Summary

This trial tests a new way to evaluate heart valve replacements in patients with small failing valves. It uses a minimally invasive procedure to place a new valve inside the old one and compares two methods of checking how well the new valve works.

Who is the study for?
This trial is for patients with a failing surgical aortic valve who need a valve-in-valve procedure. They must have severe stenosis or regurgitation, and be suitable for the SAPIEN 3 Ultra valve. Excluded are those with non-stented valves, certain bioprostheses brands, high risk of coronary obstruction, or unable to consent.
What is being tested?
The study compares Doppler-echocardiography versus catheterization measurements in assessing heart valve performance after ViV-TAVR. It aims to determine which method gives more accurate data on the condition of the replaced valves.
What are the potential side effects?
While not directly related to side effects, there may be risks associated with both Doppler-echocardiography and invasive hemodynamic measurements such as discomfort or complications from catheter use.

Trial Design

2Treatment groups
Experimental Treatment
Group I: Invasive hemodynamic measurementsExperimental Treatment1 Intervention
Following valve implantation, further interventions will be based on invasive hemodynamic measurements (with simultaneous aortic and ventricular pressure recording).
Group II: Doppler-echocardiographyExperimental Treatment1 Intervention
Following valve implantation, further intervention will be based on Doppler-echocardiographic measurements.

Other Research
Aortic Valve Stenosis (AVS) is commonly treated through surgical aortic valve replacement (SAVR) or transcatheter aortic valve replacement (TAVR). SAVR involves open-heart surgery to replace the narrowed valve with a prosthetic one, which improves blood flow and reduces symptoms. TAVR, including Valve-in-Valve TAVR (ViV-TAVR), is a less invasive procedure where a new valve is inserted via a catheter through the blood vessels to replace a failing bioprosthetic valve. This method is particularly beneficial for high-risk patients who may not tolerate open-heart surgery. These treatments are crucial as they alleviate the obstruction caused by the stenotic valve, thereby improving cardiac function and patient quality of life.
