Un coroscanner permet d\u2019observer pr\u00e9cis\u00e9ment les art\u00e8res coronaires et certaines structures du c\u0153ur gr\u00e2ce au scanner<\/strong>. Il est principalement utilis\u00e9 pour rechercher un r\u00e9tr\u00e9cissement, une plaque d\u2019ath\u00e9rome ou une autre anomalie des art\u00e8res qui alimentent le muscle cardiaque. Cet examen est rapide, non invasif et peut compl\u00e9ter le bilan r\u00e9alis\u00e9 par le cardiologue. IMPC propose le coroscanner dans plusieurs de ses centres \u00e9quip\u00e9s d\u2019un scanner \u00e0 Paris. <\/span><\/span><\/span><\/p>\n

Pourquoi faire un coroscanner ?<\/h2>\n

Un coroscanner est r\u00e9alis\u00e9 lorsqu\u2019il est n\u00e9cessaire d\u2019examiner les art\u00e8res coronaires sans avoir recours d\u2019embl\u00e9e \u00e0 une coronarographie invasive.<\/p>\n

Les art\u00e8res coronaires assurent l\u2019apport de sang au muscle cardiaque. Lorsqu\u2019elles se r\u00e9tr\u00e9cissent en raison de d\u00e9p\u00f4ts d\u2019ath\u00e9rome, la circulation peut devenir insuffisante. Selon la situation, cela peut provoquer des douleurs thoraciques, notamment \u00e0 l\u2019effort.<\/p>\n

Le coroscanner permet alors de visualiser directement les art\u00e8res et de rechercher certaines l\u00e9sions. L\u2019Assurance Maladie indique qu\u2019un scanner coronaire avec injection peut \u00eatre demand\u00e9 pour identifier des anomalies des art\u00e8res coronaires, notamment des zones de r\u00e9tr\u00e9cissement. <\/span><\/span><\/p>\n

Il peut \u00eatre prescrit, par exemple, en cas de douleur thoracique atypique, lorsque le risque de maladie coronarienne est interm\u00e9diaire ou lorsque les autres examens ne permettent pas de conclure clairement.<\/p>\n

Que peut d\u00e9tecter un scanner coronaire ?<\/h2>\n

Le scanner coronaire peut d\u00e9tecter principalement des plaques d\u2019ath\u00e9rome et des r\u00e9tr\u00e9cissements des art\u00e8res coronaires.<\/p>\n

Gr\u00e2ce \u00e0 des images en coupe tr\u00e8s fines, le radiologue peut analyser le trajet des art\u00e8res autour du c\u0153ur et rechercher :<\/p>\n

    \n
  • des plaques calcifi\u00e9es ou non calcifi\u00e9es ;<\/li>\n
  • un r\u00e9tr\u00e9cissement d\u2019une art\u00e8re coronaire ;<\/li>\n
  • une obstruction ;<\/li>\n
  • certaines anomalies anatomiques des coronaires ;<\/li>\n
  • des anomalies pouvant n\u00e9cessiter des examens compl\u00e9mentaires.<\/li>\n<\/ul>\n

    IMPC pr\u00e9cise \u00e9galement que le coroscanner est utilis\u00e9 pour examiner les cavit\u00e9s cardiaques et aider au diagnostic pr\u00e9coce des maladies coronariennes. <\/span><\/span><\/p>\n

    Cependant, le r\u00e9sultat doit toujours \u00eatre interpr\u00e9t\u00e9 avec le contexte clinique, les sympt\u00f4mes et les autres examens cardiologiques.<\/p>\n

    Comment se d\u00e9roule un coroscanner ?<\/h2>\n

    Le coroscanner se d\u00e9roule comme un scanner classique, mais avec un protocole sp\u00e9cialement adapt\u00e9 au c\u0153ur.<\/p>\n

    Vous \u00eates install\u00e9 allong\u00e9 sur le dos sur la table du scanner. Des \u00e9lectrodes sont plac\u00e9es sur le thorax afin de synchroniser les images avec les battements cardiaques. Ensuite, une voie veineuse est g\u00e9n\u00e9ralement install\u00e9e pour injecter un produit de contraste iod\u00e9.<\/p>\n

    Pendant l\u2019acquisition, la table traverse rapidement l\u2019anneau du scanner. Il peut vous \u00eatre demand\u00e9 de retenir votre respiration quelques secondes pour \u00e9viter les mouvements.<\/p>\n

