Less contrast, same clarity? study aims to make heart surgery prep safer

NCT ID NCT05758701

First seen Jul 01, 2026 · Last updated Jul 01, 2026

Summary

This study investigates whether using a lower dose of iodine contrast dye in CT scans can still produce high-quality images needed to plan a heart valve replacement procedure (TAVR). Normally, 100 ml of contrast is used, but reducing the dose may help avoid kidney injury and save resources. Participants scheduled for TAVR will receive a reduced contrast dose, and the images will be evaluated for diagnostic quality.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

Iodinated contrast agent (Omnipaque)

What this could lead to

If successful, this approach could reduce the amount of contrast dye needed for pre-surgery scans, lowering the risk of kidney injury and saving costs.

What could go wrong

The lower contrast dose might not produce images clear enough for safe surgical planning, and the study is limited to a specific patient group.
