METHOD FOR SELECTING A METHOD FOR CATHETER ISOLATION OF PULMONARY VEINS IN PATIENTS WITH ATRIAL FIBRILLATION Russian patent published in 2020 - IPC A61B5/00 A61B8/00 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely to cardiovascular surgery. Operation is preceded by multispiral cardiac computed tomography (MSCT) with subsequent determination of the type of pulmonary vein (PV) inflow into the left atrium (LA). That is followed by determining the method of catheter isolation of pulmonary veins taking into account the revealed type of PV inflow into the LA. If observing the MSCT heart data to detect the presence of a "typical anatomy", then for the surgical management of the AF, a cryo-abdominal PV isolation is selected. If the presence of the "loose type" or "mixed type" is determined by MSCT heart data, the radiofrequency catheter isolation PV is chosen for the surgical management of the AF. If the MSCT data are used to determine the presence of a "left PV collector", or "contralateral PV", or "right PV collector", then the PV collector shaft head diameter is measured. If its maximum diameter is less than the maximum diameter of the cryo-balloon, then for the surgical treatment of AF the cryo-balloon isolation of PV is chosen. If the maximum diameter of the mouth of the PV collector is equal to or exceeds the maximum diameter of the cryo-balloon, then the surgical management of AF is followed by selecting the radiofrequency catheter isolation of the pulmonary veins.

EFFECT: method enables reducing the risk of developing intraoperative complications, reducing the length of the surgical intervention, reducing the radiation exposure and improving the intraoperative effectiveness of the surgical management of atrial fibrillation (AF).