    L\u2019examen en lui-m\u00eame est tr\u00e8s rapide. La pr\u00e9paration peut toutefois prendre davantage de temps, notamment si l\u2019\u00e9quipe doit v\u00e9rifier votre fr\u00e9quence cardiaque avant de r\u00e9aliser les images.<\/p>\n

    Dans certains cas, un m\u00e9dicament peut \u00eatre utilis\u00e9 pour ralentir l\u00e9g\u00e8rement le rythme du c\u0153ur afin d\u2019am\u00e9liorer la nettet\u00e9 des images. Cette d\u00e9cision d\u00e9pend du protocole m\u00e9dical.<\/p>\n

    Pourquoi utilise-t-on un produit de contraste ?<\/h2>\n

    Le produit de contraste permet de rendre les art\u00e8res coronaires beaucoup plus visibles sur les images.<\/p>\n

    Il est g\u00e9n\u00e9ralement inject\u00e9 dans une veine du bras juste avant l\u2019acquisition. Gr\u00e2ce \u00e0 l\u2019iode qu\u2019il contient, le sang circulant dans les art\u00e8res appara\u00eet clairement sur le scanner.<\/p>\n

    Cela permet au radiologue d\u2019examiner la lumi\u00e8re des vaisseaux et de rechercher un \u00e9ventuel r\u00e9tr\u00e9cissement.<\/p>\n

    Au moment de l\u2019injection, certaines personnes ressentent bri\u00e8vement une sensation de chaleur dans le corps ou un go\u00fbt inhabituel dans la bouche. Ces sensations disparaissent g\u00e9n\u00e9ralement rapidement.<\/p>\n

    Avant l\u2019examen, il est donc important de signaler une maladie r\u00e9nale, une r\u00e9action ant\u00e9rieure \u00e0 un produit de contraste ou certaines allergies connues.<\/p>\n

    Comment se pr\u00e9parer \u00e0 un coroscanner ?<\/span><\/h2>\n

    La pr\u00e9paration vise surtout \u00e0 obtenir un rythme cardiaque suffisamment stable et des images pr\u00e9cises.<\/p>\n

    Les consignes peuvent varier selon le centre et votre situation m\u00e9dicale. Il peut notamment \u00eatre recommand\u00e9 d\u2019\u00e9viter certains excitants avant l\u2019examen.<\/p>\n

    L\u2019Assurance Maladie mentionne, dans certains examens cardiovasculaires, des pr\u00e9cautions concernant la caf\u00e9ine avant l\u2019exploration. Les instructions exactes d\u00e9pendent toutefois du protocole choisi par l\u2019\u00e9quipe m\u00e9dicale. <\/span><\/span><\/p>\n

    Avant le rendez-vous, pensez \u00e9galement \u00e0 signaler :<\/p>\n

      \n
    • une grossesse connue ou possible ;<\/li>\n
    • une insuffisance r\u00e9nale ;<\/li>\n
    • une allergie ou r\u00e9action ant\u00e9rieure \u00e0 un produit iod\u00e9 ;<\/li>\n
    • vos traitements cardiovasculaires ;<\/li>\n
    • un asthme ou une autre pathologie importante.<\/li>\n<\/ul>\n

      Enfin, apportez votre ordonnance et les anciens examens du c\u0153ur ou des art\u00e8res coronaires si vous en disposez.<\/p>\n

      Quelle est la diff\u00e9rence entre coroscanner et coronarographie ?<\/h2>\n

      Le coroscanner est un examen non invasif, tandis que la coronarographie n\u00e9cessite l\u2019introduction d\u2019un cath\u00e9ter dans une art\u00e8re.<\/p>\n

      Lors d\u2019un coroscanner, les images sont obtenues gr\u00e2ce aux rayons X et \u00e0 l\u2019injection d\u2019un produit iod\u00e9 dans une veine. Il n\u2019est donc pas n\u00e9cessaire d\u2019introduire un cath\u00e9ter jusqu\u2019au c\u0153ur.<\/p>\n

      La coronarographie, elle, permet d\u2019examiner directement les art\u00e8res coronaires gr\u00e2ce \u00e0 un cath\u00e9ter introduit le plus souvent par une art\u00e8re du poignet ou de l\u2019aine.

