We report three-dimensional transesophageal echocardiographic findings in an adult patient with Ebstein's anomaly. Using the anyplane technique and multiple views, especially the short-axis view of tricuspid valve, three-dimensional transesophageal echocardiography clearly demonstrated the intermittent tethering of all three leaflets of tricuspid valve to the right ventricular walls giving a "bubble-like" appearance. On the other hand, two-dimensional transesophageal echocardiography demonstrated well the tethering of the septal tricuspid leaflet, but tethering of the other two leaflets was not well seen. To our knowledge, these findings have not been demonstrated by three-dimensional transesophageal echocardiography before.

Automatic 4D mitral valve segmentation from transesophageal echocardiography: a semi-supervised learning approach.

Performing automatic and standardized 4D TEE segmentation and mitral valve analysis is challenging due to the limitations of echocardiography and the scarcity of manually annotated 4D images. This work proposes a semi-supervised training strategy using pseudo labelling for MV segmentation in 4D TEE; it employs a Teacher-Student framework to ensure reliable pseudo-label generation. 120 4D TEE recordings from 60 candidates for MV repair are used.

: Valve-sparing root replacement surgery is an alternative strategy for patients with aortic regurgitation with or without aortic root enlargement. A detailed understanding of the mechanisms of regurgitation and the morphology of the aortic root would be beneficial for predicting the feasibility and success of valve-sparing surgery. This is an exploratory study of the measurement of geometric height in 3D transesophageal echocardiography as a predictor of valve-sparing root replacement for aortic regurgitation.

Potential of right ventricular function assessment with echocardiography in transcatheter aortic valve replacement.

Background: Right ventricular (RV) function assessment by echocardiography can be challenging due to its complex morphology. Also, increasing use of sedation rather than general anesthesia for transfemoral approach transcatheter aortic valve replacement (TAVR) reduces the need for intraoperative transesophageal echocardiography (TEE). Recent clinical studies have demonstrated the importance of 3-dimensional (3D) echocardiography and a longitudinal strain for RV function assessment.

Introduction: Nonbacterial thrombotic endocarditis (NBTE) is a rare cardiac manifestation in patients with advanced malignancies of the lungs, pancreas, gynecological system, and gastrointestinal tract. It is often confirmed postmortem by histopathological evidence of sterile platelet-fibrin deposits attached to the endocardium, most often on heart valves. To the best of our knowledge, our case is the first to report multiple heart lesions caused by the systemic effect of cholangiocarcinoma.
