Novel Application of Tissue Doppler Imaging

Tissue Doppler imaging was used with transthoracic and transesophageal echocardiography to determine its clinical usefulness beyond visualization of ventricular wall motion. Thirteen novel applications were found: acoustically difficult transthoracic studies, thrombus, mitral chordal motion, shunt detection using saline contrast, spontaneous echo contrast, intra-aortic balloon pump position and function, endocarditis (prosthetic and native), valve strands (prosthetic and native), mobile aortic atheroma, prosthetic valve motion, aortic valve motion in the presence of a calcified aortic annulus, systolic anterior motion of the mitral valve, and cardiac tumors. Tissue Doppler imaging directly affected the ability to make dificult diagnostic decisions with increased confidence and reduced the need for additional studies.
