FIELD: medicine.
SUBSTANCE: invention relates to medicine, namely to cardiovascular surgery. Two ligatures are applied to the left atrial appendage (LAA). In this case, the imposition of the first ligature is carried out at the base of the LAA. Then the top of the LAA is dissected, blood is removed from the cavity of the LAA. Then a "twist" is formed from the LAA along the long axis of the eyelet with fixation by the second ligature at a distance of 5-7 mm from the first one. After that, electrodes are placed between the ligatures and radiofrequency ablation is performed.
EFFECT: method makes it possible to prevent recanalization and the risk of residual LAA cavities, exclude restoration of spontaneous contractions in the LAA, and prevent cardioembolic complications.
