📍 Introduction:
If you've been told you need aortic valve replacement surgery, you face an important choice. Do you choose a mechanical or a tissue valve? In this video, we'll explore the pros and cons of each option, focusing on the Medtronic Avalus pericardial valve and its potential benefits.
📍 Mechanical Valves:
Mechanical valves, including the OnX carbon valve, can last a lifetime but require lifelong use of blood thinners like Warfarin. This medication necessitates regular blood tests and increases bleeding risks if injured.
📍 Tissue Valves:
Tissue valves, made from pig or cow tissue, don't last forever but have significantly improved. Modern examples include the Inspiris Resilia valve by Edwards Lifesciences and the Medtronic Avalus pericardial valve.
📍 Medtronic Avalus Pericardial Valve:
Today, we're focusing on the Avalus pericardial valve. This stented valve, treated with Amino Oleic Acid (AOA) to prevent calcification, has shown no structural deterioration at 5 years in the PERIGON trial.
📍 Long-term Durability:
Early evidence suggests the Avalus valve could last 10-20 years, comparable to the Inspiris Resilia valve. Its excellent hemodynamic function means less obstruction to blood flow, potentially offering better performance.
📍 Age Considerations:
Under 50: Mechanical valves like the OnX carbon valve are recommended.
Over 70: Tissue valves are generally preferred.
Ages 50-70: Both options are viable, with lifestyle and durability being key factors.
📍 TAVI (Transcatheter Aortic Valve Implantation):
If a tissue valve fails, TAVI can replace it without surgery, offering a less invasive solution.
📍 Minimally Invasive Surgery:
Modern surgery techniques allow valve replacement through a small cut between the ribs, leading to faster recovery and preserving the breastbone.
📍 Conclusion:
Choosing the right valve depends on various factors, including age, lifestyle, and medical history. Both mechanical and tissue valves have their benefits and potential drawbacks.