      Ainsi, le coroscanner est surtout un outil diagnostique. Selon les r\u00e9sultats, une coronarographie peut ensuite \u00eatre n\u00e9cessaire si une l\u00e9sion importante est suspect\u00e9e. L\u2019Assurance Maladie distingue bien ces deux examens dans le bilan des maladies coronariennes. <\/span><\/span><\/p>[\/et_pb_text][\/et_pb_column][et_pb_column type=\u00a0\u00bb2_5″ _builder_version=\u00a0\u00bb4.16″ _module_preset=\u00a0\u00bbdefault\u00a0\u00bb custom_padding=\u00a0\u00bb80px|||\u00a0\u00bb global_colors_info=\u00a0\u00bb{}\u00a0\u00bb custom_padding__hover=\u00a0\u00bb|||\u00a0\u00bb][et_pb_blurb title=\u00a0\u00bbRDV \u00e9chographie en ligne sur Doctolib\u00a0\u00bb use_icon=\u00a0\u00bbon\u00a0\u00bb font_icon=\u00a0\u00bb\ue023||divi||400″ icon_color=\u00a0\u00bb#282828″ icon_placement=\u00a0\u00bbleft\u00a0\u00bb image_icon_width=\u00a0\u00bb70px\u00a0\u00bb content_max_width=\u00a0\u00bb105%\u00a0\u00bb icon_placement_tablet=\u00a0\u00bbleft\u00a0\u00bb icon_placement_phone=\u00a0\u00bbleft\u00a0\u00bb icon_placement_last_edited=\u00a0\u00bbon|phone\u00a0\u00bb image_icon_width_tablet=\u00a0\u00bb70px\u00a0\u00bb image_icon_width_phone=\u00a0\u00bb35px\u00a0\u00bb image_icon_width_last_edited=\u00a0\u00bbon|phone\u00a0\u00bb _builder_version=\u00a0\u00bb4.27.4″ _module_preset=\u00a0\u00bbdefault\u00a0\u00bb header_level=\u00a0\u00bbh2″ header_font=\u00a0\u00bb–et_global_heading_font|700||on|||||\u00a0\u00bb header_text_align=\u00a0\u00bbleft\u00a0\u00bb header_text_color=\u00a0\u00bb#282828″ header_font_size=\u00a0\u00bb24px\u00a0\u00bb body_font=\u00a0\u00bb–et_global_body_font||||||||\u00a0\u00bb body_text_color=\u00a0\u00bb#424242″ body_font_size=\u00a0\u00bb17px\u00a0\u00bb body_line_height=\u00a0\u00bb1.6em\u00a0\u00bb background_color=\u00a0\u00bbRGBA(255,255,255,0)\u00a0\u00bb image_icon_custom_margin=\u00a0\u00bb-10px||||false|false\u00a0\u00bb image_icon_custom_margin_tablet=\u00a0\u00bb-10px||||false|false\u00a0\u00bb image_icon_custom_margin_phone=\u00a0\u00bb-10px||||false|false\u00a0\u00bb image_icon_custom_margin_last_edited=\u00a0\u00bbon|desktop\u00a0\u00bb width=\u00a0\u00bb100%\u00a0\u00bb width_tablet=\u00a0\u00bb89%\u00a0\u00bb width_phone=\u00a0\u00bb100%\u00a0\u00bb width_last_edited=\u00a0\u00bbon|tablet\u00a0\u00bb module_alignment=\u00a0\u00bbcenter\u00a0\u00bb custom_margin=\u00a0\u00bb0px||35px|0px|false|false\u00a0\u00bb custom_margin_tablet=\u00a0\u00bb-16px||0px||false|false\u00a0\u00bb custom_margin_phone=\u00a0\u00bb0px||0px|0px|false|false\u00a0\u00bb custom_margin_last_edited=\u00a0\u00bbon|desktop\u00a0\u00bb custom_padding=\u00a0\u00bb0px||0px|3px|true|false\u00a0\u00bb custom_padding_tablet=\u00a0\u00bb40px||40px|39px|true|false\u00a0\u00bb custom_padding_phone=\u00a0\u00bb17px||17px|0px|true|false\u00a0\u00bb custom_padding_last_edited=\u00a0\u00bbon|phone\u00a0\u00bb header_text_align_tablet=\u00a0\u00bbleft\u00a0\u00bb header_text_align_phone=\u00a0\u00bbleft\u00a0\u00bb header_text_align_last_edited=\u00a0\u00bbon|phone\u00a0\u00bb header_font_size_tablet=\u00a0\u00bb24px\u00a0\u00bb header_font_size_phone=\u00a0\u00bb18px\u00a0\u00bb header_font_size_last_edited=\u00a0\u00bbon|phone\u00a0\u00bb body_font_size_tablet=\u00a0\u00bb17px\u00a0\u00bb body_font_size_phone=\u00a0\u00bb12px\u00a0\u00bb body_font_size_last_edited=\u00a0\u00bbon|phone\u00a0\u00bb border_width_all_image=\u00a0\u00bb0px\u00a0\u00bb locked=\u00a0\u00bboff\u00a0\u00bb global_colors_info=\u00a0\u00bb{}\u00a0\u00bb]

