[Alternative Views of Transesophageal Echocardiography in the Assessment of Aorta Structure].

Objective: To investigate the imaging views and scanning procedure of the aorta using the transesophageal echocardiography (TEE).

Methods: In accordance with the established TEE scanning process, 337 patients had their aortas scanned on four different levels, including upper, middle, lower segment of esophagus and gastric base. All parameters such as the depth of probe, imaging angle were recorded.

[Echocardiographic features of patients with anomalous left coronary artery from the pulmonary artery].

Objective: To summarize the echocardiographic features of anomalous left coronary artery from the pulmonary artery (ALCAPA).

Methods: A study was performed on 10 patients with ALCAPA retrospectively and the result was compared with coronary angiography to summarize its echocardiographic features.

Results: Of the 10 patients with ALCAPA, there were 3 cases of infantile type and 7 cases of adult type.

[Correlation between 2D and 3D echocardiography in measuring aortic annuals diameter].

Objective: To compare the results of 2D and 3D echocardiography in measuring aortic annulus diameter (AAD).

Methods: Preoperitve transesophageal echocardiography (TEE), transthoracic echocardiography (TTE) and 3D transesophageal echocardiography (RT 3D TEE) were performed on 52 patients who underwent aortic valve replacements to measure AAD. The parameters were compared between systole and diastole.
