The aim of the study was to evaluate whether sympathetic denervation trunk and orifices pulmonary arteries could reduce hypertension help in managing atrial fibrillation.In addition, we aimed identify main predictors recurrent rhythm disturbances patients with mitral valve dysfunction complicated by fibrillation high pressure.Materials Methods.We analyzed results surgical treatment 140 defects high-grade (more than 40 mm Hg).In group (n=51), intervention included correction defect, for according Maze IV, radiofrequency artery order correct hypertension.In control (n=89), similar heart underwent repair (Maze IV), but no or performed.Results.We found that circular effectively reduced pressure.The proposed procedure reverse remodeling cavities, especially left atrium (p=0.01), a decrease hypertension, permanent restoration sinus after IV (p=0.008).The these combined are arrhythmias lasting over 5 years (p=0.04),initial more 60 Hg (p=0.028),concomitant severe tricuspid insufficiency (p=0.006) atherosclerotic lesions brachiocephalic cerebral vessels.
