Does native tissue harmonic imaging improve endocardial border definition and visualization of cardiac structures compared to fundamental imaging mode in patients undergoing echocardiography?
Native tissue harmonic imaging significantly improves endocardial border definition, wall motion scoring, and visualization of cardiac structures compared to fundamental imaging.
Kornbluth et al. (1998) conducted an observational in Patients undergoing transthoracic echocardiograms (n=60). Native tissue harmonic imaging vs. Fundamental mode imaging was evaluated on Improvement in visualization of segments (95% CI 0.61-0.66). Native tissue harmonic imaging improved visualization in 64% of segments (95% CI 0.61-0.66) and altered wall motion scoring in 16% of segments (P<0.002 vs interobserver disagreement).
