Using a simplified echocardiography technique during high-risk heart surgeries
Establishment and Verification of Clinical Thinking Flowchart of Rescue Transesophageal Echocardiography in the Diagnosis and Treatment of Perioperative Patients in Intensive and Critical Status
This study is testing a simpler way to use echocardiography during risky heart surgeries to see if it helps doctors find heart problems more effectively than the usual method.

What this trial studies
This study evaluates the diagnostic efficiency of a simplified transesophageal echocardiography (TEE) sequence called PReTEE, which combines three specific views to identify cardiac pathologies during challenging cardiopulmonary bypass separations in high-risk cardiac surgery patients. The trial involves junior TEE operators who will be randomly assigned to either the PReTEE group or a conventional TEE group. A total of 46 TEE examinations will be conducted, with each patient being assessed by multiple operators to ensure comprehensive evaluation. The goal is to determine if the simplified approach improves diagnostic outcomes compared to traditional methods.
Who should consider this trial
Good fit: Ideal candidates are adults aged 18 and older undergoing high-risk cardiac surgeries with specific cardiac conditions.
Not a fit: Patients with esophageal pathologies or those requiring non-elective cardiac procedures may not benefit from this study.
Why it matters
Potential benefit: If successful, this approach could enhance the accuracy of cardiac assessments during critical surgical procedures, potentially improving patient outcomes.
How similar studies have performed: While similar approaches have been explored, this specific simplified technique is novel and has not been extensively tested in prior studies.
