Background: Prosthesis sizing in transcatheter aortic valve replacement (TAVR) uses certain prosthesis oversizing (OS) to achieve device success. However, an increase in OS may increase the need for permanent pacemaker implantations (PPI).

An examination of 39 patients with heart diseases was performed before and after operations by the method of geometrical analysis of the nonlinear chaos (fractal) variability of the cardiac rhythm on the basis of the apparatus-programmed complex "Poly-spectrum". Five-minute-long registrations of ECG were carried on.

The structural-geometric and functional parameters of the heart in patients after mitral prosthetics with new full-flow valves in the long-term period [PDF]
Aim. To compare the results of mitral valve replacement with the full-flow mechanical valve MedInzh-ST and the classical prosthesis MedInzh-2, to learn the structural and functional parameters of the heart depending from the prosthesis in the long-tern ...
