Correlation Between RVOT VTI Measured via a Modified Subcostal View and LVOT VTI in Critically Ill Patients.
“An RVOT VTI > 14.6 cm predicted LVOT VTI ≥ 17 cm with 80.7% sensitivity (95% CI 62.5%–92.5%) and 100% specificity (95% CI 73.5%–100%).”

TEE mid-esophageal long-axis view at 131° in a mechanically ventilated ICU patient, demonstrating left ventricular systolic dysfunction with segmental septal wall motion abnormality, mild mitral regurgitation, and significant aortic regurgitation.

Beyond the heart: transesophageal echocardiography can reveal much more than cardiac structures.
In this video, the bifurcation of the left pulmonary vein is visualized through left lung consolidation, which acts as an acoustic window and enables extra-cardiac imaging.
