Echocardiography

An echocardiogram or echocardiography, cardiac echo, or simply an echo is an ultrasound of the heart. It is a type of medical imaging of the heart, using a standard ultrasound or Doppler ultrasound. Is called a echocardiogram /echocardiography

Introduced by 

It was also the first ultrasound subspecialty to use intravenous contrast.

It is performed by cardiac sonography, cardiac physiologists, or physician trained in the echocardiogram.

Recognized as the father of Echocardiography, the Swedish physician Inge Edler ( 1911-2001 a graduate of Lund University was the first in his profession to apply ultrasonic pulse-echo imaging in diagnosing a cardiac disease that the acoustical physicist Floyd Firestone had to develop to detect defects in metal castings.

In, fact Edler in 1953 produced the first echocardiogram using an industrial Firestone Sperry Ultrasonic Reflectoscope.

In developing countries’ echocardiograms, edler worked with a physicist Carl hell muth hertz the son of the Nobel laureate Gustav hertz and grandnephews of Heinrich Rudolph hertz.

Function:

It is an important tool in the assessment of wall motion abnormalities in patients with the suspected cardiac nuclear disease. It is a tool that helps in reaching an early diagnosis of myocardial infarction, showing regional wall motion abnormally.

Also, it is important in treatment and follow-up in patients with heart failure by assessing ejection fraction.

Why it’s done?

Your doctor can suggest echocardiography to :

• Check for problems with the valves or chambers of your heart.
• Check if heart problems are the cause of the symptom such as shortness of breath or chest pain.
• Detect congenital heart defects before birth.
• This type of Echocardiography you have depend on the information your doctor needs.

Types of Echocardiography

There are different types of Echocardiography but some are written here :

• Stress echocardiography
• Transesophageal echocardiography
• Transthoracic echocardiography
• Doppler echocardiography

Methodology:

There are different types of methodologies used to perform echocardiography:

• Two – dimensions echocardiography
• Contract echocardiography
• Tissue Doppler imaging
• Three dimensions of echocardiography

Symptoms:

It may be done for further evaluation of signs and Symptoms that may suggest :

Atherosclerosis:

A gradual clogging of the arteries by fatty material and other substances in the bloodstream. It can lead to problems in the wall motion or pumping function of your heart.

Cardiomyopathy:

An enlargement of the heart due to thick or weak heart muscle.

Congenital heart disease:

Defects in one or more hearts structure that occur during the formation of the fetus, such as a ventricular septal defect wall between the lower 2 chambers of the hearts

Heart failure:

A condition in which the heart’s muscles become weak or stiff During heart relaxation and blood can’t be pumped efficiently.

Cardiac tumor:

A tumor of the heart may occur on the outside surface of the heart, within one or more chambers of the heart.
