Abstract
La divulgation concerne des technologies de gestion de pression élevée de remplissage côté gauche visant à atténuer les effets d'un" dysfonction diastolique. Des modes de réalisation concernent des moyens permettant de réduire l'augmentation dans le temps du flux et de la pression du sang venant du système veineux dans le cœur. En effet, il existe un déplacement du sang du réservoir du système vasculaire "sans contrainte", qui comprend principalement le système splanchnique, au réservoir "avec contrainte", qui comprend le cœur et les poumons. Au moyen de l'inhibition de ce déplacement brusque du sang du réservoir "sans contrainte" au réservoir "avec contrainte", un afflux indésirable de volume sanguin vers le côté gauche du cœur, déjà surchargé, peut être évité. Certains modes de réalisation concernent des manières d'augmenter l'élasticité atriale ou la conformité atriale. L'amélioration de la conformité atriale permet à l'atrium "d'absorber" l'énergie de salves courtes de pression élevée dans l'atrium gauche. Ceci résulte en une réduction du flux rétrograde dans les veines pulmonaires, permettant d'inhiber une congestion pulmonaire aiguë.
