摘要：
FIELD: medicine.SUBSTANCE: group of inventions relates to medicine, specifically to cardiology. According to the first version, an introducer is installed for transseptal puncture SR0 in the upper hollow vein, an echocardiographic sensor is installed in the heart for interatrial septum (IAS) imaging. Introducer is used for transseptal puncture with transseptal needle from superior vena cava in right atrium (RA) under fluoscopic control. Introducer is installed in area of oval fossa IAS. At that, the transseptal needle tip is installed in the central-rear position in the IAS, which is controlled by the intracardiac EchoCG. IAS is visualized by setting the sensor for the ICEchoCG control. Central position of the transseptal needle in the IAS is confirmed by the equal distance of the needle tip from the muscle crus of IAS and the fibrous ring of the tricuspid valve. Posterior position is confirmed as follows: rotation of intracardiac sensor by 40–90° clockwise allows visualizing aortic root, and counterclockwise by 30–80° is a posterior wall of the left atrium (LA). Turn angle of clockwise rotation for visualization of aortic root by 10–20 % was more than turning angle counterclockwise for visualization of rear wall LA. According to the second version of the method, an introducer for transseptal puncture SR0 is inserted into an upper vena cava. Echocardiographic sensor is inserted into the esophagus. Introducer is provided for transseptal puncture with a transseptal needle from the superior vena cava into the right atrium (RA) under fluoscopic control. Introducer is installed in area of oval fossa IAS. At that, the transseptal needle tip is installed in the central-rear position in the IAS, which is controlled under TEEchoCG. Thereafter, the position data are determined by internal reference points – a flap ring of the aortic valve. IAS is sequentially visualized in two oesophageal positions: a short aortic valve and a bivalve valve. This position is visualized in the