      Coroscanner et score calcique : quelle diff\u00e9rence ?<\/h2>\n

      Le coroscanner et le score calcique utilisent tous deux le scanner, mais ils ne r\u00e9pondent pas exactement \u00e0 la m\u00eame question.<\/p>\n

      Le score calcique<\/strong> mesure principalement la quantit\u00e9 de calcium pr\u00e9sente dans les art\u00e8res coronaires. Il peut \u00eatre utilis\u00e9 pour mieux estimer le risque cardiovasculaire dans certaines situations.<\/p>\n

      Le coroscanner<\/strong>, quant \u00e0 lui, permet d\u2019\u00e9tudier plus directement l\u2019anatomie des art\u00e8res et leur lumi\u00e8re, g\u00e9n\u00e9ralement gr\u00e2ce \u00e0 une injection de contraste.<\/p>\n

      Ainsi, un patient peut parfois b\u00e9n\u00e9ficier d\u2019un score calcique seul, d\u2019un coroscanner ou des deux selon l\u2019objectif du bilan cardiovasculaire.<\/p>\n

      Le coroscanner pr\u00e9sente-t-il des risques ?<\/h2>\n

      Le coroscanner utilise des rayons X et entra\u00eene donc une exposition aux rayonnements ionisants. Cependant, les protocoles modernes visent \u00e0 utiliser la dose la plus faible compatible avec des images de bonne qualit\u00e9.<\/p>\n

      IMPC indique notamment utiliser des scanners multi-barrettes de derni\u00e8re g\u00e9n\u00e9ration afin d\u2019am\u00e9liorer la qualit\u00e9 des images et de r\u00e9duire l\u2019exposition. <\/span><\/span><\/p>\n

      L\u2019autre pr\u00e9caution concerne le produit de contraste iod\u00e9. Les r\u00e9actions importantes sont rares, mais une attention particuli\u00e8re est n\u00e9cessaire en cas d\u2019insuffisance r\u00e9nale ou d\u2019ant\u00e9c\u00e9dent de r\u00e9action apr\u00e8s injection.<\/p>\n

      Enfin, en cas de grossesse, l\u2019examen doit \u00eatre discut\u00e9 avec le m\u00e9decin en raison de l\u2019utilisation de rayons X.<\/p>\n

      Combien de temps dure un coroscanner ?<\/h2>\n

      Le temps d\u2019acquisition des images est tr\u00e8s court, mais le rendez-vous complet peut durer plus longtemps en raison de la pr\u00e9paration.<\/p>\n

      Il faut notamment pr\u00e9voir le temps n\u00e9cessaire \u00e0 l\u2019installation, \u00e0 la pose de la voie veineuse et au contr\u00f4le de la fr\u00e9quence cardiaque. Selon votre rythme cardiaque, l\u2019\u00e9quipe peut \u00e9galement attendre quelques minutes avant de r\u00e9aliser l\u2019acquisition.<\/p>\n

      Ainsi, il est pr\u00e9f\u00e9rable de pr\u00e9voir une marge suffisante plut\u00f4t que de se baser uniquement sur les quelques secondes n\u00e9cessaires au scanner lui-m\u00eame.<\/p>\n

      Apr\u00e8s l\u2019examen, vous pouvez g\u00e9n\u00e9ralement reprendre vos activit\u00e9s habituelles, sauf consigne particuli\u00e8re de l\u2019\u00e9quipe m\u00e9dicale.<\/p>\n

      Confort et accompagnement pendant le scanner cardiaque<\/h2>\n

      Le coroscanner est rapide et g\u00e9n\u00e9ralement indolore. La principale sensation inhabituelle survient souvent lors de l\u2019injection du produit de contraste.<\/p>\n

      Avant l\u2019examen, l\u2019\u00e9quipe explique chaque \u00e9tape et r\u00e9pond \u00e0 vos questions. Si vous \u00eates anxieux, avez d\u00e9j\u00e0 mal tol\u00e9r\u00e9 une injection ou pr\u00e9sentez une difficult\u00e9 particuli\u00e8re, signalez-le d\u00e8s votre arriv\u00e9e.<\/p>\n
