A method of treating a subject in cardiac arrest comprises the steps of blocking the descending aorta (11) of the subject and perfusing the aortic arch (20) of the subject with a protective solution in an amount effective to deliver oxygen to the heart of the subject. The perfusing step is performed so that the protective solution infuses the aorta in a pulsatile rhythm. An apparatus (40) for carrying out this method includes a storage unit (41) for storing a protective solution, delivery apparatus (52) for delivering the protective solution to the aorta of the subject, wherein the delivery apparatus (52) is fluidly connected with the storage unit (41), and a pulsing device (65) connected with the delivery apparatus (52). The pulsing device (65) induces the protective solution to be delivered to the aorta in a pulsatile rhythm.

Ce procédé de traitement d'un sujet subissant un arrêt cardiaque consiste à bloquer l'aorte descendante (11) du sujet et à introduire par perfusion, dans la crosse (20) de cette aorte, une solution protectrice en une quantité efficace pour amener de l'oxygène au coeur dudit sujet. La perfusion se déroule de façon que la solution protectrice s'écoule dans l'aorte selon un rythme pulsatif. L'appareil (40), qui permet ce traitement, comprend un réservoir (41) de solution protectrice, un dispositif de libération (52) qui libère la solution protectrice dans l'aorte du sujet et qui est en liaison fluidique avec le réservoir (41), et un dispositif pulsant (65), connecté à ce dispositif de libération (52), qui permet à la solution protectrice d'être libérée dans l'aorte selon un rythme pulsatif.
