Assement of Left Ventricular Function Before Decannulation in Cardiac Surgery :Visual Estimation vs TEE
Sponsor: Ataturk University
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.
Official title: Assessment of Left Ventricular Function Before Decannulation in Cardiopulmonary Bypass Surgeries: Comparison of the Cardiac Surgeon's Visual Estimation and Transesophageal Echocardiography

Interventions
Intraoperative Left Ventricular Function Assessment
Left ventricular function will be assessed during the decannulation phase of cardiopulmonary bypass using two diagnostic methods: (1) visual estimation of ventricular contractility by the cardiac surgeon (eyeballing) and (2) objective measurement using intraoperative transesophageal echocardiography (TEE). No experimental procedure, medication, or additional intervention will be applied. Both assessments are part of standard intraoperative monitoring in cardiac surgery. Data from both methods will be collected simultaneously to compare accuracy, agreement, and diagnostic performance.
