What to Expect During a Heart CT Scan for CHD

If you or a loved one has been diagnosed with a congenital heart disease (CHD), the thought of undergoing a Heart CT scan / Cardiac CT can be overwhelming. At KidsHeart Medical Center, we are committed to ensuring that our patients in Abu Dhabi and Dubai are well-informed and comfortable throughout their medical journey. This blog aims to provide a comprehensive guide on what to expect before, during, and after a cardiac CT scan for CHD in adults. Understanding the process can help alleviate anxiety and ensure that you are prepared for each step.

What is a Cardiac CT Scan?

A cardiac CT (Computed Tomography) scan is a non-invasive imaging procedure that provides detailed 3D pictures of the heart and its blood vessels. This advanced technology helps doctors diagnose and manage congenital heart diseases with precision. The scan involves using X-rays and computer technology to create cross-sectional images of the heart, which can reveal structural abnormalities, blockages, and other issues that might not be visible with traditional imaging methods.

Why is a Cardiac CT Scan Necessary?

For adults with congenital heart diseases, a cardiac CT scan is crucial for several reasons:

• Detailed Visualisation: It provides a clear and detailed image of the heart’s structure including the coronary arteries , helping in the accurate diagnosis of CHD.
• Non-Invasive: Unlike traditional angiography, a cardiac CT is less invasive and does not require a catheter to be inserted into the heart.
• Early Detection: Early and accurate detection of potential issues allows for better management and treatment planning.
• Pre-Surgical Planning: It aids surgeons in planning complex procedures by providing a detailed map of the heart’s anatomy as well as surrounding structures .

Before the Heart CT Scan

Consultation and Preparation

1. Initial Consultation: Your journey begins with a consultation with Dr. Salwa Morcos Gendi or one of our experienced cardiologists. During this session, your medical history will be reviewed, and the necessity of a cardiac CT scan will be explained.
2. Pre-Scan Instructions: You will receive specific instructions on how to prepare for the scan. This may include fasting for a few hours before the procedure and avoiding certain medications. It’s essential to follow these guidelines to ensure the accuracy of the results.
3. Allergy Check: Inform your doctor if you have any allergies, especially to iodine or contrast dyes, as these are commonly used during the scan.
4. Kidney function by blood test
5. Medication Adjustment: If you are taking medications, particularly those affecting heart rate, your doctor might adjust your dosage to optimize the scan results.
6. Health Status Confirmation: Ensure that any existing conditions, such as asthma or diabetes, are under control. Your doctor might recommend additional tests or adjustments to your treatment plan if needed.

Mental and Emotional Preparation

Undergoing a medical procedure can be stressful. Here are a few tips to help ease your mind:

1. Education: Understanding the procedure can reduce anxiety. Don’t hesitate to ask questions during your consultation.
2. Relaxation Techniques: Practice deep breathing, meditation, or other relaxation techniques in the days leading up to your scan.
3. Support System: Arrange for a family member or friend to accompany you to the appointment for emotional support.

During the Cardiac CT Scan

Arrival at the Medical Center:

1. Check-In Process: On the day of your scan, arrive at KidsHeart Medical Center a bit earlier to complete any necessary paperwork and check-in procedures.
2. Comfortable Attire: Wear comfortable clothing, and you may be asked to change into a hospital gown.

The Procedure

1. Positioning: You will lie down on a motorized table that slides into the CT scanner, a large machine with a circular opening.
2. Electrode Placement: Electrodes will be attached to your chest to monitor your heart rate throughout the scan. This helps synchronize the images with your heartbeats.
3. Contrast Injection: A contrast dye may be injected into your vein to enhance the images. You might feel a warm sensation or a metallic taste in your mouth, which is normal and temporary.
4. Breathing Instructions: You will be asked to hold your breath for short periods during the scan to ensure clear images. The technician will guide you through these instructions.
5. Imaging Process: The table will move slowly through the scanner as it takes images. The entire process typically takes around 10 to 20 minutes.

Safety and Comfort

1. Radiation Exposure: The amount of radiation used in a cardiac CT scan is relatively low, but inform your doctor if you are pregnant or suspect you might be.
2. Communication: You can communicate with the technician at any time during the scan. If you feel uncomfortable, let them know.

After the Cardiac CT Scan

Immediate Post-Scan Steps

1. Observation: You might be asked to stay for a short period after the scan for observation, especially if you received a contrast dye.
2. Hydration: Drink plenty of fluids to help flush the contrast dye out of your system.
3. Normal Activities: In most cases, you can resume your normal activities immediately after the scan.

Receiving Results

• Analysis by Specialists: The images from your cardiac CT scan will be analyzed by Dr. Gendi and her team. This may take a few days.
