Cardiac MRI & Coronary CTA

Cardiac MRI & Coronary CTA – Advanced Cardiovascular Care Center

Magnetic resonance imaging (MRI) is a safe, noninvasive test provides detailed pictures of organs and tissues. MRI uses radio waves, magnets, and a computer to create pictures of your organs and tissues. MRI doesn’t use ionizing radiation or carry any risk of causing cancer.

 Cardiac MRI Scan report provides both structure and moving pictures of the heart and major blood vessels. Doctors use cardiac MRI to get images of the beating heart and to look at its structure and function. These pictures can help them decide the best way to treat patients who have heart problems.

 Cardiac MRI is a common test. It’s used to diagnose and assess many diseases and conditions, including:

  • Coronary heart disease
  • Damage caused by a heart attack
  • Heart failure
  • Heart valve problems
  • Congenital heart defects
  • Cardiac tumors

 Cardiac MRI can help explain results from other tests, such as X-rays and computed tomography scans also called CT scans. Doctors sometimes use cardiac MRI instead of invasive procedures or tests that involve radiation or dyes containing iodine.

 A contrast agent, such as gadolinium, might be injected into a vein during cardiac MRI. The substance travels to the heart and highlights the heart and blood vessels on the MRI pictures. This contrast agent often is used for people who are allergic to the dyes used in CT scanning. People who have severe kidney or liver problems may not be able to have the contrast agent. As a result, they may have a non-contrast MRI.

 Cardiac MRI (Magnetic Resonance Imaging) allows cardiologists to see the heart in more detail than any other imaging format available. It is a non-invasive treatment that can more accurately identify in need of coronary angiography, coronary stenting or bypass operations. A cardiac MRI is a non-invasive test that uses radio waves to take images of the heart. Doctors use the test to evaluate the structure and function of the heart and blood vessels. Cardiac MRI test usually takes 45-90 minutes and it doesn’t hurt.

Coronary CTA is used as a noninvasive method for detecting blockages in the coronary arteries. A CTA can be performed much faster (in less than one minute) than a cardiac catheterization, with potentially less risk and discomfort as well as decreased recovery time.

 A coronary computed tomography angiogram (CCTA) uses advanced CT technology, along with intravenous (IV) contrast material (dye), to obtain high-resolution, 3D pictures of the moving heart and great vessels.

 Coronary CTA is also called multi-slice computed tomography (MSCT), cardiac CT or cardiac CAT. During CTA, X-rays pass through the body and are picked up by detectors in the scanner that produce 3D images on a computer screen. These images enable physicians to determine whether plaque or calcium deposits are present in the artery walls.

 Coronary CTA (CCTA) allows direct visualization of the coronary artery wall and lumen with the administration of intravenous contrast. Coronary Computed Tomography Angiogram (CTA) technology results in structure of the functioning of heart.  Coronary CTA test can provide important insights to their primary physician into the extent and nature of plaque formation with or without any narrowing of the coronary arteries.

 Who should have a Coronary CTA Test?

Intermediate to high-risk profiles for coronary artery disease, but who do not have typical symptoms especially chest pain, shortness of breath, or fatigue during heavy physical activity.

  • Unusual symptoms for coronary artery disease, but low to intermediate risk profiles for coronary artery disease
  • Unclear or conclusive stress-test (treadmill test) results

 Get tested by Cardiac MRI/Coronary CTA scans to identify the imaging of the complete cardiovascular system.

Hypertrophic cardiomyopathy (HCM)

Hypertrophic cardiomyopathy (HCM) is a disease in which the heart muscle (myocardium) becomes abnormally thick (hypertrophied). The thickened heart muscle can make it harder for the heart to pump blood. Hypertrophic cardiomyopathy is very common and can affect people of any age. About one out of every 500 people has HCM. It affects men and women equally.

Other Names for Hypertrophic Cardiomyopathy

  • Asymmetric Septal Hypertrophy
  • Familial Hypertrophic Cardiomyopathy
  • Hypertrophic Obstructive Cardiomyopathy
  • Hypertrophic Non-obstructive Cardiomyopathy
  • Idiopathic Hypertrophic Sub-aortic Stenosis (IHSS)

Causes of Hypertrophic Cardiomyopathy:

HCM is a genetic condition caused by a change or mutation in one or more genes and is passed on through families. Each child of someone with HCM has a 50 per cent chance of inheriting the condition. HCM is a common cause of sudden cardiac arrest (SCA) in young people, including young athletes.

HCM also can affect the heart’s mitral valve, causing blood to leak backward through the valve. Sometimes, the thickened heart muscle doesn’t block blood flow out of the left ventricle. This is called non-obstructive hypertrophic cardiomyopathy. The entire ventricle may thicken, or the thickening may happen only at the bottom of the heart. The right ventricle also may be affected.

Symptoms of HCM:

Many people with HCM don’t experience any symptoms. However, the following symptoms may occur during physical activity:

You may find that you never have any serious problems related to your condition, and with treatment, your symptoms should be controlled. However some people may find that their symptoms worsen or become harder to control in later life.

The area of heart muscle that is affected by HCM and the amount of stiffening that occurs will determine how the symptoms affect you.

For some people, a number of other conditions can develop as a result of having HCM. These may include abnormal heart rhythms, or arrhythmias, including heart block and endocarditis.

Other symptoms that might occur, at any time, include:

  • Chest pain
  • Palpitations
  • Shortness of breath
  • High blood pressure
  • Light headedness and fainting

 

Diagnosis of Hypertrophic Cardiomyopathy:

The health care provider will perform a physical exam and listen to the heart and lungs with a stethoscope. Signs may include abnormal heart sounds or a heart murmur. These sounds may change with different body positions, High blood pressure, the pulse in your arms and neck will also be checked. The doctor may feel an abnormal heartbeat in the chest.

Close family members of people who have been diagnosed with hypertrophic cardiomyopathy may be screened for the condition. Tests used to diagnose heart muscle thickness, problems with blood flow, or leaky heart valves (mitral valve regurgitation) may include:

  • Echocardiography, ECG
  • Cardiac catheterization
  • MRI of the heart, Chest X-ray
  • Transesophageal echocardiogram (TEE)
  • 24-hour Holter monitor (heart rhythm monitor)

Risk Factors include:

Any strenuous exercise that increases after load (i.e., heavy weight lifting/training) can theoretically increase the magnitude of LV hypertrophy over time and thus worsen obstruction in subjects with pre-existing HCM. Risk factors for the development of end-stage HCM (manifesting as LV systolic dysfunction and LV dilation) include younger age of onset/presentation of HCM, a family history of HCM, increased ventricular wall thickness, along with the presence of certain genetic mutations in certain individuals.

Treatment of HCM:

At present there is no cure for HCM, but treatments are available to help control your symptoms and prevent complications. Your treatment will depend on how your heart is affected and what symptoms you have. You may need:

  • A Pacemaker – to control your heart rate
  • Medicines – to help control your blood pressure, abnormal heart rhythms
  • An ICD – if you are at risk of having a life threatening abnormal heart rhythm

Seek counsel from our Houston Cardiologist if you suspect you are suffering from Hypertrophic Cardiomyopathy (HCM) for the best treatment options for you.
