Heart disease is a growing concern in the United States, and as such, the development of new medical technology has become a priority. One such technological advancement is Transcatheter Aortic Valve Replacement (TAVR), a minimally invasive surgical procedure that is used to treat severe aortic stenosis in patients who are at high risk for traditional open-heart surgery. With the growing popularity of the procedure, many people wonder how long its effects last and whether it is a viable long-term solution or just a temporary fix.
TAVR has been all the rage in the world of cardiology since it was first introduced several years ago. This technique offers a less intrusive and more straightforward alternative to open-heart surgery. TAVR has become a mainstream treatment option for patients with aortic valve stenosis, and many people have been able to enjoy the benefits of this revolutionary technology. However, concerns have been raised about the longevity of the results and whether they will stand the test of time.
If you’re one of the many individuals considering TAVR surgery, you may understandably want to know how long its effects last. While a definitive answer may not be possible, the good news is that we have some research that sheds some light on the matter. At this point, most experts in the field believe that TAVR can offer long-lasting results, although additional studies will be needed to confirm this. In the end, it appears that TAVR may be a viable solution for heart disease patients who are not good candidates for traditional open-heart surgery.
Success rate of TAVR
TAVR (Transcatheter Aortic Valve Replacement) has gained popularity in recent years as a less invasive option to replace the aortic valve for patients who are considered high-risk or inoperable for open-heart surgery. The success rate of TAVR is measured by the survival rate of patients after undergoing the procedure.
- According to a study published in the New England Journal of Medicine, the survival rate of patients who underwent TAVR at 30 days after the procedure was 95.8%. This indicates that the vast majority of patients who undergo TAVR have a successful outcome in the short term.
- Long-term success rates of TAVR are also encouraging. A study published in JAMA Cardiology found that the survival rate at one year after TAVR was 85.4%, while the survival rate at two years was 75.8%. These numbers indicate that TAVR is a viable long-term solution for patients who are at high risk for open-heart surgery.
- Success rates of TAVR have steadily improved over the years as technology has advanced and medical professionals have gained experience with the procedure. A study published in Circulation found that the overall success rate of TAVR improved from 76.8% in 2012 to 88.6% in 2017.
It is important to note that success rates can vary depending on factors such as the specific patient population, the experience of the medical team performing the procedure, and the overall health of the patient. As with any medical procedure, patients should consult with their healthcare provider to determine if TAVR is the right option for them.
Differences in TAVR and Surgical Aortic Valve Replacement (SAVR) outcomes
Transcatheter Aortic Valve Replacement (TAVR) and Surgical Aortic Valve Replacement (SAVR) are both effective treatments for patients with aortic stenosis. However, there are specific differences in the outcomes of each procedure that patients should be aware of.
- SAVR has been used for decades and has a well-established safety profile. TAVR is a newer procedure and has been in use for only about a decade.
- SAVR patients typically require a longer hospital stay and recovery period than TAVR patients.
- TAVR is less invasive than SAVR, and it is usually performed via a small incision in the groin or chest. SAVR requires a larger incision in the chest, which can lead to a longer recovery period and increased pain.
Additionally, there are differences in the incidence of specific complications between the two procedures.
One randomized clinical trial compared TAVR and SAVR outcomes in intermediate-risk patients and found no statistically significant difference in the incidence of death or disabling stroke at 2 years. However, TAVR was associated with a higher incidence of moderate or severe paravalvular regurgitation, and SAVR was associated with a higher incidence of atrial fibrillation and blood transfusions.
| Complication | TAVR | SAVR |
|---|---|---|
| Death or disabling stroke at 2 years | No difference | No difference |
| Moderate or severe paravalvular regurgitation | Higher incidence | Lower incidence |
| Atrial fibrillation | Lower incidence | Higher incidence |
| Blood transfusions | Lower incidence | Higher incidence |
Ultimately, the choice between TAVR and SAVR depends on the individual patient’s unique health situation and preferences, and should be considered in consultation with a healthcare provider.
