ABOUT APOLLO TRIAL


Learn more about symptomatic mitral regurgitation (MR), the trial design, and the Intrepid™ Transcatheter Mitral Valve Replacement (TMVR) implant procedure.

CAUTION: The Intrepid™ Transcatheter Mitral Valve Replacement System is an investigational device. Limited by federal (United States) law to investigational use. Exclusively for clinical investigations. Not approved by FDA and not for sale in the United States.

What is the APOLLO Trial?

The APOLLO Trial is studying the safety and efficacy of an investigative device called the Intrepid Transcatheter Mitral Valve Replacement System.

The Intrepid device is a heart valve that is designed to help alleviate mitral regurgitation so that blood can flow through your heart in the intended direction.

WHat is Mitral regurgitation?

Your heart has four valves that move blood in and out of its four chambers. One of the valves is a mitral valve. When a mitral valve is functioning normally, it regulates blood flow from the upper chamber (left atrium) of your heart to the lower chamber of your heart (left ventricle). However, when the mitral valve is diseased, it may not close tightly and blood can leak back into the left atrium, where it came from. This is known as a "leaky valve" or mitral regurgitation (MR). The APOLLO Trial is investigating a therapy option for mitral regurgitation.

CURRENT TREATMENT OPTIONS

Depending on the severity of MR, current treatment options may include:

  • Lifestyle changes
  • Medication
  • Mitral valve repair
  • Mitral valve replacement

Today mitral valve replacement requires surgery. Medtronic is conducting a clinical trial of an investigational, potentially less-invasive catheter-based alternative:transcatheter mitral valve replacement (TMVR).

  5. Left ventricle

THE TMVR PROCEDURE

This is a procedure that will require you to be in the hospital. Your doctor will begin by giving you some anesthesia. Your doctor will then place a tube (also called a catheter) with the Intrepid device inside of it into your heart through an incision made in a space between your ribs. Using ultrasound and x-ray images, they will guide the catheter to your mitral valve, insert the Intrepid valve there, and remove the catheter. The Intrepid valve will stay in your heart and replaces your diseased mitral valve.

After the Procedure

After your heart procedure, plan to stay in the hospital for a short time. Once your doctor releases you, expect several follow-up appointments each year. Expect to have this type of appointment for at least five years, so your doctor can continue to monitor how you feel.

Potential Risks

The risks of joining this trial are similar to the risks with other heart surgeries (these other surgeries have names like standard mitral valve surgery, repair, and replacement).

These risks could include:

  • Cardiac damage
  • Complications from surgery
  • Bleeding or infection
  • Death

For a full list of risks, speak with your doctor.
