Abstract

"BIOPRóTESE DE VáLVULA CARDìACA SEM STENT, E, PROCESSOS PARA SUBSTITUIçãO TOTAL DE RAIZ DE UMA VáLVULA CARDìACA AóRTICA ENDóGENA NUM PACIENTE MAMìFERO, E PARA SUBSTITUIçãO CIRúRGICA DE UMA VáLVULA CARDìACA E UM SEGMENTO DE TECIDO VASCULAR ADJACENTE NUM PACIENTE MAMìFERO". Trata-se de uma bioprótese aórtica sem "stent" (desprovida de estrutura inibidora de estenose) possuindo segmentos arteriais coronários sem ligamentos e desobstruídos, estendendo-se a partir da mesma, e processos para substituição cirúrgica de válvulas cardíacas aórticas e/ou não aórticas (por exemplo, pulmonares) utilizando a referida bioprótese aórtica sem "stent". A presença dos segmentos coronários desobstruídos e desprovidos de ligamentos facilita a anastomose de extremidade a extremidade das artérias coronárias nativas do paciente e/ou de enxertos de bypass arteriais coronários existentes aos segmentos coronários da bioprótese mesmo quando essas artérias coronárias nativas (ou enxertos coronários) são excessivamente curtas ou curtos para alcançarem a parede do segmento aórtico da bioprótese. A presença desses segmentos coronários desobstruídos e desprovidos de ligamentos elimina igualmente a necessidade de remoção de um "botão" ou segmentos da aorta nativa relativamente aos segmentos arteriais coronários nativos anteriormente à implantação da bioprótese, sendo assim vantajosa para pacientes cuja aorta ascendente se encontra doente ou de outra forma comprometida.
