This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This trial is testing whether patients with a severely narrowed aortic valve need routine invasive heart imaging (a procedure where a thin tube is inserted into arteries) before having a valve replacement, or whether a safer non-invasive approach—using medications and existing scans—works just as well. The study will follow about 546 patients for 3 years to see which strategy leads to better health outcomes and fewer complications.
Many patients needing aortic valve replacement also have blocked heart arteries, and doctors routinely perform invasive imaging to check for these blockages. However, it's not clear whether this routine invasive procedure is truly necessary or beneficial for everyone, especially since treating the valve problem itself may reduce heart symptoms and improve blood flow without additional intervention.

You will be randomly assigned to one of two groups: either you will receive the new non-invasive approach (taking cholesterol medications without routine invasive imaging), or you will receive the standard invasive imaging before your valve replacement procedure. After your valve replacement, you will be followed for 3 years with clinic visits and health assessments to track how well you are doing and whether you experience any heart problems or other complications.
