Abstract

montagem de válvula cardíaca que tem uma estrutura que compreende uma seção de ancoragem, uma seção de sustentação de prolapso, em geral, cilíndrica, e uma seção de gargalo que muda entre a seção de ancoragem e a seção de sustentação da válvula. a seção de ancoragem tem uma configuração em formato de esfera definida por uma pluralidade de fios que se estendem a partir da seção de sustentação de prolapso, em que cada fio se estende radialmente para fora para uma área de vértice em que o diâmetro da seção de ancoragem está em seu máximo e, então, se estende radialmente para dentro para um cubo. uma pluralidade de prolapsos são suturados à seção de sustentação de prolapso. a montagem de válvula cardíaca é entregue para a localização de um tronco pulmonar nativo, a área de vértice da seção de ancoragem é instalada nas artérias pulmonares nativas de modo que a área de vértice seja retida nas artérias pulmonares e, então, a seção de sustentação de prolapso é instalada no tronco pulmonar.