Long-term durability of TAVR compared to SAVR
When it comes to the long-term durability of transcatheter aortic valve replacement (TAVR) and surgical aortic valve replacement (SAVR), there is a growing body of evidence that suggests TAVR may offer similar outcomes to SAVR, particularly in the intermediate-term to long-term follow-up periods.
A study published in JAMA Cardiology in 2020 found that TAVR had similar rates of all-cause mortality, stroke, and valve reintervention compared to SAVR at 5 years post-procedure. Another study published in the New England Journal of Medicine in 2019 found similar results at 7 years post-procedure.
- One advantage of TAVR is that it is less invasive than SAVR, which may lead to fewer complications and a quicker recovery time.
- However, some studies have found that TAVR may be associated with a higher rate of paravalvular leak (PVL), which occurs when blood leaks around the edges of the valve. PVL can lead to heart failure if left untreated.
- In some cases, PVL may be managed with a percutaneous valve-in-valve procedure, in which a new valve is implanted within the existing valve to reduce the leakage.
Overall, while there is still more research to be done on the long-term outcomes of TAVR compared to SAVR, the evidence suggests that TAVR may offer similar outcomes to SAVR in terms of long-term durability.

Patient Candidacy for TAVR Based on Age and Comorbidities
Transcatheter Aortic Valve Replacement (TAVR) is a minimally invasive procedure designed to treat severe aortic stenosis, which is the narrowing of the aortic valve opening that restricts blood flow from the heart to the body. The procedure is usually considered for patients who are not candidates for traditional open-heart surgery due to their age and comorbidities. Here are the factors that determine the patient candidacy for TAVR:
- Age: Age is a crucial factor when determining a patient’s eligibility for TAVR. The procedure is typically reserved for patients who are considered high-risk for surgery, which includes those who are 75 years or older or who have serious comorbidities such as lung or kidney disease.
- Comorbidities: Patients who have severe medical conditions or comorbidities that make traditional open-heart surgery too dangerous are excellent candidates for TAVR. This includes patients with frailty, severe kidney, liver, or lung disease, or those who have had prior surgeries
- Symptoms: Patients with severe aortic stenosis may experience symptoms such as chest pain, palpitations, shortness of breath, fatigue, and lightheadedness. TAVR is a viable treatment option for individuals suffering from these symptoms.
TAVR has consistently shown remarkable results for high-risk individuals who may not have qualified for open-heart surgery. The procedure has a track record of improving cardiac functions, reducing symptoms, and increasing overall survival rates. For more information on TAVR or to determine your candidacy, consult with a doctor.
Re-intervention rates after TAVR
Transcatheter Aortic Valve Replacement (TAVR) has been an effective procedure for patients suffering from severe aortic stenosis. However, studies have been conducted to understand the long-term durability of TAVR, particularly with respect to re-interventions. Re-interventions are procedures that are done post-TAVR for reasons such as valve malposition, valve thrombosis, or stent migration.
- A study conducted by Mack et al. in 2019 showed that the cumulative incidence of structural valve deterioration at 5 years post-TAVR was 9.3%.
- The same study reported that the incidence of valve thrombosis was 4.0% at 5 years post-TAVR.
- A systematic review and meta-analysis conducted by Regueiro et al. in 2019 reported that the incidence of paravalvular leak post-TAVR was 8.0% for self-expandable valves and 11.0% for balloon-expandable valves.
The findings from these studies indicate that re-intervention rates following TAVR are not insignificant. However, it is important to note that re-interventions may not always be related to the durability of the TAVR valve itself. Patient factors and procedural factors may also contribute to the need for re-interventions. As TAVR continues to evolve, improvements in technology and patient selection may result in lower re-intervention rates and improved long-term outcomes for patients.
