Transthoracic Echocardiography with Doppler Tissue Imaging predicts weaning failure from mechanical ventilation: evolution of the left ventricle relaxation rate during a spontaneous breathing trial is the key factor in weaning outcome Measurement of the E/Ea ratio with TTE could predict weaning failure Transthoracic Doppler echocardiography is rapidly gaining appreciation as popular tool to measure CFR both in stenosed and normal epicardial coronary arteries (predominantly in left anterior descending coronary artery)

During a transthoracic echocardiogram (TTE), a technician obtains views of the heart by moving a small instrument called a transducer to different locations on the chest or abdominal wall. A transducer, which resembles a microphone, sends sound waves into the chest and picks up echoes that reflect off different parts of the heart An echocardiogram uses Doppler ultrasound to create an image. It is one of the most widely used tests in cardiology, and can provide a great deal of information about the size and shape of the heart, pumping capacity, and tissue damage. An echo can also help determine whether certain symptoms such as chest pain are related to heart disease An echocardiogram is one of the most common diagnostic tools cardiologists use to visualize the heart, aorta, and other blood vessels. An echocardiogram is essentially a Doppler ultrasound tool. The device emits sound waves, which bounce off the heart's structures, creating an image of the heart and/or blood vessels under examination A Doppler echocardiogram measures the speed and direction of the blood flow within the heart. It screens the four valves for leaks and other abnormalities. By assigning color to the direction of blood flow, (Color Flow Mapping), large areas of blood flow may be studied. These color flow mappings allow abnormal blood flow characteristics to be.

What is a transthoracic echocardiogram (TTE)? A TTE is a procedure used to check for problems with your heart. It will also show any problems in the blood vessels near your heart. Sound waves are sent through a handheld device placed on your chest. The sound waves show the structure and function of your heart through pictures on a monitor Doppler techniques are generally used in transthoracic and transesophageal echocardiograms. Doppler techniques can also be used to check blood flow problems and blood pressure in the arteries of your heart — which traditional ultrasound might not detect. The blood flow shown on the monitor is colorized to help your doctor pinpoint any problems Pulsed wave Doppler (with sample volume placed 1 cm proximal to the pulmonary valve) is used to quantify pulmonary regurgitation. Color Doppler is also used to study the tricuspid valve; approximately 90% of all individuals display mild tricuspid regurgitation In the recent years, the use of Doppler-echocardiography has become a standard non-invasive technique in the analysis of cardiac malformations in genetically modified mice. Therefore, normal values have to be established for the most commonly used inbred strains in whose genetic background those mutations are generated

A Doppler interrogation should state the modes used and should give both qualitative and quantitative information. Claims for contrast echocardiography services must be supported by documentation that conventional studies were inconclusive and there was a need for the contrast enhancement Doppler echocardiography. This Doppler technique is used to measure and assess the flow of blood through the heart's chambers and valves. The amount of blood pumped out with each beat is an indication of the heart's functioning. Also, Doppler can detect abnormal blood flow within the heart, which can indicate a problem with one or more of the.
