Pulmonary Valve Stenosis : Tests

The health care provider may hear a heart murmur by stethoscope. Tests used in the diagnosis of pulmonary stenosis may include: Cardiac catheterization; Chest x-ray; ECG; Echocardiogram; MRI of the heart.

Pulmonary valve stenosis is a congenital heart defect in which blood flow from the heart to the pulmonary artery is blocked.

Cardiac catheterization involves passing a catheter (a thin flexible tube) into the right or left side of the heart. In general, this procedure is performed to obtain diagnostic information about the heart or its blood vessels or to provide treatment in certain types of heart conditions. Cardiac catheterization can be used to determine pressure and blood flow in the heart's chambers, collect blood samples from the heart, and examine the arteries of the heart with an x-ray technique called fluoroscopy. Fluoroscopy provides immediate ("real-time) visualization of the x-ray images on a screen and provides a permanent record of the procedure.

Cardiac catheterization (also called heart catheterization) is a diagnostic procedure which does a comprehensive examination of how the heart and its blood vessels function. One or more catheters is inserted through a peripheral blood vessel in the arm (antecubital artery or vein) or leg (femoral artery or vein) with x-ray guidance.

You may have had angina, dizziness, or other symptoms of heart trouble. To help diagnose your problem, your doctor may suggest having a cardiac catheterization. This common procedure is sometimes also used to treat a heart problem.

Cardiac catheterization (also called heart catheterization) is a diagnostic and occasionally therapeutic procedure that allows a comprehensive examination of the heart and surrounding blood vessels . It enables the physician to take angiograms, record blood flow, calculate cardiac output and vascular resistance, perform an endomyocardial biopsy, and evaluate the heart's electrical activity.

Echocardiogram is a test that uses sound waves to create a moving picture of the heart. The picture is much more detailed than x-ray image and involves no radiation exposure.

Echocardiography is a diagnostic test that uses ultrasound waves to create an image of the heart muscle. Ultrasound waves that rebound or echo off the heart can show the size, shape, and movement of the heart ' s valves and chambers as well as the flow of blood through the heart.

An echocardiogram (echo) is an imaging test. It helps your doctor evaluate your heart. Here is how it works.

Echocardiography is a diagnostic test that uses ultrasound waves to produce an image of the heart muscle and the heart ' s valves. Purpose Echocardiography is used to diagnose certain cardiovascular diseases, and is one of the most widely used diagnostic tests for heart disease.

A chest x-ray is an x-ray of the chest, lungs, heart, large arteries, ribs, and diaphragm.

A chest x ray is a procedure used to evaluate organs and structures within the chest for symptoms of disease. Chest x rays include views of the lungs, heart, small portions of the gastrointestinal tract, thyroid gland and the bones of the chest area.

Coronary angiography is a procedure that uses a special dye (contrast material) and x-rays to see how blood flows through your heart.

Angiography is a special type of x-ray that allows your coronary arteries to be viewed and recorded on film. Your doctor can see if the blood vessels to your heart are clogged.

Computed Tomography Angiography (CTA)CTAcreates images of arteries throughout the body. Acontrast medium(x-ray dye) is injected to make the blood vessels stand out.

Angiography is the x-ray (radiographic) study of the blood vessels. An angiogram uses a radiopaque substance, or contrast medium, to make the blood vessels visible under x ray.

An electrocardiogram (ECG) is a test that records the electrical activity of the heart. ECG is used to measure the rate and regularity of heartbeats as well as the size and position of the chambers, the presence of any damage to the heart, and the effects of drugs or devices used to regulate the heart (such as a pacemaker. See also stress test and Holter monitor (24h.

The electrocardiogram (ECG) displays important information about the heart, including the occurrence of a heart attack or lack of oxygen, whether conduction of the heartbeat is disturbed, or its rate or rhythm altered. It is useful as a rapid indicator of the diagnosis and it is easy, painless, and inexpensive to record.

Electrocardiography is a commonly used, noninvasive procedure for recording electrical changes in the heart. The record, which is called an electrocardiogram (ECG or EKG), shows the series of waves that relate to the electrical impulses that occur during each beat of the heart.

Did you know that electrical currents flow throughout your body? Because the strongest of these travels through your heart, doctors are able to monitor your heart by placing electrical sensors on the surface of your skin. They do this by giving you an electrocardiogram -- abbreviated either ECG or EKG (from the original German spelling of the word).

The ECG (also known as EKG) is a test that records electrical signals from your heart onto a paper strip. The pattern of these signals can tell the doctor whether your heart is normal, under stress, or experiencing electrical problems, strain, or damage.

The Harvard Health Letter celebrates its 30th anniversary this year. In the first of a series, the Health Letter takes a look back at three decades in medicine.

During a physical examination, a health care provider studies a patient's body to determine the presence or absence of physical problems. A typical physical examination includes: Inspection (looking at the body; Palpation (feeling the body with hands; Auscultation (listening to sounds; Percussion (producing sounds.

A chest MRI uses powerful magnets and radio waves to create pictures of the body. Conventional radiography and computed tomographic (CT) imaging use potentially harmful radiation (x-rays) that passes through a patient to generate images. Magnetic resonance imaging (MRI) is based on the magnetic properties of atoms, and there is no exposure to the same type of radiation used in x-rays and CT scans. A powerful magnet generates a magnetic field roughly 10,000 times stronger than the Earth's. A very small percentage of hydrogen atoms within the body will align with this field. Radio wave pulses are broadcast towards the aligned hydrogen atoms in tissues of interest, returning a signal of their own. The slight differences of those signals from different tissues enables MRI to tell the difference between various organs, and potentially, provide contrast between benign and malignant tissue. Any imaging angle, or "slice", can be projected, and then stored in a computer or printed on film. MRI can easily be performed through clothing and bones. However, certain types of metal in or around the area of interest can cause significant errors in the reconstructed images.

The pulse oximeter is a photoelectric instrument for measuring oxygen saturation of the blood . A pulse oximeter uses infrared light and a photo sensor to detect the amount of oxygen in a patient's blood.

The pulse oximeter is a photoelectric instrument for measuring oxygen saturation of blood. Purpose A pulse oximeter measures the amount of oxygen present in blood by registering pulsations within an arteriolar bed (an area between arteries and capillaries).

Transesophageal echocardiography is a diagnostic test using an ultrasound device that is passed into the esophagus of the patient to create a clear image of the heart muscle and other parts of the heart. A tube with a device called a transducer is passed down into the patient ' s throat and into the esophagus (the food tube that connects the mouth to the stomach).

Transesophageal echocardiography (TEE) is a test that allows your doctor to record images of your heart from inside your esophagus, or food pipe.

Transesophageal echocardiography (TEE) is a diagnostic test in which an endoscope with an ultrasound transducer at its tip is inserted into the patient ' s esophagus by means of a catheter (thin tube). Sound waves are transmitted and received by the transducer to produce a clear image of the heart muscle and other parts of the heart.
