NCT ID NCT06670781
First seen May 02, 2026 · Last updated May 16, 2026 · Updated 4 times
Summary
This study looks at two methods of performing the Valsalva maneuver (bearing down) during a heart ultrasound to detect a small hole called PFO, which can cause strokes. About 488 people who need this test will try both the standard self-directed method and a new goal-directed method using a pressure gauge. The goal is to see which method finds more PFOs, especially large ones, to improve diagnosis and treatment.
