Correlation of echocardiographic parameters in prone and supine positions in normal adults using a novel approach.

Background: Transthoracic echocardiography (TTE) in prone position is challenging. Innovative use of transesophageal echocardiography (TEE) probe to perform TTE for such patients has been described; but reproducibility and correlation of the TTE measurements by this technique with those obtained by the standard supine TTE study are still unknown.

Methods: We enrolled 30 non-COVID-19 individuals, with a mean (SD) age 35 (10.
