CT Coronary Angiogram

Introduction
A CT Coronary Angiogram is performed to visualize the heart, blood vessels, and surrounding tissues. The test involves injecting a dye through a catheter. The dye highlights the blood vessels and aids in obtaining a clear image of the peripheral vein, arteries and tissues. A CT coronary angiogram utilizes an X-ray machine to produce images of the heart and surrounding arteries. It is a Non-Invasive Cardiac Imaging procedure that does not require recovery time.

 

Why is CT Coronary Angiogram Done?

Cardiac CT Angiography is performed to identify constricted heart arteries, but it can also detect other heart issues. In the traditional method (non-CT angiography), a flexible tube called a catheter is inserted either through the groin or wrist to access the heart and coronary arteries. The conventional method can also serve as a treatment for individuals already diagnosed with coronary artery disease. It is important to note that CT coronary angiography is distinct from the traditional angiogram. Its primary purpose is to diagnose the following conditions:

 

  • Irregular bulges, aneurysms, and wide bulges in the blood vessels.
  • Coronary artery disease.
  • Pulmonary embolism.
  • Fatty plaque deposits inside the blood vessels

How is CT Coronary Angiogram Done at Hinduja Hospital?

CT Coronary Angiogram in Mumbai is typically done to assess the condition of the heart. During the consultation, our doctor will provide all the necessary information regarding specific do's and don'ts before and during the procedure. The doctor advises abstaining from eating anything for 4 hours prior to the test. Additionally, consuming any beverages or soft drinks is also prohibited, but water is allowed. Moreover, it is strictly prohibited to consume beverages containing caffeine, as it can elevate the heart rate, leading to false readings and inaccurate reports.

Before the Procedure

Before the Cardiac CT Angiography, the individual will be requested to remove all jewelry, hairpins, dentures, eyeglasses, and any other items. Doctors administer beta blockers to enhance the clarity of the image of the heart, blood vessels, and surrounding tissues. Therefore, it is important to inform the doctor if the person has experienced any side effects or complications from beta blocker medication. Additionally, if the individual has titanium or any other implants, they should discuss this during the consultation.

During the Procedure

During the CT Angiogram Procedure, the healthcare provider will insert an IV. Prior to this, they will numb the area. Once the IV is inserted, a dye will be injected through it, aiding in obtaining clearer and better images on the Cardiac CT Scan. Additionally, electrodes will be placed on the person's chest to record the heart rate. Subsequently, the person will be positioned on a table that moves through a tunnel-like machine (CT scan machine). Throughout the process, it is crucial to remain still, and the person may be required to hold their breath, as even slight movement can result in blurry images.

While the imaging process typically lasts 5-10 minutes, the entire procedure usually takes hours. Therefore, it is advised for patients visiting the clinic to schedule the test with ample time available.

Note: If a person experiences discomfort in confined spaces, it is advisable to inform the doctors immediately. They may prescribe medication for relaxation.

After the Procedure

There isn't much to do after a CT Angiogram Procedure. The person can resume their normal activities. However, it is important to drink plenty of water to flush out the dye from the body. Once the test results are available, the clinic will contact the patient and provide them with the report.

If the results suggest that the person has or is at risk of having heart disease, they will be promptly referred to a heart specialist to discuss treatment options.

Is There Any Risk of a CT Coronary Angiogram?

There are fewer to no risks associated with a CT Coronary Angiogram procedure in Mumbai. However, the usage of dye and radiation may cause some complications.

Dye - The dyes used for Cardiac CT Scan contain iodine, which can trigger allergies in some individuals. The kidneys eliminate the iodine from the body, and if they have been damaged by disease or infection such as diabetes, the person might need to drink more fluids after the test to assist in the elimination of the dye. However, modern dyes used for the tests pose a significantly lower risk to the kidneys. Allergic reactions to the dye can range from mild to severe, so if a person experiences any of the following symptoms, they should inform the doctor:

  •     Mild reactions include itching and skin flushing.
  •     Severe reactions may manifest as a skin rash or hives, heart arrest, breathing difficulties, or dehydration.

Radiation -

There is some radiation exposure associated with any X-ray, including a CT coronary angiogram. This is a significant concern for pregnant women and women who are trying to conceive, although it is generally considered harmless. The radiation levels during the test are deemed safe.

Who is Not a Good Candidate for CT Coronary Angiogram?

Elderly individuals should avoid undergoing a CT coronary angiogram until advised for people with these health conditions, doctors typically recommend alternative tests. Additionally, pregnant women should inform their doctors, as in such cases, only a minimal amount of radiation will be used, ensuring the safety of both the fetus and the mother.

Conclusion

Coronary Artery Imaging is done to assess the condition of the blood vessels and tissues. It is a less invasive procedure widely used for heart disease diagnosis. Although the test itself is non-invasive, there are a few precautions that individuals must take. For instance, it is important to determine if there is an iodine allergy as the test involves the use of dye containing iodine. When selecting a hospital or clinic for the procedure, it is crucial to ensure that the facility utilizes the latest technology.
