TAVR Valve durability or Lifespan of TAVI Valve

The durability of TAVR (Transcatheter Aortic Valve Replacement) valves is an important consideration when deciding on treatment options for patients with aortic stenosis. While TAVR has been shown to be a safe and effective alternative to open-heart surgery for many patients, the long-term durability of the TAVR valve is still being studied.


Several studies have reported on the durability of TAVR valves over time, with results suggesting that TAVR valves may have similar or better durability compared to surgical valves in selected patients. For example, a study published in the New England Journal of Medicine in 2021 reported that among patients at intermediate surgical risk, the rate of structural valve deterioration at 5 years was similar between TAVR and SAVR (Surgical Aortic Valve Replacement) patients. Another study published in the Journal of the American College of Cardiology in 2020 reported that among high-risk patients, TAVR valves had similar or better durability compared to surgical valves up to 5 years.


However, it is important to note that the long-term durability of TAVR valves is still being studied and longer-term data are needed to fully understand the durability of these valves. Additionally, the durability of TAVR valves may vary depending on factors such as the patient's age, comorbidities, and the type of valve used.


In summary, while the long-term durability of TAVR valves is still being studied, current evidence suggests that TAVR valves may have similar or better durability compared to surgical valves in selected patients, particularly among those at high risk for surgery. Patients should discuss the potential benefits and risks of TAVR with their doctors to determine if it is the best treatment option for their individual case.


In real world experience, Edwards sapien and Medtronic Corevalve are being in use for long time since the time of TAVI evolution (>20 years) and good number of people have had functioning valve beyond 10-12 years - more so with balloon expandable valve.
