IVUS-FFR Accuracy for Coronary Stenosis

IVUS-FFR Online Accuracy for Coronary Stenosis What is this study testing? This study is testing a new technology called IVUS-FFR , which uses ultrasound imaging inside heart arteries (IVUS) to quickly measure whether a narrowed artery ( coronary stenosis ) is reducing blood flow. Unlike the current standard test (FFR), this new method doesn't require extra wires or medication to work. Why is this important? Many patients with heart artery narrowing need tests to decide if a stent is necessary. Current FFR tests involve inserting a pressure wire and giving medication (like adenosine) that can cause discomfort. IVUS-FFR could provide equally accurate results faster, cheaper, and more comfortably . What happens in the study? If you join: Standard heart artery imaging (angiogram) will be performed. An ultrasound probe (IVUS) will be moved through the artery to create detailed images. The new IVUS-FFR software will analyze these images immediately to estimate blood flow. For comparison, a standard FFR test (with pressure wire and medication) will also be done. All steps use existing approved devices and take \<10 extra minutes. Who can participate? Adults (≥18 years) with: Suspected or known heart artery disease At least one artery narrowing (30%-90% blocked) Excluded: Recent heart attack (\<72 hrs), severe kidney/heart failure, or pregnancy. What are the risks and benefits? Risks: Same as routine heart catheterization (bleeding, infection, artery injury). The IVUS …
