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

This study tests whether a CT scan done to look for blood clots in the lungs can also check for a clot in the heart's left atrial appendage in people with atrial fibrillation. If successful, it could help doctors find and treat heart clots sooner.
This trial tests whether a procedure called electrical cardioversion (a controlled shock to reset your heart rhythm) can help explain and possibly improve symptoms of atrial fibrillation and heart failure. If you qualify, you'll receive this procedure and your symptoms will be closely monitored.
This trial uses a special imaging tool inside the heart to guide a new type of energy (pulsed field) to treat a specific area in the heart that can cause atrial fibrillation (an irregular heartbeat). It may help people with paroxysmal or persistent atrial fibrillation who need a procedure called CTI ablation.
This study looks at how a very fast heart rate from atrial fibrillation might affect the heart muscle. If you are having symptoms from this condition and haven't had a prior heart attack or stent, you may be able to help researchers understand the link and improve care.
This trial uses a special CT scan to measure how much extra fluid is in your heart muscle. It aims to help doctors better understand and treat your atrial fibrillation before you have a procedure called ablation.
This trial is testing whether a coronary CT angiography scan, performed before catheter ablation for atrial fibrillation, helps doctors find hidden blockages in heart arteries. It may help people without known heart disease avoid unnecessary procedures.
