What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests a new heart valve system called the Portico Valve for individuals with severe aortic stenosis, a condition where the heart's aortic valve doesn't open properly. Researchers aim to determine if this new valve is safe and effective compared to other available valves. The trial includes different groups, one specifically for those whose previous valve surgery didn't succeed as planned. This trial might suit individuals experiencing symptoms like fatigue or chest pain due to aortic stenosis, especially if surgery poses significant risks. As an unphased trial, it offers a unique opportunity to contribute to medical research and potentially benefit from an innovative treatment option.

Do I need to stop my current medications for the trial?

The trial protocol does not specify if you need to stop taking your current medications. However, if you have a known hypersensitivity or contraindication to aspirin, heparin, ticlopidine (Ticlid), or clopidogrel (Plavix), you may be excluded from the trial.

Will I have to stop taking my current medications?

The trial information does not specify if you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

What prior data suggests that the Portico Transcatheter Aortic Valve System is safe for treating aortic stenosis?

Research has shown that the Portico Transcatheter Aortic Valve System is safe. One study found the Portico valve to be as safe and effective as other options, with patients experiencing low rates of complications and death. Another review noted a strong safety record for the system, with very few serious side effects reported in the first 30 days. Additionally, the FlexNav delivery system used with the Portico valve proved safe and provided lasting benefits for over a year. Overall, evidence suggests that patients tolerate the Portico valve well.¹ ² ³ ⁴ ⁵

Why are researchers excited about this trial?

The Portico Valve System is unique because it offers a re-sheathable design that allows for precise placement during the procedure, which is a significant improvement over many existing transcatheter aortic valves. This feature can potentially reduce complications and improve outcomes for patients with aortic stenosis. Additionally, the FlexNav delivery system used with the Portico Valve offers enhanced flexibility and control, making the procedure less invasive and potentially safer for patients. Researchers are excited about these innovations because they could lead to better patient experiences and outcomes compared to the current standard treatments.

What evidence suggests that the Portico Valve is effective for treating aortic stenosis?

Research has shown that the Portico Valve System effectively treats severe aortic stenosis, a condition where the heart's aortic valve narrows excessively. In this trial, participants may receive the Portico Valve System, which studies indicate is as safe and effective as other valves. For instance, one study found that patients experienced positive results a year after receiving the Portico valve, with few complications. Another study confirmed that the Portico Valve System meets safety and effectiveness standards compared to other treatments. Overall, the Portico Valve System appears promising for those needing a new aortic valve.¹ ⁶ ⁷ ⁸ ⁹

Are You a Good Fit for This Trial?

This trial is for adults over 21 with severe symptomatic aortic valve stenosis who are at high or extreme risk for surgery, as determined by specific health criteria and consultations. Participants must be able to attend follow-up visits, have certain heart function classifications (NYHA II-IV), and an aortic annulus size of 19-27mm. Exclusions include recent heart attacks, certain valve abnormalities, blood disorders, uncontrolled coronary artery disease, kidney failure on dialysis, active infections within the past six months, life expectancy less than one year due to other diseases.

Inclusion Criteria

Doctors agree surgery is too risky for me due to high chances of death or serious harm.

I have severe aortic valve stenosis confirmed by an echo test within the last 60 days.

I have symptoms of aortic stenosis and my activity is somewhat to severely limited.

What Are the Treatments Tested in This Trial?

Interventions

Portico Re-sheathable Transcatheter Aortic Valve System

Trial Overview The PORTICO trial tests the safety and effectiveness of the St Jude Medical Portico Transcatheter Heart Valve in patients with severe aortic stenosis who are not good candidates for traditional surgery. The study compares this new device against commercially available transcatheter valves using transfemoral (through the leg) and alternative delivery methods.

Published Research Related to This Trial

The self-expanding Portico valve demonstrated comparable hemodynamic performance to the balloon-expandable SAPIEN XT valve in a study of 22 patients, with no significant differences in transaortic gradients or effective orifice areas after one month.

Both valves showed similar rates of severe prosthesis-patient mismatch and paravalvular leaks, indicating that the Portico valve is a safe alternative for patients with severe aortic stenosis and small annuli.

Self-expanding Portico Valve Versus Balloon-expandable SAPIEN XT Valve in Patients With Small Aortic Annuli: Comparison of Hemodynamic Performance.Del Trigo, M., Dahou, A., Webb, JG., et al.[2017]

The Portico system is a self-expanding valve prosthesis designed for transcatheter aortic valve replacement (TAVR), which is a minimally invasive procedure for patients with aortic valve stenosis.

The abstract outlines a 10-step implantation procedure for the Portico system, providing practical tips based on the authors' personal experiences to enhance the success of the procedure.

Transcatheter Aortic Valve Replacement Using the Portico System: 10 Things to Remember.Tzikas, A., Amrane, H., Bedogni, F., et al.[2018]

The Portico TAVI system demonstrated significant and lasting improvements in aortic valve function in high-risk patients with severe aortic stenosis, with a low all-cause mortality rate of 3.6% at 30 days and 13.8% at 1 year among 222 patients studied.

At 1 year, 74.8% of patients showed improvement in their functional status, indicating that the Portico TAVI system is both safe and effective for treating severe aortic stenosis in elderly patients.
