Brief Summary

Image quality of intraoperative transesophageal echocardiography (TEE) tends to get worse during long hours of operations. An orogastric tube (OGT) is often inserted in the beginning of the case, and left there for intermittent suction as needed, or removed before TEE exam to prevent echoic artifacts. However, if left there, the effect of suction might be limited due to unreliable tip position of the OG tube. If removed, stomach will be distended again. We devised the OG tube attached TEE for practical suction and assessed its effect on image quality intraoperatively.

Outcome Measures

Primary Outcomes (1)

  • Image Quality Assessment Method#1: Difference in Likert Scale Before and After Suctioning

    Difference in image quality assessment by Likert scale before/after suctioning, by assessing quality of images stored before/after suctioning. Investigators categorized the quality of all acquired images on a numeric scale (the higher number means higher image quality) based on each investigator's impression (1: very poor, 2: poor, 3: acceptable, 4: good, and 5: very good). Image quality improvement was determined by increased number. Three investigators (A, B, C) assessed the quality of all TEE image sets (i.e. before and after suctioning) post hoc. The acquired numeric scales were combined, and compared before and after suctioning, and calculated how much percentage of patients had improved image quality (i.e. increase in numeric scale), same quality (i.e. same numeric scale), and worsened image quality (i.e. decrease in numeric scale)

    TEE image sets were acquired after general anesthesia induction (before suction) and after 10minutes (after suction), and the outcome was the difference in image quality. In 6-8 months, investigator C did the same analysis on the same images in one day.

Secondary Outcomes (2)

  • Reproducibility of the Left Ventricular Fraction Area Change (LV FAC) (Inter-observer)

    Images are acquired after general anesthesia induction (before suctioning) and after 10min (after suctioning)

  • Reproducibility of the Left Ventricular Fraction Area Change (LV FAC) (Intra-observer)

    6-8 months after initial images obtained during surgery
