First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study was designed to see if a test using acetylcholine could predict whether people with congenital heart disease and high blood pressure in the lungs would develop worsening high blood pressure after surgery to close a heart shunt. The test would have measured how well the lung blood vessels relax. However, the study was withdrawn before enrolling any participants, so no results are available.
