Summary
Three-dimensional speckle tracking echocardiography revealed impaired left ventricular longitudinal function immediately after coronary artery bypass grafting surgery. Global longitudinal strain is a sensitive measure for detecting acute changes in cardiac function post-CABG.
Area of Science:
- Cardiology
- Cardiac Surgery
- Medical Imaging
Background:
- Assessing early effects of coronary artery bypass grafting (CABG) on left ventricular (LV) function is crucial for improving clinical outcomes.
- Three-dimensional speckle tracking echocardiography (3D STE) can provide insights into acute changes in LV performance during surgical revascularization.
Purpose of the Study:
- To evaluate acute changes in LV performance during CABG surgery using 3D STE.
- To determine the sensitivity of various echocardiographic parameters in detecting functional changes post-CABG.
Main Methods:
- Thirty-five patients undergoing CABG had intraoperative transesophageal echocardiography (TEE) before and after surgery.
- 3D LV ejection fraction (LVEF), tissue motion annular displacement (TMAD), 3D global longitudinal strain (GLS), global circumferential strain (GCS), twist, and torsion were quantified.
- Regional longitudinal strain (LS) was assessed in relation to coronary perfusion territories.
Main Results:
- 3D GLS significantly decreased post-surgery (-18.6% to -16.0%, P=.01), while TMAD and 3D LVEF showed no significant change.
- No significant alterations were observed in GCS, twist, or torsion during the surgery.
- 3D GLS demonstrated significant correlation with 3D LVEF (r=-0.34 to -0.51, P<.05).
Conclusions:
- 3D STE enables detailed myocardial deformation evaluation, revealing impaired LV longitudinal function immediately after CABG.
- Global longitudinal strain (GLS) is more sensitive than conventional parameters for detecting acute LV functional reductions post-surgery.
- GLS may be valuable for serial monitoring of functional recovery after CABG.
