The Hancock Aortic Tissue Valve is a prosthetic heart valve used in cardiac surgery to replace a damaged or diseased aortic valve. [1] It is a bioprosthetic valve, meaning it is constructed using biological tissues, specifically porcine (pig) valve tissue. [ 2 ]
Valve replacement surgery is the replacement of one or more of the heart valves with either an artificial heart valve or a bioprosthesis (homograft from human tissue or xenograft e.g. from pig). It is an alternative to valve repair .
The shape of these valves do not mimic normal heart valves. Tissue heart valves are usually made from animal tissues, either animal heart valve tissue or animal pericardial tissue, commonly from the pig. The tissue is pretreated by removing antigens to prevent rejection and to prevent calcification. These valves tend to model after normal ...
A Maryland hospital said Monday he's doing well three days after the highly experimental surgery. While it's too soon to know if the operation really will work, it marks a step in the decades-long ...

An artificial heart valve is a one-way valve implanted into a person's heart to replace a heart valve that is not functioning properly (valvular heart disease). Artificial heart valves can be separated into three broad classes: mechanical heart valves, bioprosthetic tissue valves and engineered tissue valves.

Decellularization of porcine heart valves is the removal of cells along with antigenic cellular elements [1] by either physical or chemical decellularization of the tissue. [2] This decellularized valve tissue provides a scaffold with the remaining extracellular matrix (ECM) that can then be used for tissue engineering and valve replacement in ...
