A paper, “Renal Function-Based Contrast Threshold Predicts Kidney Injury in Transcatheter Aortic Valve Replacement” by Sarah Gualano, MD was recently published in The Journal of the Society for Cardiovascular Angiography and Interventions (JSCAI).

Patients who undergo transcatheter aortic valve replacement may experience kidney injury from the x-ray contrast used during the procedure. Their risk is reduced if operators use less contrast. The results of the study showed that a patient-specific volume threshold based on the patient’s kidney function is a practical way to avoid the risk of kidney damage. Specifically, incorporation of thresholds of >2x and >3x eGFR into procedural planning should be considered as a quality initiative.
