic valve disease. Persistence of AF might play a pivotal role in promoting amyloid deposition.
scite is a Brooklyn-based startup 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.
