Comparing two ways to do the Valsalva maneuver during a heart ultrasound
Part of Brain & nervous system, Genetic & congenital, Heart & circulation clinical trials.
This trial compares two ways of doing a breathing maneuver (Valsalva) during a heart ultrasound to see if it better detects a common hole in the heart (PFO). If you are already scheduled for this test, the study will help find the best method for you.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are already scheduled for a type of heart ultrasound called a 'bubble study' to check for a hole in the heart.
- You can understand and agree to the study procedures (provide informed consent).
- You can have a small IV line placed in your arm for the bubble test.
- You can do a short, controlled breath-hold move (called a Valsalva maneuver) during the test.
- You are okay with removing your face mask during the procedure.

This trial compares two devices that close a small opening in the heart called a PFO, which can let clots pass and cause strokes. If you've had a stroke or mini-stroke with no other cause, this study might help prevent future ones.
This study compares two types of replacement heart valves used in a procedure to treat aortic stenosis (a narrowed heart valve). It aims to see which valve is safer by measuring tiny particles that may travel to the brain during the procedure.
This trial compares two ways to check and fine-tune how well a new valve is working after a “valve-in-valve” TAVR procedure. It looks to see whether measurements from ultrasound of the heart (Doppler echocardiography) match results from a catheter test, which could help guide safer, more accurate valve care.
This trial uses a specialized ultrasound test (TEE with bubble study) to find a small opening in the heart called a PFO. It may help people who need this test to check for causes of certain health problems.
This study looks at the detailed flow pattern through a patent foramen ovale (PFO)—a small opening in the heart—and how it may relate to stroke, TIA, or migraine. Doctors use special ultrasound testing with contrast to better understand who is most affected.
This study tests a new dissolvable device that closes a common heart defect called a patent foramen ovale (PFO), which can cause strokes. The device is designed to prevent future strokes and eventually break down in the body.
