Title (EN) CARDIAC ABLATION USING MICROBUBBLES
(FR) ABLATION CARDIAQUE FAISANT APPEL A DES MICROBULLES
Abstract: front page image
(EN)In a cardiac ablation procedure, ultrasonic energy is emitted from an ultrasonic ablation device (28) and is focused on myocardial tissue (30) within the wall of the heart or within the wall of a blood vessel connected to the heart (10). Ultrasound attenuation of the cardiac tissue is selectively increased by introducing microbubbles into the circulatory system of the subject so that the microbubbles enter the coronary arteries and pass into the myocardial tissue.
(FR)Dans une opération d'ablation cardiaque, de l'énergie ultrasonore est émise par un dispositif d'ablation ultrasonore (28), et est dirigée sur le tissu myocardique (30) à l'intérieur de la paroi du coeur ou de la paroi d'un vaisseau sanguin relié au coeur (10). L'atténuation d'ultrasons du tissu cardiaque est augmentée de façon sélective par l'introduction de microbulles dans le système circulatoire du sujet, afin que les microbulles pénètrent dans les artères coronariennes et passent dans le tissu myocardique.
