NCT ID NCT04034498

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study follows 50 people who have a hole in the wall between their heart's lower chambers (a perimembranous VSD). They received a special device to close the hole without open-heart surgery. Researchers are checking if the device stays in place and closes the hole properly, and if there are any serious side effects like heart block or infection.
