Purinergic ecto-enzymes in human and ovine aortic valves: indicators of bacterial nanocellulose scaffold cellularization

Artificial Cells, Nanomedicine, and Biotechnology
Purinergic signalling pathways play a vital role in the biological functions of the aortic valve (AV) through nucleotide and adenosine-dependent receptor effects.

Transcatheter vs surgical aortic valve replacement for bicuspid aortic valve disease

Surgical Practice, EarlyView.
Abstract Background Transcatheter aortic valve replacement (TAVR) has emerged as an acceptable and often preferred alternative to surgical aortic valve replacement (SAVR) for patients with severe aortic stenosis. However, the mid‐ and long‐term efficacy of TAVR in patients with bicuspid aortic valves (BAVs) remains unclear.

Impact of Frailty in Patients With Continuous‐Flow Left Ventricular Assist Device Therapy in End‐Stage Heart Failure: A Systematic Review and Meta‐Analysis

Artificial Organs, EarlyView.
Frailty significantly impacts clinical outcomes in LVAD recipients. This systematic review and meta‐analysis reveal that frail patients experience higher long‐term mortality but comparable short‐term mortality, hospital stay, and complication rates to non‐frail patients.

A Novel Polymer Film to Develop Heart Valve Prostheses

Polymers
Polymer heart valves are a promising alternative to bioprostheses, the use of which is limited by the risks of calcific deterioration of devitalized preserved animal tissues. This is especially relevant in connection with the increasingly widespread use of transcatheter valves.

Structural evolution of mechanical heart valves (review)

Вестник трансплантологии и искусственных органов
Prosthetic heart valves are widely used biomedical devices. The need for these prostheses is increasing due to the increasing life expectancy of the general population and the consequent incidence of age-related degenerative valvular defects.
