Role of Intraoperative Transesophageal Echocardiography in Cardiac Surgery: an Observational Study

Aim

This study is based on the hypothesis that the routine use of transesophageal echocardiography in cardiac surgery will influence the surgical decision taken by the surgeon intra-operatively in Kasr-Alainy hospitals.

Methods

Patients were examined with intraoperative transesophageal echocardiography (TEE) before and after cardiopulmonary bypass. Complete and comprehensive intraoperative TEE examinations will be performed by TEE certified cardiac anesthesiologists. Data that will be collected from the intraoperative examination and will be compared with preoperative transthoracic echocardiography, and the surgical decision that was taken preoperatively will be revised again with the cardiothoracic surgeon before the start of surgery. Also, TEE will be used again after weaning from bypass for revision and assessment of our decision.

Results

We examined the utility of TEE in 100 patients undergoing different types of cardiac procedures in Kasr Al-Ainy hospital. This prospective clinical investigation found that the pre- and post-CPB TEE examinations influenced surgical decision making in 10% of all evaluated patients.

Conclusion

Intraoperative TEE has the potential to influence clinical decision making for cardiac surgical patients significantly. It is useful in surgical planning, guiding various hemodynamic interventions, and assessing the immediate results of surgery. Thus, IOTEE should be used routinely in all patients undergoing all types of cardiac surgeries.
