Overview
A mapping cardiac CT, sometimes abbreviated as a coronary CT, is a non-invasive imaging test that uses x-rays to create images of the heart. These images are then used to help guide our cardiac clinical electrophysiologists (EPs) with procedures, such as atrial fibrillation ablations and atrial flutter ablations, by providing a three-dimensional map of the anatomy of the heart.
Everything You Need To Know
- Why It's Done
-
This test helps provide a map of the anatomy of the heart. The data from this test is integrated into the mapping software that is used during an ablation to visualize the anatomy of the heart.
- Where Is This Test Performed?
-
We offer this test at AdventHealth Shawnee Mission and AdventHealth Lenexa City Center. Please arrive 30 minutes before your test is scheduled to allow for check in. The procedure will take approximately 60 minutes.
- Preparations
-
No specific preparations are needed for this test. You will not need to hold any of your medications, and you do not need to be fasting for this test. You will be able to drive yourself home after the test is done and there are no restrictions afterwards.
Additional instructions
- Don’t wear undergarments with wires.
- Wear comfortable clothing, preferably with a short-sleeved t-shirt.
- During And After The Procedure
-
A radiology technician in the radiology department will insert an IV line in your hand or arm to inject the contrast dye. You will lie on a table that slides into a short, tunnel-like machine. During the scan you will be asked to hold still and do breath holds to not blur the image. The technician will operate the scanner from an adjacent room separated by a glass window but will be able to communicate with you through an intercom system.
Your Results
The mapping CT will be reviewed and read by one of our board-certified cardiologists. The data is automatically transferred for use during your atrial fibrillation/flutter ablation.
