Artificial Organs, Volume 47, Issue 1, Page 168-179, January 2023., 2023 Peak oxygen consumption, VO2peak, was associated with short‐term 3‐months‐rehospitalization in heart failure patients with reduced ejection fraction (HFrEF). Exercise oscillatory ventilation (EOV), representing fluctuations of pulmonary artery pressure, can be observed in heart failure patients with reduced ejection fraction with and without left ...

Artificial Organs, Volume 47, Issue 1, Page 129-137, January 2023., 2023 Device‐based therapies for heart failure with preserved ejection fraction are limited, but the left atrial assist device pump is making progress as one option. Since the implantation site is unique, options for device orientation, driveline exteriorization, and exit sites must be demonstrated.

Heart, Vessels and Transplantation, 2022 Advances in the diagnosis and management of congenital heart disease (CHD) have resulted in an increased number of patients living into adulthood. Despite increased survival, these patients often require surgery at a young age and are susceptible to developing complications related to the degeneration of surgical prostheses and valves.

Transcatheter Valve Unable to Cure Patient–Prosthesis Mismatch of Mosaic Bioprosthesis
The Thoracic & Cardiovascular Surgeon Reports, 2016 Transcatheter aortic valve implantation (TAVI) has been recently established as a less invasive alternative to conventional aortic valve replacement (CAVR) in patients presenting with expected high procedural risk.

“Valve-On-Valve” — an alternative method of surgical treatment of tissue valve dysfunctions
Российский кардиологический журнал, 2019 Every year, the frequency of use of biological prostheses for treatment of valvular heart disease increases.The implantation of a biological prosthesis allows avoiding lifelong anticoagulant therapy, but at the same time it may require further ...
