ACURATE IDE: Safety and Effectiveness Study of ACURATE Valve for Transcatheter Aortic Valve Replacement

To be considered for a study like this, certain health conditions or features would typically need to be present. For this study, you would have needed to have a severe narrowing of your aortic valve, diagnosed by heart scans like an echocardiogram. This narrowing would have caused noticeable symptoms like breathlessness or tiredness, falling into a certain category of heart failure symptoms (NYHA Functional Class II or worse).

Additionally, your heart doctor and heart surgeon would both need to agree that replacing your aortic valve using the minimally invasive TAVR procedure was the right treatment for you and that you would likely benefit from it. Your heart's main valve, the aortic annulus, would also need to be a specific size to fit the study's valves. You also needed to be able to understand the study, agree to participate, and come back for all your follow-up appointments. You would also need to be able to take any necessary medicines prescribed as part of the study.

However, there were certain reasons you couldn't join. For example, if you had an aortic valve with only one or two leaflets instead of the usual three, or if you had recently had a heart attack within the last month, you wouldn't have been eligible.

If you had joined this study, you would have been carefully assessed to ensure the study was right for you. Your journey might have involved being in a group where you received the ACURATE valve, or a group receiving one of the other established valves, decided randomly, like tossing a coin. You would have had several visits to the hospital for assessments before and after your valve replacement procedure.

Some parts of the study involved closer monitoring. For example, some participants had special 4D CT scans (a detailed type of X-ray) to look very closely at the new valve and how it was working. There was also a smaller group for a different version of the ACURATE valve. All participants would have been asked to take specific medications as directed by the study doctors. You would have been asked to return to the hospital for scheduled follow-up visits after your procedure to check on your health and how the new valve was performing over time. The overall duration of your participation would have depended on the study's follow-up schedule.
