Intravascular Ultrasound and Angiography in CTO Intervention

Intravascular Ultrasound (IVUS) and Angiography are imaging tools used during Chronic Total Occlusion (CTO) interventions to treat blocked coronary arteries. Angiography involves injecting dye into the blood vessels and taking X-ray images to visualize blockages' location and size. IVUS uses a tiny ultrasound probe inserted into the artery to provide detailed cross-sectional images of the vessel walls and plaque. Together, these tools help doctors accurately identify the blockage, plan the best approach to open the artery, and ensure the repair is effective, improving the chances of restoring healthy blood flow to the heart.
