D\u00e9finition<\/h1>\n

La st\u00e9nose valvulaire pulmonaire est un \u00e9tat dans lequel une d\u00e9formation sur ou pr\u00e8s de la valve pulmonaire ralentit le flux sanguin.\u00a0 <\/span>La valve pulmonaire aide \u00e0 diriger le flux sanguin du c\u0153ur vers les poumons et la st\u00e9nose (ou r\u00e9tr\u00e9cissement) survient lorsque les valves sont incapables de s’ouvrir assez largement. Par cons\u00e9quent, le flux sanguin vers les poumons est r\u00e9duit.<\/span><\/p>\n

Dans la plupart des cas, la st\u00e9nose valvulaire pulmonaire est une complication d’une autre maladie ; cependant, elle est plus fr\u00e9quente avant la naissance en tant que malformation cardiaque cong\u00e9nitale.<\/span><\/p>\n

Les options de traitement de la st\u00e9nose pulmonaire impliquent g\u00e9n\u00e9ralement une intervention chirurgicale. La plupart des personnes qui subissent une intervention chirurgicale peuvent s’attendre \u00e0 des issues positives, sans complications ou r\u00e9cidives suppl\u00e9mentaires.<\/span><\/p>\n

\u00a0<\/span><\/span><\/p>\n

Sympt\u00f4mes<\/span><\/h2>\n

Les signes et sympt\u00f4mes de st\u00e9nose valvulaire pulmonaire varient selon l’\u00e9tat de sant\u00e9 g\u00e9n\u00e9ral d’une personne et l’\u00e9tendue de l’obstruction dans son corps.<\/span><\/p>\n

\u00a0<\/span><\/span><\/p>\n

Causes<\/span><\/h2>\n

Dans la plupart des cas, la st\u00e9nose valvulaire pulmonaire est pr\u00e9sente \u00e0 la naissance. Si la valvule pulmonaire ne se d\u00e9veloppe pas correctement pendant le d\u00e9veloppement du f\u0153tus, elle peut restreindre la circulation sanguine et le nourrisson peut finir par d\u00e9velopper des anomalies cardiaques.\u00a0 <\/span><\/span><\/p>\n

Parfois, d’autres conditions m\u00e9dicales peuvent causer une st\u00e9nose valvulaire pulmonaire, telles que :<\/span><\/p>\n

Syndrome carcino\u00efde : ensemble de sympt\u00f4mes caus\u00e9s par des tumeurs carcino\u00efdes, qui se d\u00e9veloppent \u00e0 partir des cellules qui font partie du syst\u00e8me endocrinien. Elles lib\u00e8rent une substance chimique appel\u00e9e s\u00e9rotonine, qui peut provoquer les sympt\u00f4mes d’une tumeur carcino\u00efde (rougeurs de la peau, diarrh\u00e9e, crampes d’estomac).<\/span><\/p>\n

Fi\u00e8vre rhumatismale :\u00a0 <\/span>maladie qui peut r\u00e9sulter de complications dues \u00e0 un traitement inad\u00e9quat de la pharyngite streptococcique ou de la scarlatine.<\/span><\/p>\n

\u00a0<\/span><\/span><\/p>\n

Facteurs de risque<\/span><\/h2>\n

Certains troubmes qui peuvent augmenter le risque de d\u00e9velopper une st\u00e9nose valvulaire pulmonaire plus tard dans la vie comprennent notamment les suivants :<\/span><\/p>\n

\u00b7\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 <\/span><\/span><\/span>Syndrome carcino\u00efde<\/span><\/p>\n

\u00a0<\/span><\/span><\/p>\n

Complications<\/span><\/h2>\n

Les complications qui peuvent survenir dans les cas graves de st\u00e9nose pulmonaire peuvent notamment inclure :<\/span><\/p>\n

\u00b7\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 <\/span><\/span><\/span>Endocardite infectieuse : infections bact\u00e9riennes dans la paroi interne du c\u0153ur<\/span><\/p>\n

Cette pression fait durcir la paroi musculaire du ventricule et agrandir la chambre \u00e0 l’int\u00e9rieur du ventricule. \u00c9ventuellement, le c\u0153ur se raidit et peut s’affaiblir.<\/span><\/p>\n

\u00b7\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 <\/span><\/span><\/span>Arythmie : rythme cardiaque irr\u00e9gulier (battements du c\u0153ur trop rapides ou trop lents).<\/span><\/p>\n

\u00a0<\/span><\/span><\/p>\n

Traitement<\/span><\/h2>\n

Selon le degr\u00e9 d’obstruction, les options de traitement de la st\u00e9nose pulmonaire grave comprennent g\u00e9n\u00e9ralement une valvuloplastie par ballonnet ou une chirurgie \u00e0 c\u0153ur ouvert.<\/span><\/p>\n

Valvuloplastie par ballonnet : proc\u00e9dure qui consiste \u00e0 \u00e9largir une valvule cardiaque qui est r\u00e9tr\u00e9cie. Par l’insertion d’un petit tube dans une veine de la jambe jusqu’au c\u0153ur, un ballon non gonfl\u00e9 est plac\u00e9 par l’ouverture de la valve pulmonaire r\u00e9tr\u00e9cie. En gonflant le ballon, la valvule r\u00e9tr\u00e9cie s’\u00e9largit et le d\u00e9bit sanguin est augment\u00e9. Les effets secondaires possibles peuvent comprendre des saignements, des caillots sanguins ou une infection.<\/span><\/p>\n

Chirurgie \u00e0 c\u0153ur ouvert : intervention chirurgicale qui consiste \u00e0 r\u00e9parer l’art\u00e8re ou la valve pulmonaire ou \u00e0 remplacer la valve originale par une valve artificielle. Les effets secondaires possibles peuvent comprendre des saignements, des caillots sanguins ou une infection.<\/span><\/p>\n","protected":false},"featured_media":0,"template":"","class_list":["post-72538","disease","type-disease","status-publish","hentry"],"yoast_head":"\nSt\u00e9nose valvulaire pulmonaire - Humanitas.net<\/title>\n<meta name=\"robots\" content=\"noindex, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<meta property=\"og:locale\" content=\"fr_FR\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"St\u00e9nose valvulaire pulmonaire - Humanitas.net\" \/>\n<meta property=\"og:description\" content=\"D\u00e9finition La st\u00e9nose valvulaire pulmonaire est un \u00e9tat dans lequel une d\u00e9formation sur ou pr\u00e8s de la valve pulmonaire ralentit le flux sanguin.\u00a0 La valve pulmonaire aide \u00e0 diriger le flux sanguin du c\u0153ur vers les poumons et la st\u00e9nose (ou r\u00e9tr\u00e9cissement) survient lorsque les valves sont incapables de s’ouvrir assez largement.
