CT scan to check for clots before heart shock therapy
Part of Heart & circulation clinical trials.
This trial uses a CT scan of the left atrium to check for blood clots before a procedure called cardioversion (an electric shock to restore normal heart rhythm). The goal is to see if the CT scan can safely replace other imaging methods in the emergency department, helping to speed up treatment.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 years or older
- You have symptomatic atrial fibrillation (an irregular heartbeat) that is not caused by a temporary condition like infection or thyroid problem
- Your doctor has decided you need imaging of the left atrium before cardioversion, based on standard care guidelines
- You do not need emergency cardioversion due to very low blood pressure, severe chest pain, or signs of heart failure
- You have no reason to avoid a CT scan with contrast dye, such as kidney problems (eGFR under 45), an allergy to the dye, pregnancy, or inability to hold your breath for 20 seconds

Other trials that look related to this one.
This study tests whether a special CT scan can safely detect blood clots in a small heart chamber (left atrial appendage) while also checking for lung blood clots in emergency patients with irregular heartbeat. The goal is to catch dangerous clots early using one scan instead of multiple tests.
This study uses a CT scan of the heart to measure fat around the heart (called epicardial adipose tissue) in people with and without atrial fibrillation. The goal is to see if this fat is linked to the heart rhythm problem.
This trial tests a new method using two electrical shocks to help restore a normal heart rhythm in patients with persistent atrial fibrillation (a condition where the heart's upper chambers beat irregularly). The goal is to see if this technique is safe and effective.
This study uses chest CT images to assess stroke risk in people with atrial fibrillation (AFib). You may be eligible if you have AFib, a chest CT scan, and your prior procedures do not exclude you.
This trial uses a procedure called electrical cardioversion (a controlled shock to restore a normal heart rhythm) to see if treating atrial fibrillation or atrial flutter can improve symptoms in people with heart failure. The goal is to find out if fixing the irregular heartbeat helps you breathe better, have more energy, and feel better overall.
This study compares CT scans taken before and 3 months after atrial fibrillation ablation to see how pulse-field ablation affects lung tissue compared to radiofrequency. If you had AF ablation between 2020 and 2024 with the specified techniques and have the required CT scans, you may be able to help doctors understand long-term effects.
