Premium Imaging Techniques with Ultra-Low Contrast Angiography

Ultra-low contrast angiography is a novel technique performed in interventional cardiology and nephrology that utilizes new intravascular invasive technology and non-invasive contrast-sparing techniques. There are two types: ultra-low contrast percutaneous coronary intervention (ULC-PCI) and zero-contrast PCI. 

A primary objective of ultra-low-contrast angiography is to minimize contrast exposure and potentially use the least toxic contrast agents to reduce the risk of developing postprocedural contrast-induced nephropathy (CIN), predominantly affecting patients with baseline systemic dysfunctions.

How is Ultra-Low Contrast Angiography performed? 

Here are some techniques used during ULC angiography, including: 

• Low-osmolar contrast medium for clear imaging. 
• Intravascular ultrasound for imaging guidance and to reduce the contrast load. 
• Intravenous volume hydration reduces the contrast concentration and increases the blood flow. 
• Using small volumes of contrast dye with small catheters to improve visualization. 
• Using multiple guide wires, such as the side branch wire, the marking wire technique. 
• Using coronary calcium as the guideline to locate and trace coronary artery ostia. 
• Increase frame rates to 30 frames per second or higher for improved visualization.

Advantages of Ultra-Low Contrast Angiography

• Affordable, effective, and safe in various clinical settings. 
• Reduced the risk of contrast-induced nephropathy. 
• Minimizes the need for large volumes of contrast injections. 
• Time-efficient procedure. 
• Visualizes even subtle calcifications on the vascular wall. 
• Imaging can be performed from multiple directions. 

Clinical Indications for Ultra-Low Contrast Angiography 

• Patients with pre-existing chronic kidney disease. 
• Cardiogenic shock.
• Contrast dye anaphylaxis. 
• Complex, high-risk coronary disease. 
• Iatrogenic or spontaneous coronary dissection. 
• Chronic total occlusions.
