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

In conclusion, although conventional TEE shows good quality images, tissue HI further improves delineation of endocardial borders. This allows a better assessment of left ventricular function during cardiac surgery. Feasibility and the high-image quality of TEE HI suggest a future role of this modality for contrast echo studies of myocardial perfusion.
