Artificial Intelligence Versus Anesthesiologist Visual Assessment of Ejection Fraction by Transesophageal Echocardiography During Cardiac Surgery
Sponsor: Ain Shams University
Summary
This prospective observational study evaluated the reliability of a general-purpose artificial intelligence application in estimating left ventricular ejection fraction from intraoperative transesophageal echocardiography images during cardiac surgery. The artificial intelligence estimates were compared with visual assessment by two independent blinded professor anesthesiologists and with preoperative transthoracic echocardiography findings. Ejection fraction measured using M-mode and the time required for each assessment were also evaluated. The study included 93 adults undergoing elective coronary artery bypass grafting or valve surgery. The artificial intelligence assessments were performed using pseudonymized images and were not used to guide clinical decisions or patient management.

Artificial Intelligence Assessment of TEE Images
Pseudonymized end-diastolic and end-systolic frames and an M-mode recording obtained from the transgastric short-axis mid-papillary view at 0 degrees were analyzed by a general-purpose artificial intelligence application to estimate left ventricular ejection fraction. The artificial intelligence results were compared with assessments by two independent blinded professor anesthesiologists and with preoperative transthoracic echocardiography. The artificial intelligence output was used only for research and did not guide clinical management.
