Comparing Cardiac Chamber Measurements: TTE vs. TEE Under Anesthesia

NCT06715371 · Status: RECRUITING · Type: OBSERVATIONAL · Enrollment: 114

No results posted yet for this study

Summary

This study aims to compare two common ultrasound techniques used during heart surgery: transthoracic echocardiography (TTE) and transesophageal echocardiography (TEE). TTE is performed by placing an ultrasound probe on the chest, while TEE involves inserting a probe into the esophagus, which provides closer and clearer images of the heart. Both methods are part of routine care for patients undergoing heart surgery.

The goal of this study is to assess how well the measurements from TTE and TEE agree in evaluating heart chamber dimensions during surgery and to investigate how factors such as anesthesia, breathing techniques affect these measurements.

This research involves 114 adult patients scheduled for heart surgery at Sunnybrook Health Sciences Centre. Participants will have TTE performed before and after surgery, and TEE will be conducted during surgery. All procedures are part of the usual standard of care.

By comparing these imaging techniques, the study seeks to provide more accurate and up-to-date guidelines for cardiac measurements, ensuring better care for patients during heart surgery.

Transthoracic Echocardiography (TTE) and Transesophageal Echocardiography (TEE)

Transthoracic echocardiography (TTE) is a non-invasive imaging technique performed by placing an ultrasound transducer on the chest to obtain detailed heart images. TTE is conducted preoperatively on awake patients within two weeks prior to cardiac surgery, following ASE chamber quantification guidelines. Transesophageal echocardiography (TEE) is an invasive imaging technique where an ultrasound transducer is placed in the esophagus, providing closer and clearer images of the heart. TEE is performed intraoperatively under general anesthesia as part of routine care.
