Key result
Transesophageal echocardiography using an IVUS catheter in rats showed a high correlation with actual left ventricular mass (r=0.94), offering an accurate technique for serial assessment.
Why the study?
Does TEE using an IVUS catheter accurately measure LV mass and dimensions compared to transthoracic echocardiography and actual LV mass in rats?
Does TEE using an IVUS catheter accurately measure LV mass and dimensions compared to transthoracic echocardiography and actual LV mass in rats?
Effect estimate: r=0.94
Absolute Event Rate: 0.94% vs 0.88%
TEE using an IVUS catheter provides an accurate and reproducible method for assessing LV dimensions and mass in small laboratory animals like rats.

Lu et al. (1997) studied Healthy (Sprague-Dawley rats) (n=12). Transesophageal echocardiography using an intravascular ultrasound (IVUS) catheter vs. Transthoracic echocardiography and postmortem actual LV mass was evaluated on Correlation between calculated LV mass and actual LV mass (r=0.94). Transesophageal echocardiography using an IVUS catheter in rats showed a high correlation with actual left ventricular mass (r=0.94), offering an accurate technique for serial assessment.
