Effect of harmonic imaging without contrast on image quality of transesophageal echocardiography

Am J Cardiol. 1999 Nov 1;84(9):1132-4, A11. doi: 10.1016/s0002-9149(99)00521-4.

Abstract

Harmonic imaging improves endocardial border delineation during transesophageal echocardiography when compared with conventional imaging (26% improvement vs 2% worsening; p <0.001). This allows better assessment of left ventricular function during cardiac surgery, and suggests a role of harmonic imaging for transesophageal echocardiography.
