During coronary artery bypass surgery, doctors need to know whether your heart will benefit from extra fluid. This trial tests whether a simple ultrasound measurement—called the superior vena cava collapsibility index—taken during your surgery can accurately predict this. The measurement is painless and uses an ultrasound camera already placed in your esophagus during surgery for routine monitoring.
Currently, doctors don't have a reliable, non-invasive way to predict which patients will benefit from extra fluids during bypass surgery. This measurement could help doctors make better decisions about fluid management without needing additional devices, which could improve your care during and after surgery.

During your bypass surgery, while you're already under anesthesia and being monitored, doctors will perform a simple ultrasound test by tilting the operating table slightly head-up and then head-down. They'll measure how much a vein in your chest collapses using the ultrasound camera already in place. This takes only a few minutes and causes no additional discomfort—it's part of your routine surgery monitoring.
