Synopsis

Source of validity: Scientific
Rating (out of 5): 3

Animal tissues, particularly those derived from heart valves and blood vessels of pigs (porcine) or cows (bovine), are scientifically validated and widely used in modern cardiovascular medicine, especially in the form of bioprosthetic heart valves and vascular grafts. These bioprosthetic valves are used to replace diseased heart valves in patients with valvular heart disease, providing a life-saving alternative to mechanical valves or long-term medical therapy. The use of animal tissue in these devices is supported by decades of clinical research demonstrating their efficacy, biocompatibility, and lower risk of blood clot formation compared to mechanical alternatives. While these tissues are treated and processed to reduce the risk of immunogenic reactions and infections, their function remains crucial in restoring normal cardiovascular physiology.

Beyond heart valves, animal-derived collagen and pericardial tissues are employed in vascular patches and conduits for reconstructive cardiovascular surgery. Their use is not based on traditional or folkloric medical practices but is a result of modern biomedical engineering and rigorous scientific investigation. Numerous clinical trials and long-term follow-up studies attesting to the safety and effectiveness of animal tissue-derived cardiovascular implants provide a moderate-to-strong evidence base (rated 3 out of 5, as some limitations exist such as durability and the potential for calcification over time). Overall, animal tissue plays a scientifically substantiated role in the treatment and support of cardiovascular disease.
