Long-term results after PFO closure surgery
Part of Brain & nervous system, Genetic & congenital, Heart & circulation clinical trials.
This study looks at how well patients do over time after having a hole in their heart (patent foramen ovale, or PFO) closed with a small device inserted through a vein. It may help doctors understand the benefits and risks of the procedure.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 19 years old or older.
- You have had a procedure to close a PFO with a small device through a vein.
- Your PFO closure happened between 2010 and March 2026.
- You have had at least one heart ultrasound after the procedure to check for blood flow.
- You are willing to give written permission to be in the study (if included in the future part of the study).

This trial looks at the safety and results of closing a PFO (a small hole in the heart) in people who have had a stroke or embolism with no other clear cause. If you qualify, doctors will close your PFO using a small tube inserted through a blood vessel and then follow your health over time.
This trial follows people who had a PFO (small hole in the heart) closure to check for long-term problems or complications related to the device or procedure.
This trial tests a new device to close a PFO (a small hole between the upper chambers of the heart) in people who have had a stroke caused by a blood clot. The goal is to prevent future strokes by blocking the hole.
This study looks at whether treating a history of “cryptogenic” stroke (stroke with no clear cause) using a patent foramen ovale (PFO) closure, plus medical therapy, is better than medical therapy alone. It focuses on people over 60 with a heart shunt seen on an ultrasound of the heart.
This trial tests whether closing a hole in the heart (a PFO) with a special device can help prevent another stroke after an unexplained stroke. You may be a candidate if your stroke likely happened because blood can pass through this PFO.
This trial compares two devices used to close a hole in the heart (called a PFO) in adults who have had a stroke or mini-stroke (TIA) within the last year. The goal is to see which device works better to prevent future strokes.
