MULTICENTER EVALUATION OF PROSTHESIS OVERSIZING FOR THE SAPIEN 3 TRANSCATHETER HEART VALVE – IMPACT ON NEW PACEMAKER IMPLANTATIONS

open access: closedJournal of the American College of Cardiology, 2017
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).

[Prognostication of the outcome of heart valve prosthesis implantation by the method of nonlinear chaos dynamics of the heart rate].

open access: closedVestnik khirurgii imeni I. I. Grekova, 2001
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.

[Use of cytochrome C in the prevention of myocardial reperfusion injury during heart valve prosthesis implantation under conditions of extracorporeal circulation].

open access: closedVestnik khirurgii imeni I. I. Grekova, 2001
Cytochrome C used at the postischemic period causes a rapid reestablishment of coronary circulation, hemodynamic parameters, prevents activation of lipid peroxidation in reoxygenation of the heart after prolonged total myocardial ischemia in patients with acute bacterial endocarditis in whom the prostheses of heart valves had been fulfilled.

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]

open access: yesКардиоСоматика, 2022
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 ...

The First Experience of Aortic Valve Repeated Replacement Using the “Valve in Valve” Technique in a Patient With Dysfunction of a Biological Prosthesis

open access: yesНеотложная медицинская помощь, 2021
Introduction. Aortic valve replacement in cardiopulmonary bypass with suture fixation of the prosthesis is the “gold standard” in cardiac surgery. Currently, the frequency of use of heart valve bioprostheses is increasing in older patients.
