What is the mechanism of action of this treatment?

Aortic Valve Replacement Surgery is the most common treatment for severe Aortic Regurgitation. This surgical intervention replaces the malfunctioning aortic valve with a prosthetic valve, ensuring proper closure and preventing blood from leaking back into the heart chamber. By maintaining efficient blood flow and reducing the heart's workload, this treatment improves heart function and alleviates symptoms such as fatigue and shortness of breath. This mechanism is crucial for AR patients as it directly addresses the root cause of their condition, significantly enhancing their quality of life.

What side effects are associated with this type of intervention?

Aortic Valve Replacement Surgery, the preferred treatment for severe Aortic Regurgitation, carries several potential side effects and risks. Common surgical risks include infection, bleeding, and adverse reactions to anesthesia. Specific complications related to valve replacement can include valve dysfunction or failure, blood clots leading to stroke or heart attack, and issues related to the prosthetic valve such as wear and tear or the need for future replacement. Additionally, patients may experience arrhythmias and, in rare cases, complications such as aortic dissection or endocarditis.

What prior FDA approvals exist?

Aortic regurgitation is primarily treated through surgical intervention, specifically aortic valve replacement surgery. This procedure involves replacing the malfunctioning aortic valve to prevent blood leakage and improve heart function. The FDA has approved various types of aortic valve replacement devices, including mechanical valves, bioprosthetic valves, and transcatheter aortic valve replacement (TAVR) systems. These devices are designed to restore proper valve function and are indicated for patients with severe aortic regurgitation who are symptomatic or at risk of heart failure.

What other types of research exist?

One promising novel alternative to aortic valve replacement surgery for aortic regurgitation patients is Transcatheter Aortic Valve Replacement (TAVR). The JenaValve Pericardial TAVR system, as studied in the ALIGN-AR EFS trial, is designed specifically for treating severe aortic regurgitation. This minimally invasive procedure involves placing a new valve within the existing malfunctioning valve via a catheter, reducing the need for open-heart surgery and potentially offering quicker recovery times and fewer complications.

Summary

This trial examines using TAVR with the JenaValve to treat patients with severe Aortic Regurgitation. TAVR is a less invasive procedure that replaces the faulty heart valve through a small cut, helping blood flow correctly. The JenaValve is a new type of heart valve implanted through a specific method.

Who is the study for?

This trial is for patients with severe aortic regurgitation, who are at high risk for traditional open-heart valve replacement surgery. They should have symptoms that affect their daily activities (NYHA class II or higher). Participants must understand the study and agree to its terms with written consent. Those with abnormal aortic valve morphology, previous valve replacements, active infections, urgent heart conditions, or severe mitral regurgitation cannot join.

What is being tested?

The ALIGN-AR EFS TRIAL is evaluating the JenaValve Pericardial TAVR System as a treatment option for severe Aortic Regurgitation. This condition causes blood to leak back into the heart chamber due to an improperly closing valve. The trial aims to gather data on this less invasive alternative to open-heart surgery.

What are the potential side effects?

While specific side effects of the JenaValve system aren't listed here, similar procedures may include risks like bleeding, blood vessel complications, irregular heartbeats, stroke, infection at the catheter site and potential need for permanent pacemaker.
