Summary

This trial is testing a new heart valve to see if it is safe and effective in treating aortic stenosis in high and extreme risk patients.

Who is the study for?
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.Check my eligibility
What is being tested?
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.See study design
What are the potential side effects?
Potential side effects may include bleeding complications due to anti-clotting medications used during the procedure; vascular complications from inserting devices into blood vessels; irregular heartbeats; stroke; infection risks associated with any invasive procedure; damage to surrounding structures like arteries or ventricles.

Mechanism Of Action

Prior Approvals
Other Research
Aortic valve stenosis is commonly treated through surgical aortic valve replacement (SAVR) or transcatheter aortic valve replacement (TAVR). SAVR involves open-heart surgery to replace the diseased valve with a mechanical or biological prosthetic valve, which improves blood flow and reduces symptoms by eliminating the obstruction. TAVR, a less invasive alternative, involves threading a catheter through the blood vessels to implant a new valve within the diseased aortic valve. This method is particularly beneficial for high-risk patients who may not be suitable candidates for open-heart surgery. Both treatments aim to restore normal valve function, thereby improving cardiac output and alleviating symptoms such as shortness of breath, chest pain, and fatigue, which are critical for enhancing the quality of life and survival in patients with severe aortic stenosis.
