Echocardiography Techniques for Heart Surgery
(CM-TTE-TEE Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial compares two ultrasound techniques used during heart surgery to evaluate their effectiveness in assessing heart chamber sizes. The two methods are transthoracic echocardiography (TTE), where an ultrasound probe is placed on the chest, and transesophageal echocardiography (TEE), where a probe is inserted into the esophagus for closer images. The trial aims to determine how these techniques agree under anesthesia and how factors like breathing affect measurements. It seeks adult patients scheduled for heart surgery who have normal heart function and require ultrasound checks during surgery. Participants will undergo TTE before and after surgery and TEE during surgery, which are standard procedures.
As an unphased trial, this study provides patients the opportunity to contribute to research that may enhance heart surgery outcomes.
Do I need to stop my current medications for the trial?
The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.
What prior data suggests that these ultrasound techniques are safe for heart surgery patients?
Research has shown that both transthoracic echocardiography (TTE) and transesophageal echocardiography (TEE) are safe and commonly used during heart surgeries. TEE enhances surgical results and reduces the risk of death in patients undergoing high-risk heart surgeries by providing clear images of the heart, aiding doctors in making better decisions during surgery.
TTE involves placing an ultrasound device on the chest. It is non-invasive and a standard part of heart surgery care. Both TEE and TTE have been used safely for many years and are crucial for helping doctors understand heart conditions during surgery.
Overall, these imaging techniques are well-tolerated, with no major safety concerns reported in studies. They are considered routine and safe parts of heart surgery procedures.12345Why are researchers excited about this trial?
Researchers are excited about this trial because it compares two different ways of measuring heart chambers during cardiac surgery. Typically, transthoracic echocardiography (TTE) is used for heart imaging, but in this trial, they're also looking at transesophageal echocardiography (TEE) under anesthesia. TEE offers a closer and potentially clearer view of the heart since it's done through the esophagus, which could lead to more accurate measurements during surgery. By directly comparing TTE and TEE, the trial aims to find out if TEE provides better information for guiding surgical decisions, which could improve outcomes for patients undergoing heart surgery.
What evidence suggests that these ultrasound techniques are effective for evaluating heart chamber dimensions during surgery?
This trial will compare transesophageal echocardiography (TEE) and transthoracic echocardiography (TTE) in cardiac surgery patients. Studies have shown that TEE during heart surgery greatly aids doctors in making better decisions and is linked to improved patient outcomes, such as a lower risk of death. Research indicates that TEE provides clearer and closer images of the heart, which can be crucial during surgery. In contrast, TTE is a non-invasive method where the ultrasound device is placed on the chest. TTE remains effective and can predict changes in heart function and blood pressure. Both techniques are valuable, but TEE might offer more detailed information during surgery.12346
