Na última década, a aplicação da inteligência artificial (IA) teve avanços notáveis, em todas as áreas do conhecimento. Diversas soluções tecnológicas baseadas em IA têm sido propostas na área médica, buscando tornar o diagnóstico e o tratamento cada vez mais assertivos e seguros. O número de artigos publicados cresce vertiginosamente, e a maioria reporta estudos iniciais, provas de conceito, mas vários já têm demonstrado aplicações clínicas estruturadas. Os profissionais da saúde devem, portanto, assumir um papel de liderança na decisão de onde aplicar e como interpretar essa tecnologia. Este artigo apresenta conceitos básicos de IA, aprendizado de máquina (machine learning), aprendizado profundo ( deep learning ), redes neurais em Medicina e biomarcadores vocais.
ObjectiveTo present the results of a new experimental device developed to facilitate
the transapical access in endovascular treatment of structural heart
diseases. It aims to reduce the risk of bleeding and complications in this
type of access and demonstrate the device as a safe, fast and effective
alternative.MethodsCorPoint is composed of three parts: introducer, base with coiled spring, and
closing capsule. By rotating movements, the spring is introduced into the
myocardium and progressively approaches the base to the surface of the
heart. Guidewires and catheters are inserted through the hollow central part
and, at the end of the procedure, the capsule is screwed over the base,
therefore stopping any bleeding.ResultsThe device was implanted in 15 pigs, weighing 60 kg each, through an
anterolateral thoracotomy, while catheters were introduced and guided by
fluoroscopy. All animals had minimal bleeding; introducers with diameter up
to 22 Fr were used and various catheters and guidewires were easily handled.
After finishing the procedure, the closing capsule was attached and no
bleeding was observed at the site.ConclusionThis new device has proved effective, fast and secure for the transapical
access. This shows great potential for use, especially by ensuring an easier
and direct access to the mitral and aortic valves; the shortest distance to
be traveled by catheters; access to the ascending and descending aorta;
decreased bleeding complications; decreased surgical time; and the
possibility of allowing the technique to evolve and become totally
percutaneous.
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.
