Abstract
Introduction Left ventricular chamber size and functional assessment by transesophageal echocardiography can be difficult if visualization is poor in the mid-esophageal views. However, the accuracy of using the Simpson’s method in the transgastric 2-chamber (TG2C) as an alternative approach has not been assessed. Methods The Simpson’s method was performed by 2 independent reviewers using midesophageal 2-chamber (ME2C) and TG2C views. Echocardiographic images were retrieved retrospectively for 49 adult cardiac surgical patients. Results Two-way random effects intraclass correlation coefficients demonstrated no significant interobserver variability. Linear mixed effects models showed no significant differences in ME2C and TG2C measurements with regard to EDV (P=.4407), ESV (P=.5113), or EF (P=.0610). Compared to the ME2C view, the TG2C view had better image quality of the LV walls (image quality score median [interquartile range]: 2.00 [.00] vs 1.00 [1.00]; P<.0001), but worse image quality of the mitral annulus (1.00 [1.00] vs 2.00 [.00]; P<.0001) and LV apex (.00 [1.00] vs 2.00 [1.00]; P<.0001). Conclusions This study suggests the Simpson’s method can be applied to the TG2C view as an alternative to the standard midesophageal method to estimate chamber volumes and EF.
期刊介绍:
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
