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 three different ways to measure blockages in the left main artery of your heart: a detailed ultrasound scan, a special blood flow test, and a CT scan with computer analysis. Doctors want to know which method is most accurate and helpful for deciding whether you need surgery or a stent to open the artery.
Blockages in the left main artery are serious, and doctors need reliable ways to decide which patients truly need intervention. While some methods are well-established, newer imaging techniques like advanced ultrasound and computer-modeled blood flow analysis may be more accurate or less invasive, but they haven't been properly compared yet.

You will undergo a heart catheterization procedure where doctors insert a thin tube into your artery to perform three assessment tests: a detailed ultrasound scan of your artery, a blood flow measurement test, and analysis based on a CT scan you may have had. The entire process takes place during one or a few coordinated visits, and you will be monitored to ensure your safety throughout.
