Overview
Transesophageal echocardiography (TEE) has had a notable positive impact on both, the care and management of a patient with congenital heart disease, such as an atrial septal defect patient. TEE has been evaluated in all age groups and is determined to be safe for pediatrics and adults. Trials have shown transesophageal echocardiography to be superior in diagnosing sinus venosus ASD compared to transthoracic echocardiography.[1]
Transesophageal Echocardiography
Transesophageal echocardiography (TEE) has had a notable positive impact on both, the care and management of a patient with congenital heart disease, such as an atrial septal defect patient. TEE has been evaluated in all age groups and is determined to be safe for pediatrics and adults. Trials have shown transesophageal echocardiography to be superior in diagnosing sinus venosus ASD compared to transthoracic echocardiography.[1]
- Transesophageal echocardiography is the preferred diagnostic tool in atrial septal defect.
- To accurately diagnose the different types of atrial septal defects and associated anomalies a two-dimensional imaging of the atrial septum from different views like parasternal, apical, and subcostal views should be used.
- A color doppler along with TEE helps to demonstrate amount and directions of shunting.
- Atrial septal defects in adults could be best visualized by subcostal views with deep inspiration and high right parasternal views.
- Ideally the entire atrial septum from the orifice of the superior vena cava to the orifice of the inferior vena cava should be visualized. This helps in detecting sinus venosus defects and large ostium secundum defects that might extends up-to that area.

Advantages
TEE is a highly recommended method of imaging modality for atrial septal defect. It can provide:
- Precise identification of the location.
- Precise information regarding lesion morphology.
- Identification of:
- Number of atrial septal defects.
- Extent of surrounding atrial septal tissue.
- Location of adjacent structures.
This information allows an interventional cardiologist to determine the best method and devise for closure.[2]
Complications
- The most common complications include:
- Less common complications:
- Perforation/laceration of the oropharynx, hypopharynx, esophagus and stomach
- Arrhythmias
- Pulmonary complications
- Circulatory derangement
- Endocarditis
Supportive Trial Data
In a study done on forty one patients with clinical diagnosis of atrial septal defect, transesophageal echocardiography was able to diagnose all the patients whereas transthoracic echocardiography was only able to diagnose 80% of them. Interestingly, 3 out of the 4 undiagnosed cases with trans-thoracic echocardiography were sinus venosus ASD. Transesophageal echocardiography is recommended when an atrial septal defect is clinically suspected but cannot be visualized by transthoracic echocardiography.[1]

A preoperative transthoracic echocardiogram be performed in every patient undergoing a transesophageal echocardiogram during congenital heart surgery. The results of the TTE should be evaluated prior to the TEE.
