Could a simple CT scan replace an invasive procedure to detect dangerous heart clots?
NCT ID NCT07647939
First seen Jun 27, 2026 ยท Last updated Jun 27, 2026
Summary
This study explores whether an additional CT scan of the heart, taken right after a standard scan for lung clots, can effectively detect blood clots in the left atrial appendage (LAA) in people with atrial fibrillation. Currently, detecting these clots requires a more involved procedure called transesophageal echocardiography (TEE). The study will enroll 60 patients, half receiving an ungated CT and half a gated CT, to see how often the scans produce clear images. The results won't guide immediate treatment but could pave the way for faster, less invasive clot detection in the future.
What this could mean
Our plain-language read of the trial. This is informational only โ not medical advice or a prediction.
- Active substance
- Delayed CT scan (ungated or gated) for left atrial appendage thrombus detection
- What this could lead to
- If successful, this could allow doctors to quickly rule out dangerous blood clots using a simple CT scan, avoiding the need for a more invasive procedure.
- What could go wrong
- This is a small feasibility study with only 60 participants, so results may not apply to all patients. The extra scan may not provide clear enough images to reliably detect clots.
