Patent

CA 2389863

Various methods and devices for treating a patient who has lost, or is at risk of losing cardiac function by cardiac ischemia are disclosed. Treatment includes first imaging a patient's heart, or a portion thereof, to identify underperfused regions of cardiac muscle, and a source of oxygenated blood that is proximate to the underperfused region. Between the underperfused regions and the oxygenated blood source, a target area is selected where thermal or mechanical injury is introduced, and optionally reintroduced, to convert initial capillary blush, resulting from the injury.

L'invention concerne différents procédés et dispositifs permettant de traiter un patient ayant perdu ou risquant de perdre sa fonction cardiaque en raison d'une ischémie cardiaque. Le traitement consiste à mettre en image la totalité ou une partie du coeur d'un patient afin d'identifier des régions du muscle cardiaque en sous-perfusion et une source de sang oxygéné qui se trouve à proximité de la région en sous-perfusion. Entre les régions en sous-perfusion et la source de sang oxygéné, on choisit une zone cible où on introduit, et éventuellement on réintroduit, une lésion thermique ou mécanique, afin de transformer le rougissement capillaire initial produit par la lésion.
