Read our Heart Failure research guide →This trial is testing whether a special type of heart ultrasound (called contrast echocardiography) can safely measure the amount of blood in your lungs during exercise. Researchers want to see if this non-invasive ultrasound method can replace more invasive procedures, and whether the results differ between people with and without heart failure or lung blood vessel disease.
Currently, doctors must use an invasive catheter procedure to directly measure heart pressures during exercise. This trial aims to find a safer, simpler ultrasound-based method that could give doctors the same information without inserting a catheter into your heart.

You will undergo a heart ultrasound (echocardiogram) with a special contrast dye while exercising on a bike or treadmill. At the same time, you will also have the standard invasive catheter procedure you were already scheduled for. The ultrasound images will be compared with the catheter measurements to see how well the non-invasive method works.