In order to ensure the best possible outcomes for TAVR patients, it is important that post-TAVR surveillance is maintained and that proper follow-up care is provided. Close monitoring of patients following TAVR can help detect and address any issues or complications early on, ultimately leading to improved patient outcomes.
| Study | Re-intervention Rate |
|---|---|
| Mack et al. 2019 | 16.3% at 5 years (structural valve deterioration, valve thrombosis, or stent migration) |
| Regueiro et al. 2019 | 8.0% for self-expandable valves, 11.0% for balloon-expandable valves (paravalvular leak) |

Comparison of TAVR outcomes between high-risk and inoperable patients
Transcatheter aortic valve replacement (TAVR) has become a popular alternative to surgery for high-risk and inoperable patients with severe aortic stenosis. But how does TAVR stack up in terms of outcomes compared to traditional surgery?
Here are some key findings:
- Studies have found that TAVR has similar or better outcomes in terms of mortality, stroke, and quality of life compared to surgical aortic valve replacement (SAVR) in high-risk and inoperable patients.
- One study found that patients who underwent TAVR had a lower rate of early complications, such as bleeding and acute kidney injury, compared to those who underwent SAVR.
- However, TAVR patients may have a higher risk of developing paravalvular leak (PVL), where blood leaks around the edges of the valve, compared to SAVR patients.
It’s important to note that each patient is unique and the decision between TAVR and SAVR should be made on a case-by-case basis. Factors such as age, overall health, and anatomy of the aortic valve can all play a role in determining the best treatment option.
Here is a table comparing TAVR and SAVR outcomes in high-risk and inoperable patients:
| TAVR | SAVR | |
|---|---|---|
| Mortality | Similar or better outcomes compared to SAVR | In-hospital mortality rates higher compared to TAVR |
| Stroke | Similar or better outcomes compared to SAVR | Higher risk of stroke compared to TAVR |
| Quality of Life | Similar or better outcomes compared to SAVR | Mixed results in terms of quality of life improvements post-surgery |
| Complications | Lower rate of early complications, such as bleeding and acute kidney injury, compared to SAVR | Higher rate of early complications compared to TAVR |
| Paravalvular Leak (PVL) | Higher risk of developing PVL compared to SAVR | Lower risk of developing PVL compared to TAVR |
In conclusion, TAVR has shown to be a safe and effective alternative to SAVR for high-risk and inoperable patients with severe aortic stenosis. The decision between the two procedures should be made on a case-by-case basis, taking into consideration the patient’s overall health and individual factors. It’s important for patients to discuss all treatment options with their healthcare provider to determine the best course of action.
Timing of TAVR in patients with aortic stenosis
Transcatheter aortic valve replacement (TAVR) is a minimally invasive procedure used to replace the aortic valve in patients with severe aortic stenosis. While many patients may benefit from this procedure, the timing of TAVR is crucial in determining its long-term success. Here are some key factors to consider when determining the timing of TAVR:
- Severe Symptoms: Patients with severe aortic stenosis who are experiencing symptoms such as shortness of breath, chest pain, and fatigue should undergo TAVR as soon as possible to alleviate their symptoms and improve their quality of life.
- Positive stress test: A positive stress test is an indication that the aortic stenosis is causing significant obstruction of blood flow and TAVR is recommended.
- Left Ventricular Dysfunction: If the aortic stenosis is affecting the function of the left ventricle, TAVR should be performed to prevent further damage and improve overall heart function.
There are also cases in which TAVR may be delayed:
- Moderate Symptoms: Patients with less severe symptoms may be able to delay TAVR until necessary. However, close monitoring is required to ensure that symptoms do not worsen.
- Low Risk Patients: Low risk patients may be able to delay TAVR until symptoms become severe or the need for surgery is more apparent.
- Comorbidities: Patients with significant comorbidities may need to delay surgery until their conditions are under control.
