TAVR: The Impact of Prothesis Positioning on Valvular and Coronary Hemodynamics

This study is looking at how the position of an artificial heart valve placed through a catheter (a TAVR procedure — transcatheter aortic valve replacement) affects blood flow through the valve and to the coronary arteries (the arteries that supply the heart muscle). By analyzing imaging data from patients who have already had the procedure, researchers hope to learn how valve positioning can be optimized to reduce future complications. **You may be eligible if...** - You have already undergone a TAVR procedure with the valve placed through the groin (transfemoral approach) - Your medical records and imaging data are available for analysis **You may NOT be eligible if...** - Your valve was placed through a route other than the groin (e.g., through the chest or arm) - You had a valve placed inside a previously implanted bioprosthetic valve (valve-in-valve procedure) - You had a prior bioprosthetic valve implantation - You have a pacemaker, defibrillator, or cardiac resynchronization device - You have been diagnosed with significant liver disease Talk to your doctor to see if this trial is right for you.
