What is a bovine pericardial patch made of?
Principally composed of collagen, pericardium provides strength and elasticity. Bovine pericardium is used extensively in applications including bio-prosthetic heart valves, dural closure, bone and dental membranes, and surgical buttressing.
What is a bovine pericardial valve?
The pericardial heart valve was invented by Marian Ionescu, a British surgeon working at the General Infirmary in Leeds, England. He created this artificial bioprosthetic heart valve as a three-cusp structure made of chemically treated bovine pericardium attached to a Dacron cloth-covered titanium frame.
Is a bovine pericardial patch synthetic?
Bovine pericardial patch, which is an acellular xenograft material, may reduce the risk of perioperative fatal stroke, death, and infection compared to other synthetic patches.
What is porcine pericardium?
Porcine pericardium was obtained from genetically engineered pigs with a mutation in the GGTA-1 gene (GTKO) and fixed in 0.6% glutaraldehyde, and used to develop a new surgical valve design. Juvenile sheep implants demonstrated normal valve function with no acute thrombogenic response for either material.
What is a bovine patch used for?
Bovine pericardium (BP) is widely used in surgery and is commonly used as a patch after arteriotomy in cardiovascular surgery. BP patches have several advantages compared with prosthetic patches, including superior biocompatability, easy handling, less suture line bleeding, and possibly reduced rates of infection.
What is bovine pericardial patch angioplasty?
Bovine pericardium is commonly used in vascular surgery, typically as a material used for patch closure of a longitudinal arteriotomy (“patch angioplasty”).
Where do bovine valves come from?
A cadaveric valve comes from a human donor. Bovine valves are recovered from cows and porcine valves come from pigs. The valve may be an actual valve recovered from a donor or is manufactured from donor tissue such as the pericardium, the sac that surrounds the heart.
How long does a pericardial patch last?
The median time from fistula formation to bovine pericardial patch was 15 months (interquartile range (IQR): 5-43). Median duration of follow-up was 14 months (IQR: 5-18). Primary patency at 6, 12, 18 and 24 months was 91%, 66%, 61% and 54%, respectively.
Is a bovine patch Zooplastic?
Although bovine patch appears to be graft tissue derived from animal, there is no device character for zooplastic at table 04U.
How long do bovine valves last?
While new technologies are being designed and tested, cow valve replacements typically last between 10-20 years. The main advantage of mechanical valves is that they are very durable and expected to last the life of the patient.
Which heart valve is most commonly repaired?
Two valves—the aortic and mitral valves—are the most common ones that need repair or replacement surgery. Defects are less common in the two other valves, but they can also develop problems that require surgery.
What does a pericardial patch do?
The Pericardial Patch with EnCap AC Technology* combines strong, durable bovine pericardium with a proprietary anti-calcification treatment, making it suitable for a variety of cardiac repairs while offering improved handling and enhanced biocompatibility.