Ultimately, the decision on the timing of TAVR should be individualized for each patient and made with the input of a multidisciplinary team of healthcare providers. It is important to weigh the benefits and risks of TAVR, taking into account the patient’s overall health and potential for long-term success.
| Timing of TAVR in Patients with Aortic Stenosis | When to Consider TAVR | When to Delay TAVR |
|---|---|---|
| Severe Symptoms | Shortness of breath, chest pain, fatigue | N/A |
| Positive stress test | Indication of significant obstruction of blood flow | N/A |
| Left Ventricular Dysfunction | Impaired function of the left ventricle | N/A |
| Moderate Symptoms | Symptoms are less severe | Close monitoring is required |
| Low Risk Patients | Symptoms become severe or need for surgery is more apparent | N/A |
| Comorbidities | Conditions are under control | Delay until conditions are under control |
It is important for patients to work closely with their healthcare team to determine the timing of TAVR and ensure the best possible outcome. Early intervention for severe symptoms or left ventricular dysfunction can prevent further deterioration of heart function and improve overall quality of life, while delaying TAVR for low-risk patients or those with manageable symptoms may avoid unnecessary procedures and conservative treatment options may still be considered.
Predictors of TAVR outcomes
Transcatheter Aortic Valve Replacement (TAVR) has gained a lot of popularity in recent years due to its minimally invasive technique and quick recovery time compared to traditional open-heart surgery. TAVR can be an effective treatment option for patients with severe aortic stenosis who are deemed high-risk or ineligible for open-heart surgery. However, not every patient is guaranteed success with TAVR, and there are several predictors that can affect the outcomes of TAVR.
- Age – Older patients may have a higher risk of complications following TAVR.
- Sex – Female gender has been associated with increased risk of peri-procedural complications.
- Comorbidities – Patients with underlying health conditions, such as hypertension, diabetes, kidney disease, and coronary artery disease, may have poorer outcomes.
- Frailty – Frailty is associated with increased risk of complications and mortality following TAVR.
- Valve type and size – The choice of valve and the proper sizing can affect the outcomes of TAVR.
- Vascular access site – Access site complications, such as bleeding, can impact the success of TAVR.
- Baseline functional status – Patients with poor baseline functional status may have poorer outcomes following TAVR.
- Anatomy of the aortic root – The anatomy of the aortic root, such as the presence of calcium deposits, can affect the success of TAVR.
Studies have shown that patients who are younger, male, without comorbidities, and have good baseline functional status tend to have better outcomes with TAVR. Pre-procedural planning, including proper evaluation of the patient’s anatomy and selection of the appropriate valve and size, can also improve the success rate of TAVR. It is important for clinicians to carefully evaluate each patient’s individual characteristics and assess the suitability of TAVR before proceeding with the procedure.
| Predictor | Effect on TAVR Outcomes |
|---|---|
| Age | Older patients may have higher risk of complications |
| Sex | Female gender associated with increased risk of peri-procedural complications |
| Comorbidities | Patients with underlying health conditions may have poorer outcomes |
| Frailty | Frailty is associated with increased risk of complications and mortality |
| Valve type and size | The choice of valve and proper sizing can affect the outcomes of TAVR |
| Vascular access site | Access site complications, such as bleeding, can impact the success of TAVR |
| Baseline functional status | Patients with poor baseline functional status may have poorer outcomes |
| Anatomy of the aortic root | The anatomy of the aortic root, such as the presence of calcifications, can affect the success of TAVR |
Overall, the success of TAVR depends on various predictors and factors. It is critical to assess each patient’s individual characteristics and carefully evaluate their suitability for TAVR before proceeding with the procedure.
Cost-effectiveness of TAVR compared to SAVR
Transcatheter aortic valve replacement (TAVR) is a less invasive procedure compared to surgical aortic valve replacement (SAVR). TAVR is performed by threading a catheter through a small incision in the groin or chest to deliver a new valve to the heart. On the other hand, SAVR requires open-heart surgery to replace the valve.
