Can tiny bubbles replace catheters for heart pressure checks?
Part of Heart & circulation clinical trials.
This trial tests if tiny ultrasound contrast bubbles can measure heart pressure, possibly replacing the need for catheter tubes. If you're already getting a heart catheterization, you may be able to join.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You need a cardiac catheterization (a routine heart exam with a thin tube) as part of your regular care.
- You must not be allergic to SonoVue or any of its ingredients (sulfur hexafluoride or PEG).
- You should not have a hole in your heart that lets blood flow from right to left.
- You must not have severe high blood pressure in your lungs (pulmonary hypertension) or uncontrolled high blood pressure.
- You must not have had a recent heart attack or unstable angina.

Other trials that look related to this one.
This trial studies whether a newer, faster ultrasound imaging method can better assess areas of the heart that may not get enough blood during stress. You may be eligible if you have known coronary artery disease or are considered low risk, and if you can safely undergo the stress ultrasound test.
This study uses a special ultrasound (echocardiography) with a contrast dye to see how blood flows through your lungs during exercise. It aims to help doctors better understand why patients get short of breath during activity.
This study tests a new way to use ultrasound (echocardiogram) to measure heart pressure in people who have both heart failure and atrial fibrillation (irregular heartbeat). Participants will have an ultrasound and a heart catheterization to see if the new ultrasound method can accurately detect elevated pressures.
This study tests whether using lung ultrasound at regular visits can help guide care for people with heart failure. It may help doctors spot worsening fluid problems earlier, before symptoms become severe.
This study looks at people with chronic heart failure with weaker pumping function and checks how well a lung/heart ultrasound can assess congestion (fluid buildup). If you qualify, you may help test a better way to evaluate your condition during a planned hospital visit.
This trial tests if using ultrasound to guide a catheter into the lung's blood vessels is a good way to diagnose pulmonary hypertension. It may help find a safer, more accurate method for diagnosis.
