Which Biological Properties of Heart Valves Are Relevant to Tissue Engineering?

Frontiers in Cardiovascular Medicine, 2020
Over the last 20 years, the designs of tissue engineered heart valves have evolved considerably. An initial focus on replicating the mechanical and structural features of semilunar valves has expanded to endeavors to mimic the biological behavior of ...

Polymeric prosthetic heart valves: A review of current technologies and future directions

Frontiers in Cardiovascular Medicine, 2023
Valvular heart disease is an important source of cardiovascular morbidity and mortality. Current prosthetic valve replacement options, such as bioprosthetic and mechanical heart valves are limited by structural valve degeneration requiring reoperation or

Immune Privilege of Heart Valves

Frontiers in Immunology, 2021
Immune privilege is an evolutionary adaptation that protects vital tissues with limited regenerative capacity from collateral damage by the immune response. Classical examples include the anterior chamber of the eye and the brain.

Fluid dynamic characterization of a polymeric heart valve prototype (Poli-Valve) tested under continuous and pulsatile flow conditions. [PDF]

, 2015
PURPOSE: Only mechanical and biological heart valve prostheses are currently commercially available. The former show longer durability but require anticoagulant therapy; the latter display better fluid dynamic behavior but do not have adequate durability.

Ultrasound Guidance to Reduce Vascular and Bleeding Complications of Percutaneous Transfemoral Transcatheter Aortic Valve Replacement: A Propensity Score–Matched Comparison

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2020
Background Ultrasound (US) guidance provides the unique opportunity to control the puncture zone of the artery during transfemoral transcatheter aortic valve replacement and may decrease major vascular complications (VC) and life‐threatening or major ...
