Key result
3D TEE identifies the structural cause of acute mechanical mitral valve dysfunction unlike 2D imaging.
Why the study?
The incremental value of three-dimensional over two-dimensional transesophageal echocardiography in assessing acute dysfunction of mechanical mitral valve prostheses was not previously described.
Does three-dimensional transesophageal echocardiography improve visualization of acute mechanical mitral valve dysfunction compared to two-dimensional imaging in a patient with a bileaflet mechanical mitral valve prosthesis?

Three-dimensional transesophageal echocardiography provides incremental diagnostic value over two-dimensional imaging in identifying the mechanism of acute mechanical mitral valve dysfunction.
No takes yet. Share an insight, caveat, or question.
3D TEE may detect mechanical mitral prosthesis dysfunction missed by 2D; leaves open whether routine use improves diagnosis or outcomes.
Pattabiraman et al. (2010) studied this question. Three-dimensional transesophageal echocardiography successfully identified the structural cause of acute mechanical mitral valve dysfunction, unlike two-dimensional imaging.
