Ultra-Low Contrast Volume Technique for Coronary Angiography - Successful Application in Clinical Setting.

Iodinated contrast media used during cardiac catheterization predispose patients to develop contrast-induced nephropathy. Reducing contrast volumes without impairing the quality of angiographic imaging appears to be a viable solution. We present three cases of patients with chronic kidney disease in which we used an ultra-low contrast volume technique to help minimize contrast exposure risk. This technique uses an automated contrast injection system that can be used during diagnostic or coronary interventional cases and reduces the risk of iatrogenic kidney disease without compromising imaging quality.
