Environ <\/span>800 000 canadiens <\/b><\/span>souffrent de maladies valvulaires cardiaques. Elles causent environ <\/span>25 000 d\u00e9c\u00e8s<\/b><\/span> chaque ann\u00e9e en <\/span>Am\u00e9rique du Nord<\/b><\/span>. Malgr\u00e9 cela, les m\u00e9canismes impliqu\u00e9s dans le d\u00e9veloppement et la progression des maladies valvulaires ne sont pas bien \u00e9lucid\u00e9s. \u00c0 ce jour, il existe aucun traitement m\u00e9dical permettant de ralentir ou d’arr\u00eater leur progression.<\/span><\/p>\n

                                <\/span>Les t<\/b>ypes de maladies valvulaires<\/strong><\/span><\/p>\n

On parle d’insuffisance valvulaire lorsque la valve n’est pas compl\u00e8tement \u00e9tanche et que survient une <\/span>r\u00e9gurgitation <\/span>(fuite) de sang. D’autre part quand la valve ne s’ouvre pas compl\u00e8tement on parle de <\/span>s<\/span>t\u00e9nose valvulaire<\/span>. La st\u00e9nose ou la r\u00e9gurgitation (ou les deux combin\u00e9es) peuvent toucher les quatre valves du coeur mais les <\/span>valves aortiques<\/span> et <\/span>mitra<\/span>les sont les plus souvent affect\u00e9es.<\/span><\/p>\n

La st\u00e9nose aortique, est la maladie valvulaire cardiaque la plus courante dans les pays \u00e0 haut revenu. Cette maladie \u00e9volue lentement et conduit \u00e0 l\u2019obstruction de l’\u00e9coulement naturel du sang \u00e0 travers la valve aortique du c\u0153ur. Quand le patient manifeste une st\u00e9nose aortique s\u00e9v\u00e8re, le seul <\/span>traitement efficace<\/span> consiste \u00e0 <\/span>remplac<\/span>er <\/span>la valve aortique<\/span> atteinte par une proth\u00e8se soit m\u00e9canique ou biologique.<\/span> Il est crucial d’intervenir au bon moment au cours de la maladie (ni trop t\u00f4t, ni trop tard) et d\u2019utiliser la proth\u00e8se valvulaire qui est la plus adapt\u00e9e \u00e0 la situation de chaque patient. <\/span><\/p>\n

Le<\/span> <\/span>Dr Pibarot et son \u00e9quipe<\/span> ont propos\u00e9 et valid\u00e9 de <\/span>nouvelles m\u00e9thodes <\/span>afin de d\u00e9terminer le moment optimal pour remplacer la valve d\u00e9faillante et choisir la proth\u00e8se valvulaire la plus appropri\u00e9e pour le patient. <\/span>Ces m\u00e9thodes sont d\u00e9sormais utilis\u00e9es dans de nombreux h\u00f4pitaux \u00e0 travers le monde<\/span>. <\/span><\/p>\n

Pour remplacer la valve aortique d\u00e9faillante, il existe deux types d’interventions : <\/span><\/p>\n

– S<\/span>i le patient a un <\/span>faible<\/span> risque chirurgical<\/span>:<\/span> en g\u00e9n\u00e9ral, la chirurgie \u00e0 c\u0153ur ouvert est prioris\u00e9e. Cependant cette op\u00e9ration n’est pas adapt\u00e9e \u00e0 tous les patients.<\/span><\/p>\n

–  Si le patient est trop fragile pour avoir recours \u00e0 un remplacement chirurgical de la valve aortique, <\/span>on va le plus souvent opter pour<\/span> une <\/span>te<\/span>chnique r\u00e9volutionnaire<\/span> peu invasive <\/span>: l\u2019implantation d’une proth\u00e8se valvulaire percutan\u00e9e (TAVI)<\/span>.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t