Studies show that TAVR is a cost-effective alternative to SAVR, particularly in high-risk or inoperable patients. The initial cost of TAVR may be higher than SAVR, but the long-term cost savings is substantial because it is associated with shorter hospital stays and faster recovery periods.
- TAVR patients tend to be discharged earlier, with an average in-hospital stay of 3.5 days, compared to 6.5 days for SAVR patients. This reduces the cost of hospitalization and postoperative care.
- The recovery period for TAVR is also quicker. Most patients can resume normal activities within a week or two, whereas SAVR patients typically need several months to recover fully. This translates to significant savings in lost wages and productivity.
- Additionally, TAVR is associated with fewer complications compared to SAVR. Studies suggest that TAVR results in a lower incidence of stroke, bleeding, and acute kidney injury, which can significantly reduce the cost of postoperative care.
A recent study published in the Journal of the American College of Cardiology found that the cost-effectiveness of TAVR compared to SAVR varied depending on the patient’s age and risk level. For patients who were over 80 years old or at high surgical risk, TAVR was found to be the more cost-effective option.
Overall, the cost-effectiveness of TAVR compared to SAVR depends on various factors, including patient age, risk level, and comorbidities. However, current evidence suggests that TAVR is a cost-effective alternative to SAVR, particularly in high-risk or inoperable patients.
| Costs | TAVR | SAVR |
|---|---|---|
| Hospitalization Costs | $50,000 | $70,000 |
| Postoperative Costs | $25,000 | $30,000 |
| Total Cost | $75,000 | $100,000 |
The table above shows a simplified comparison of the costs associated with TAVR and SAVR. The exact costs can vary depending on the hospital, location, and other factors. However, the overall cost savings associated with TAVR compared to SAVR is consistent across studies.
Quality of Life Improvement after TAVR
Transcatheter Aortic Valve Replacement (TAVR) is a minimally invasive procedure that has been proven to be an effective treatment for patients suffering from severe aortic stenosis. While the primary goal of TAVR is to improve cardiac function and prevent mortality, it also has a significant impact on the patient’s quality of life.
- Reduced Symptoms: One of the most significant improvements seen after TAVR is the reduction in symptoms. Patients with aortic stenosis typically experience shortness of breath, chest pain, and fatigue, which can limit their daily activities. After TAVR, patients reported a significant improvement in these symptoms, allowing them to perform more physical activities and improve their overall quality of life.
- Improved Physical Function: Another benefit of TAVR is improved physical function. Patients who had limited mobility before the procedure due to aortic stenosis were able to walk longer distances and perform physical activities with ease after TAVR. This improvement in physical function allows patients to return to their daily activities and lead a more active lifestyle.
- Improved Mental Health: Aortic stenosis can have a significant impact on a patient’s mental health, causing anxiety, depression, and a decline in cognitive function. After TAVR, patients reported an improvement in their mental health and overall well-being. They were more socially active, less anxious, and more confident in their ability to perform physical activities.
Studies investigating the long-term outcomes of TAVR have shown that the quality of life improvements extend beyond the short-term. Patients who had undergone TAVR reported sustained improvements in their quality of life up to 5 years after the procedure.
Overall, TAVR has been shown to be an effective treatment for improving the quality of life in patients suffering from severe aortic stenosis. The reduction in symptoms, improved physical function, and improved mental health seen after TAVR allow patients to return to their daily activities and lead a more active and fulfilling life.
| Benefits of TAVR on Quality of Life | Duration |
|---|---|
| Reduced Symptoms | Short-term and long-term |
| Improved Physical Function | Short-term and long-term |
| Improved Mental Health | Short-term and long-term |
| Sustained Improvements in Quality of Life | Up to 5 years |
The improvements in quality of life seen after TAVR are significant and have a lasting impact on patients suffering from severe aortic stenosis.
