Transesophageal echocardiography diagram. TEE is a semi-invasive procedure in that the probe must enter the body but does not require surgical (i.e., invasive) cutting for this procedure. Before inserting the probe, mild to moderate sedation is induced in the patient to ease the discomfort and to decrease the gag reflex.
Sonographer doing an echocardiogram of a child Echocardiogram in the parasternal long-axis view, showing a measurement of the heart's left ventricle. Health societies recommend the use of echocardiography for initial diagnosis when a change in the patient's clinical status occurs and when new data from an echocardiogram would result in the physician changing the patient's care.

Technicians may administer medication to physically active patients to assess their heart function. Cardiac sonographers also may assist transesophageal echocardiography, which involves placing a tube in the patient's esophagus to obtain ultrasound images. [citation needed]
Right heart strain can be caused by pulmonary hypertension, [3] pulmonary embolism (or PE, which itself can cause pulmonary hypertension [4]), RV infarction (a heart attack affecting the RV), chronic lung disease (such as pulmonary fibrosis), pulmonic stenosis, [5] bronchospasm, and pneumothorax.
The use of ICE is specialized and not intended for general echocardiography due to its cost and invasiveness. [1] [2] It is used as a part of a larger heart procedure. A typical use of ICE is for performing a transseptal puncture across the interatrial septum; in other words, pushing a catheter from the right atrium to the left atrium.
Indexing the left atrial volume to body surface area (volume/BSA) is recommended by the American Society of Echocardiography and the European Association of Echocardiography. The values for volume/BSA in the following table are the best validated, and are the same for both men and women.
The American Society of Echocardiography (ASE) is a professional organization of physicians, cardiac sonographers, nurses and scientists involved in echocardiography, the use of ultrasound to image the heart and vascular system. The organization was founded in 1975 and has more than 17,000 members nationally and internationally.
In the fields of cardiology and medical imaging, speckle tracking echocardiography (STE) is an echocardiographic imaging technique. It analyzes the motion of tissues in the heart by using the naturally occurring speckle pattern in the myocardium (or motion of blood when imaged by ultrasound ).
