METHODOLOGY OF PACING IN TRANSCATHETER AORTIC VALVE REPLACEMENT USING AN ULTRA-RIGID GUIDEWIRE IN THE LEFT VENTRICLE AND A CORONARY GUIDEWIRE IN THE FEMORAL ARTERY

Highlights

• Various methods of over-frequency ventricular stimulation in endovascular interventions on heart valves are analyzed.
• A new method of pacing using an over-stiff guidewire in the left ventricle and a coronary guidewire in the femoral artery is presented in transcatheter aortic valve replacement.

The publication presents and substantiates the methodology of pacing in TIAC using an ultra-rigid conductor in the left ventricle and a coronary conductor in the femoral artery. A technique for ultra–frequent stimulation of the ventricles of the heart is described, in particular, the use of a coronary artery in the femoral artery, the approach is illustrated by a clinical example. The proposed method makes it possible to successfully perform transcatheter intervention on the aortic valve: it provides stable, ultra-frequent stimulation of the ventricles at small amplitudes, while it does not require additional manipulations, new accesses, special tools and additional material costs.
