Mechanical & biological aortic valves

Mechanical & biological aortic valves

The debate over whether to use mechanical or biological aortic valves will continue for years. Although the scientific evidence on the effectiveness of mechanical aortic valves is limited, they are often the preferred option for patients with aortic dissection. The advantages of biological aortic valves include their ability to function better in the body and shorter recovery periods. Moreover, the surgical technique is considered safe and often requires less postoperative discomfort than its counterpart.

The hazard ratios and survival rates for both mechanical and biological valves are marginal, which means that the mortality benefit associated with mechanical aortic valves persists even when the patients are older. Therefore, patients with mechanical valves need to take a blood thinner such as warfarin every day. In addition, blood cells can be torn by the metal pieces in mechanical valves, leading to the formation of blood clots.

Despite these shortcomings, mechanical aortic valves have a high success rate, with about 200 000 operations performed each year. This success rate makes it the preferred choice for younger patients. However, their drawbacks make them unsuitable for older patients. For one, despite their high success rate, mechanical aortic valves require lifelong anticoagulation. Bioprosthetic valves are more likely to last for many years, freeing patients from the need for oral anticoagulation.

The mechanical aortic valves are fabricated from special materials and are more durable. The advantage of using mechanical valves is that they are more convenient for patients with ageing and senility. Moreover, mechanical aortic valves are considered safer for younger patients. Unlike bioprostheses, the complications of these valves are minimal and rarely serious. The risk of blood clots is low for biological aortic valvuloplasty.

While mechanical aortic valves are generally safer than bioprosthetic aortic valves, they are not without their own disadvantages. For example, a bioprosthetic valve may be associated with lower late survival in older patients, but it is not an independent predictor of age. In addition, mechanical aortic valves are also more likely to result in clots that can lead to stroke or heart attack.

Compared to bioprosthetic aortic valves, the mechanical prosthesis is more likely to be long-lasting. The patients undergoing a mechanical prosthesis are usually younger than those receiving a bioprosthesis. Additionally, patients with mechanical aortic valves have a lower risk of cardiovascular disease. In the case of the mechanical aortic valve, they can also have less severe side effects than their counterparts.

While the mechanical aortic valves are the most durable, they do come with a risk of blood clots and require long-term blood-thinning. In addition, mechanical aortic valves may be the only option for patients with severe aortic dissection. A patient with a bioprosthetic aortic valve is likely to experience lower late mortality, but it will be more expensive than a bioprosthetic.

The mechanical aortic valves have less risk of failure than the biological ones, but they do require life-long anticoagulation. In addition, mechanical aortic valves are more expensive than their counterparts and need to be replaced every 20 to 30 years. They may also be more difficult to maintain. But, in general, they are the better option for patients with aortic dissections and severe aortic dissections.

In comparison to biological aortic valves, mechanical aortic valves can last for several decades. These are more durable, but they require lifelong anticoagulation. They also require less invasive surgery and are therefore often the preferred option for young patients. These artificial aortic valves are not permanent. They are only meant to last for a few years. They should be replaced as early as possible, though.

Tissue valves, or biological aortic valves, are made of animal tissue. They are derived from either human or animal tissues. These tissue valves are fixed with a preserving solution. Afterward, they may be attached to a flexible frame. The fabric surrounding the bioprosthetic valve is often covered in a knitted material. These types of aortic valves are made of human or animal tissue, and are often called homografts.
