FIELD: medicine, cardiosurgery.
SUBSTANCE: one should perform endocardiac radio-frequency impact upon atrial myocardium by "Labyrinth-III" modified scheme. Moreover, it is necessary to carry out epi- and endocardiac stages of radio-frequency atrial fragmentation. For this purpose, one should apply a purse-string suture onto the mouth of right superior pulmonary vein to apply an electrode through it for performing left-atrial endocardiac stage of radio-frequency atrial fragmentation by "Labyrinth-III" scheme under visual control of left atrial cavity. The innovation enables to carry out epi- and endocardiac stages of "Labyrinth-III" procedure simultaneously without lancing left cardiac departments.
EFFECT: higher efficiency of therapy.
