METHOD OF INTRAOPERATIVE IMAGING AND CONTROL OF THE POSITION OF THE ELECTRODE DURING IMPLANTATION OF THE ELECTRODE INTO THE CARDIAC CONDUCTION SYSTEM Russian patent published in 2023 - IPC A61B6/00 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely to interventional surgical arrhythmology, and can be used for intraoperative imaging and control of the position of the electrode during implantation of the electrode into the cardiac conduction system. At the preoperative stage, multispiral computed tomography (MSCT) of the heart is performed with contrasting cardiac chambers with the achievement of an average contrast density of the left chambers exceeding the contrast density of the right chambers by at least 80HU, and the difference in the density of the myocardium and the cavity of the right ventricle by at least 20HU. The MSCT data is loaded into the angiographic complex and a segmented three-dimensional model of the heart is created. A three-dimensional image of the heart obtained according to MSCT data at the preoperative stage is combined with a three-dimensional image of the heart obtained intraoperatively from an angiographic complex during rotational angiography, according to bone structures - vertebral column, ribs, and soft structures – heart shadow, aortic arch. A mask of a three-dimensional model of the heart is formed against the background of images obtained from the angiographic complex. Intraoperative control of the position of the implanted electrode is carried out by re-combining the volumetric image of the heart with the implanted electrode from the angiographic complex when performing repeated rotational angiography with a volumetric image of the heart obtained according to MSCT data at the preoperative stage.

EFFECT: method provides control of the position of the electrode relative to the interventricular septum due to the claimed imaging technique.
