Summary

This study aims to evaluate the diagnostic performance of the cardiovascular surgeon's visual estimation of LV function before decannulation following cardiopulmonary bypass, using TEE results as the reference standard.

Eligibility

Age: 18 Years – 75 YearsHealthy volunteers accepted
Inclusion Criteria:

* Age between 18 and 75 years
* Scheduled for elective cardiac surgery requiring cardiopulmonary bypass (CABG, valve surgery, or aortic surgery)
* ASA physical status III-IV
* Able and willing to provide written informed consent
* Suitable for intraoperative transesophageal echocardiography (TEE)

Exclusion Criteria:

* Emergency surgery
* Known severe preoperative left ventricular dysfunction (EF \< 30%)
* Significant arrhythmias (e.g., atrial fibrillation)
* Preoperative requirement for mechanical circulatory support (e.g., IABP)
* Contraindications to TEE (esophageal pathology, bleeding risk, strictures)
* Inability to provide informed consent
