Why the study?
Does multiplane transesophageal echocardiography improve the assessment of pathological regurgitation in patients with prosthetic heart valves compared to biplane transesophageal echocardiography?
Population
42 patients with pathologically regurgitant prostheses in the aortic, mitral, and tricuspid positions
Comparison
Multiplane transesophageal echocardiography vs Biplane transesophageal echocardiography
Design
Cross-sectional

Supports multiplane TEE for mitral periprosthetic regurgitation localization; hypothesis-generating and should not yet change practice.
Does multiplane transesophageal echocardiography improve the assessment of pathological regurgitation in patients with prosthetic heart valves compared to biplane transesophageal echocardiography?
Multiplane transesophageal echocardiography provides superior diagnostic accuracy compared to biplane imaging for assessing and localizing pathological prosthetic valve regurgitation.
Kupferwasser et al. (1997) studied this question.
