METHOD FOR ASSESSING CLINICAL SIGNIFICANCE OF ATRIAL FIBRILLATION IN DETERMINING INDICATION FOR ATRIAL FIBRILLATION INTERVENTIONAL TREATMENT Russian patent published in 2023 - IPC A61B5/02 A61B5/29 A61B6/03 A61B8/06 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, in particular to cardiology and cardiovascular surgery, and may be used in determining indications for atrial fibrillation (AF) interventional treatment in patients without typical clinical signs of AF. Multispiral computed tomography (MSCT) and transthoracic echocardiography with assessment of systolic and diastolic heart function are performed. The systolic heart function, diastolic heart function and a type of pulmonary vein inflow into the left atrium are assessed in a sequential manner. Based on the preoperative examination, the clinical significance of atrial fibrillation is determined in accordance with the following sequence: if systolic function is impaired, atrial fibrillation is considered clinically significant; if systolic function is not impaired, diastolic function is assessed; if diastolic function is impaired, MSCT is performed and pulmonary vein inflow into the left atrium is assessed. If Type 1, Type 2 or Type 4 is identified, atrial fibrillation is assessed as clinically significant, if Type 3, Type 5 or Type 6 is identified, atrial fibrillation is assessed as clinically insignificant.

EFFECT: invention provides for assessing clinical significance of AF for a particular person, which allows to specify indications for atrial fibrillation interventional treatment in asymptomatic patients by performing stage-by-stage analysis of cardiovascular system morphofunctional features.
