University of Tennessee Health Science Center, Faculty of Medicine, 1840 Medical Center Pkwy, Suite 201, Murfreesboro, TN 37129 USA.

Background: Many techniques have been developed to minimize the risk of contrast-induced nephropathy (CIN) in patients with chronic kidney disease (CKD) through drastic reductions in iodinated contrast volume and the use of intravascular ultrasound (IVUS). While some of the described techniques completely avoid contrast use and rely on transthoracic echocardiography to check for potential pericardial bleeding, this strategy may miss or delay the treatment of potentially life-threatening complications. We hereby propose the use of group II gadolinium (Gd)-based contrast agents, instead of iodinated contrast, to complement IVUS, in order to achieve the goal of zero-contrast percutaneous coronary intervention, without raising the risk of CIN.
