Abstract
(EN)
The present disclosure relates to a method and apparatus for coronary stenosis assessment, a storage medium, and an electronic device. The method comprises: obtaining an angiographic image of a coronary artery; performing vessel three-dimensional reconstruction according to the angiographic image to obtain a three-dimensional vessel model of the coronary artery; for a target branch of the coronary artery, performing a pressure drop test on the three-dimensional vessel model to obtain a quadratic function relationship between a blood flow rate and a blood flow pressure of the target branch, the target branch being any branch of the coronary artery; and assessing a stenosis condition of the coronary artery according to a constant coefficient of the quadratic function relationship. Embodiments of the present disclosure are used for assessing the stenosis degree of a vessel.

La présente invention concerne un procédé et un appareil d'évaluation de la sténose coronaire, un support d'informations et un dispositif électronique. Le procédé comprend les étapes suivantes : obtenir une image angiographique d'une artère coronaire ; réaliser une reconstruction tridimensionnelle d’un vaisseau selon l'image angiographique pour obtenir un modèle tridimensionnel du vaisseau de l'artère coronaire ; pour une branche cible de l'artère coronaire, effectuer un test de chute de pression sur le modèle de vaisseau tridimensionnel pour obtenir une relation de la fonction quadratique entre un flux sanguin et une pression du flux sanguin de la branche cible, la branche cible étant une branche quelconque de l'artère coronaire ; et évaluer la sténose de l'artère coronaire selon un coefficient constant de la relation de la fonction quadratique. Des modes de réalisation de la présente invention sont utilisés pour évaluer le degré de sténose d'un vaisseau.
