Which are the main indications for transthoracic echocardiography?

The most common clinical indications for ordering TTE included hemodynamic assessment (29.2%) and concern for a major acute cardiovascular event (rising cardiac biomarkers, pulmonary embolism, acute coronary syndrome, heart failure, or myocarditis; 45.8%).

Why would a TTE be ordered?

Getting a transthoracic echocardiogram, or TTE, gives your doctor a good view of your overall heart health including seeing how your heart beats and checking for any heart issues.

What can be a diagnostic limitation of transthoracic echocardiography?

Inadequate imaging technique (36 cases, 65.5%) and limitation of technique (19 cases, 34.5%) were the reasons for missing anatomical findings of transthoracic echocardiography. Age at the time of echocardiography was not a significant factor affecting the accuracy.

What is the contraindications of echocardiography?

Some of the common contraindications to stress echocardiography include acute myocardial infarction within two days, severe symptomatic aortic stenosis, heart failure exacerbation, acute pericarditis, uncontrolled arrhythmias, hypertension (more than 200/110 mmHg), and unstable angina not stabilized medically.

When do we use TTE?

INDICATIONS FOR A TRANSTHORACIC ECHOCARDIOGRAPHY (TTE) FOR PEDIATRIC PATIENTS: A heart murmur (harsh murmur, diastolic murmur, or continuous murmur) present in such a way as to have a reasonable belief that congenital heart disease might be present. Chest pain upon presentation that is not obviously non-cardiac.

When do you use TEE vs TTE?

TEE is considered more sensitive for the detection of major cardiac sources of emboli such as left atrial thrombus, aortic atheroma, valve abnormalities, atrial septal abnormalities and cardiac tumours. TTE is more suited for the visualization of left ventricular thrombus.

Is TTE or TEE more accurate?

Conclusions: TEE provides higher accuracy and feasibility than TTE in the diagnosis of BAV, and it should therefore be indicated when morphological features of AVs cannot be evaluated by TTE.

Is a transthoracic echocardiogram accurate?

Conclusions: Transthoracic echocardiography using nonstandard imaging windows is accurate in comparison to TEE for measurement of the ascending aorta at multiple levels in patients with or without aortic pathology.

What is the difference between an echocardiogram and a transthoracic echocardiogram?

A traditional echocardiogram is done by putting the transducer on the surface of the chest. This is called a transthoracic echocardiogram. A transesophageal echocardiogram is done by inserting a probe with a transducer down the esophagus.

Is hypertension an indication for echo?

Although echocardiography is the second-line study in the evaluation of hypertensive patients, it gives many clues suggesting bad prognosis associated with hypertension, including increased left ventricular (LV) mass, decreased LV systolic function, impaired LV diastolic function, and increased left atrial size and …

What is difference between TTE and TEE?

When do you use TTE instead of TEE?

In most patients, TEE provides superior image quality, particularly for posterior cardiac structures which are nearer to the esophagus and less well visualized on transthoracic echocardiography as they are more distant from the anterior TTE transducer.

How accurate are echocardiogram measurements?

Echocardiography accurately detected LVEF <40% in 27 of these 36 (75%) studies. When compared to angiographic LVEF <40%, echocardiography was falsely low in 19 studies. Echocardiographic studies overestimated angiographic LVEF <40% in 9 studies.

When is an echocardiogram indicated?

Doctors might want to see an echocardiogram to investigate signs or symptoms of heart diseases, like shortness of breath, chest discomfort or swelling in the legs. They might also order an echocardiogram if something abnormal, like a heart murmur, is detected during an exam.

When do you order echo for hypertension?

Echocardiographic evaluation of LV mass and systolic and diastolic LV function is recommended in patients with hypertension suspected to have LV dysfunction or coronary artery disease (grade D).

What is the difference between transthoracic echo and transesophageal echo?

Is TTE or TEE more specific?

As compared with TTE, TEE offers superior visualization of posterior cardiac structures because of close proximity of the esophagus to the posteromedial heart with lack of intervening lung and bone. This proximity permits use of high-frequency imaging transducers that afford superior spatial resolution.

Are echocardiograms always accurate?

Echocardiograms also provide highly accurate information on heart valve function. They can be used to identify leaky or tight heart valves. While the EKG can provide clues to many of these diagnoses, the echocardiogram is considered much more accurate for heart structure and function.

Are echocardiograms 100 accurate?

Echocardiographic studies overestimated angiographic LVEF <40% in 9 studies. The sensitivity and specificity of echocardiography in assessing LVEF <40% were 75% and 89%, respectively. Moderately to severely reduced angiographic LVEF ≤35% was present in 26 of 202 (13%) studies.
