FIELD: medicine.;SUBSTANCE: invention relates to medicine, particularly to cardiovascular surgery. Produce dissection blunt by duplicating the pericardium posterior to the inferior vena cava immediately at the point of its entry into the right atrium. Then the dissection is performed by the blunt path of the pericardial duplication posterior to the superior vena cava immediately at the point of its entry into the right atrium. Through the formed behind the inferior vena cava, fenestration into the oblique sine of the pericardium is introduced by the tube guide. Through the posterior inferior vena cava, fenestrated into the transverse sinus of the pericardium, a tube guide is inserted. Then artificial circulation begins: they squeeze the aorta; produce infusion of cardioplegic solution. Cardioplegia is achieved. Heart is completely turned out of the pericardial cavity. In this case, the traction of the heart is carried out in such a way that the apex of the heart is directed to the patient's jugular cutting. In the direction of the left pulmonary veins, the bipolar radio frequency ablator-clamp is installed. Then, by traction of the guides, the bunches of the bipolar radiofrequency ablator-clamp are inserted into the pericardial cavity and envelop the left pulmonary veins and 2/3 of the posterior wall of the left atrium. Guides are disconnected from the bipolar radio frequency ablator-clamp. Radio frequency exposure is applied. Bipolar radiofrequency ablator-clamp is removed from the pericardial cavity. In direction of the right pulmonary veins, the bipolar radio frequency ablator-clamp is installed. By traction of the guides, the bipolar radio frequency ablator clamps are inserted into the pericardial cavity and envelop the right pulmonary veins and 2/3 of the posterior wall of the left atrium. Radio frequency exposure is applied. Bipolar radiofrequency ablator-clamp is removed from the pericardial cavity.;EFFECT: method allows not to open the cavity of the left atrium, and as a result, to eliminate the risk of bleeding from the sutures of the left atrium, to shorten the duration of the operation, and also to reduce the total number of radio-frequency effects on the wall of the left atrium.;1 cl
